If you’re a coffee or tea drinker, keep sipping: Caffeine may help protect against age-related cognitive decline. “Studies have indicated that caffeine—for example, roughly 500 milligrams daily, the equivalent of about five cups of coffee—may help stave off memory issues in humans,” says Bruce Citron, PhD, a neuroscientist at Bay Pines VA Healthcare System and the USF Morsani College of Medicine in Florida. (Experts warn against taking caffeine supplements, which flood your body with a lot of caffeine all at once.)
Omega-3 fatty acids—DHA in particular—contribute to a healthy brain. “The brain’s membranes use these fats to improve cellular structure and brain signaling, which translates into better cognitive function,” says Vasanti Malik, ScD, a research scientist in the Department of Nutrition at the Harvard T.H. Chan School of Public Health. DHA also quells chronic inflammation that can harm brain cells and lead to cognitive decline.
Power times prior times benefit minus cost of experimentation: (0.20 \times 0.30 \times 540) - 41 = -9. So the VoI is negative: because my default is that fish oil works and I am taking it, weak information that it doesn’t work isn’t enough. If the power calculation were giving us 40% reliable information, then the chance of learning I should drop fish oil is improved enough to make the experiment worthwhile (going from 20% to 40% switches the value from -$9 to +$23.8).
We all wish success came in a pill form. That was the premise of the hour and half Adderall commercial/ thriller film ‘Limitless’ starring Bradley Cooper. In the film he popped a transparent round pill and instantly his brain power skyrocketed- anything became possible. Most of us wished that pill existed- and now it does. Donepezil is a drug that is used to treat Alzheimers, but it’s effects on normal people make Adderall and Vyvanse look like a cup of coffee.
The Nootroo arrives in a shiny gold envelope with the words “proprietary blend” and “intended for use only in neuroscience research” written on the tin. It has been designed, says Matzner, for “hours of enhanced learning and memory”. The capsules contain either Phenylpiracetam or Noopept (a peptide with similar effects and similarly uncategorised) and are distinguished by real flakes of either edible silver or gold. They are to be alternated between daily, allowing about two weeks for the full effect to be felt. Also in the capsules are L-Theanine, a form of choline, and a types of caffeine which it is claimed has longer lasting effects.
As a student Seltzer used both Adderall and piracetam. Now, after a hiatus of several years, he has recently resumed taking neuroenhancers. In addition to piracetam, he took a stack of supplements that he thought helped his brain to function: fish oils, five antioxidants, a product called ChocoMind and a number of others, all available at the health-food store. He was thinking about adding modafinil, but hadn't yet. For breakfast every morning he concocted a slurry of oatmeal, berries, soy milk, pomegranate juice, flaxseed, almond meal, raw eggs and protein powder. The goal behind the recipe was efficiency: to rely on "one goop you could eat or drink that would have everything you need nutritionally for your brain and body. I wanted to be able to keep it down - that was it." (He told me this in the kitchen of his apartment; he lives with a roommate, who walked in while we were talking, listened perplexedly for a moment, then put a frozen pizza in the oven.)
Taurine (Examine.com) was another gamble on my part, based mostly on its inclusion in energy drinks. I didn’t do as much research as I should have: it came as a shock to me when I read in Wikipedia that taurine has been shown to prevent oxidative stress induced by exercise and was an antioxidant - oxidative stress is a key part of how exercise creates health benefits and antioxidants inhibit those benefits.
My worry about the MP variable is that, plausible or not, it does seem relatively weak against manipulation; other variables I could look at, like arbtt window-tracking of how I spend my computer time, # or size of edits to my files, or spaced repetition performance, would be harder to manipulate. If it’s all due to MP, then if I remove the MP and LLLT variables, and summarize all the other variables with factor analysis into 2 or 3 variables, then I should see no increases in them when I put LLLT back in and look for a correlation between the factors & LLLT with a multivariate regression.
Following up on the promising but unrandomized pilot, I began randomizing my LLLT usage since I worried that more productive days were causing use rather than vice-versa. I began on 2 August 2014, and the last day was 3 March 2015 (n=167); this was twice the sample size I thought I needed, and I stopped, as before, as part of cleaning up (I wanted to know whether to get rid of it or not). The procedure was simple: by noon, I flipped a bit and either did or did not use my LED device; if I was distracted or didn’t get around to randomization by noon, I skipped the day. This was an unblinded experiment because finding a randomized on/off switch is tricky/expensive and it was easier to just start the experiment already. The question is simple too: controlling for the simultaneous blind magnesium experiment & my rare nicotine use (I did not use modafinil during this period or anything else I expect to have major influence), is the pilot correlation of d=0.455 on my daily self-ratings borne out by the experiment?
(On a side note, I think I understand now why modafinil doesn’t lead to a Beggars in Spain scenario; BiS includes massive IQ and motivation boosts as part of the Sleepless modification. Just adding 8 hours a day doesn’t do the world-changing trick, no more than some researchers living to 90 and others to 60 has lead to the former taking over. If everyone were suddenly granted the ability to never need sleep, many of them would have no idea what to do with the extra 8 or 9 hours and might well be destroyed by the gift; it takes a lot of motivation to make good use of the time, and if one cannot, then it is a curse akin to the stories of immortals who yearn for death - they yearn because life is not a blessing to them, though that is a fact more about them than life.)
Research on animals has shown that intermittent fasting — limiting caloric intake at least two days a week — can help improve neural connections in the hippocampus and protect against the accumulation of plaque, a protein prevalent in the brains of people with Alzheimer’s disease. Research has also shown that intermittent fasting helped reduce anxiety in mice.
That left me with 329 days of data. The results are that (correcting for the magnesium citrate self-experiment I was running during the time period which did not turn out too great) days on which I happened to use my LED device for LLLT were much better than regular days. Below is a graph showing the entire MP dataseries with LOESS-smoothed lines showing LLLT vs non-LLLT days:
“By drawing on more than fifteen years of scientific research and experience, Dr. Mosconi provides expert advice to prevent medical decline and sharpen memory. Her brain healthy recipes will help you maintain peak cognitive performance well into old age and therefore delay and may even prevent the appearance of debilitating diseases like Alzheimer’s.”
Choline works best when stacked with nootropics. Stacking choline with a nootropic can also help prevent or reduce side effects. Often, people find that they get headaches when they take nootropics by themselves and that stacking them with choline helps reduce this problem. It is usually suggested to stack nootropics with a choline source, especially if you do not get enough from your diet.
The beauty of this stack is that nature has already given us a perfectly packaged combination of caffeine and theanine in the form of green tea, whether a cup of green tea, a bowl of matcha tea, or even a green tea extract supplement as a substitute for a cup of coffee. This is an especially convenient stack to use during a time when you don’t want the excess stimulation of coffee or caffeine in isolation, such as during an evening dinner at a restaurant or in the latter stages of a workday when a cup of coffee might keep you awake too late into the night.
I noticed what may have been an effect on my dual n-back scores; the difference is not large (▃▆▃▃▂▂▂▂▄▅▂▄▂▃▅▃▄ vs ▃▄▂▂▃▅▂▂▄▁▄▃▅▂▃▂▄▂▁▇▃▂▂▄▄▃▃▂▃▂▂▂▃▄▄▃▆▄▄▂▃▄▃▁▂▂▂▃▂▄▂▁▁▂▄▁▃▂▄) and appears mostly in the averages - Toomim’s quick two-sample t-test gave p=0.23, although a another analysis gives p=0.138112. One issue with this before-after quasi-experiment is that one would expect my scores to slowly rise over time and hence a fish oil after would yield a score increase - the 3.2 point difference could be attributable to that, placebo effect, or random variation etc. But an accidentally noticed effect (d=0.28) is a promising start. An experiment may be worth doing given that fish oil does cost a fair bit each year: randomized blocks permitting an fish-oil-then-placebo comparison would take care of the first issue, and then blinding (olive oil capsules versus fish oil capsules?) would take care of the placebo worry.
The acid is also known to restore the vitamin C and E levels in the body. Alpha Lipoic Acid’s efficient antioxidant property protects brain cells from damage during any injury. This helps in making sure that your brain functions normally even if there is any external or internal brain injury. OptiMind, one of the best nootropic supplements that you can find today contains Alpha Lipoic Acid that can help in enhancing your brain’s capabilities.
Research does not support that drugs like Ritalin help students do well in school. Studies show that prescription stimulants do not help to improve learning or thinking in those who do not actually have ADHD. Further, research reveals that students who abuse prescription stimulants have lower GPAs than students who do not abuse the drugs. Although Ritalin improves concentration, this effect is largely misunderstood among non-prescribed users. These illicit users mistakenly believe that they can use a drug out of its prescribed context, thinking they can reap the benefits intended for legitimate users.
The experiment then is straightforward: cut up a fresh piece of gum, randomly select from it and an equivalent dry piece of gum, and do 5 rounds of dual n-back to test attention/energy & WM. (If it turns out to be placebo, I’ll immediately use the remaining active dose: no sense in wasting gum, and this will test whether nigh-daily use renders nicotine gum useless, similar to how caffeine may be useless if taken daily. If there’s 3 pieces of active gum left, then I wrap it very tightly in Saran wrap which is sticky and air-tight.) The dose will be 1mg or 1/4 a gum. I cut up a dozen pieces into 4 pieces for 48 doses and set them out to dry. Per the previous power analyses, 48 groups of DNB rounds likely will be enough for detecting small-medium effects (partly since we will be only looking at one metric - average % right per 5 rounds - with no need for multiple correction). Analysis will be one-tailed, since we’re looking for whether there is a clear performance improvement and hence a reason to keep using nicotine gum (rather than whether nicotine gum might be harmful).

In my last post, I talked about the idea that there is a resource that is necessary for self-control…I want to talk a little bit about the candidate for this resource, glucose. Could willpower fail because the brain is low on sugar? Let’s look at the numbers. A well-known statistic is that the brain, while only 2% of body weight, consumes 20% of the body’s energy. That sounds like the brain consumes a lot of calories, but if we assume a 2,400 calorie/day diet - only to make the division really easy - that’s 100 calories per hour on average, 20 of which, then, are being used by the brain. Every three minutes, then, the brain - which includes memory systems, the visual system, working memory, then emotion systems, and so on - consumes one (1) calorie. One. Yes, the brain is a greedy organ, but it’s important to keep its greediness in perspective… Suppose, for instance, that a brain in a person exerting their willpower - resisting eating brownies or what have you - used twice as many calories as a person not exerting willpower. That person would need an extra one third of a calorie per minute to make up the difference compared to someone not exerting willpower. Does exerting self control burn more calories?
Attention Deficit and Hyperactivity Disorder (ADHD) is a condition that relates to a collection of behavioural symptoms such as hyperactivity, impulsiveness and inattentiveness. It is most commonly diagnosed in childhood between the ages of 6 and 12 when disruptive behaviour begins to show, however, due to a growing awareness of the condition, it is also becoming common among adults. According to the thinktank Demos, the cost of undiagnosed ADHD in adults in the UK who are unable to work or hold down a full-time job are estimated to cost billions of pounds to the nation. They warn that too many may be going through life struggling, unable to access the support ot diagnosis they need, which means there could be a huge amount of wasted talent.
Increase your memory, alertness, energy and focus with the most revolutionary “limitless” pill ever created. As we age, our brains start to slow down both in reaction time and in the recalling of memories. That’s why we need to not only regain our mental capacity, we need to enhance it to such heights that we go well beyond where we started. When you use the dietary supplement Addium, you can total replenish and revitalize your mental alertness in a safe, all-natural way. Made of some of the most powerful brain enhancing ingredients on the market, Addium can be used each day to increase memory function, enhance brain power, increase physical energy and stay sharper and more focused. Don’t just settle for feeling like everyone else; it’s time to take your mind to a limitless state of mental preparedness. Addium Brain Enhancing Dietary Supplement also contains the following benefits: • Boosts your capacity for learning • Increases your alertness and focus • Safe and all natural • Promotes strong brain function • Enhances memory and performance Addium contains: Vitamin B6 - An economical source for cardio health and energy metabolism. Addium contains a Proprietary Blend of: Acetyl L-Carnitine - Energizes the mind and promotes concentration. L-Theanine - Enhances endocrine function, stimulating some brain waves and leaving others unaffected. Caffeine - Increase mental alertness. Rhodiola Rosea Extract - Fights the physical and mental effects of stress. Bacopa Monnieri Extract – This ingredient increases cerebral blood flow and cognitive function at the same time.
One thing I did do was piggyback on my Noopept self-experiment: I blinded & randomized the Noopept for a real experiment, but simply made sure to vary the Magtein without worrying about blinding or randomizing it. (The powder is quite bulky.) The correlation the experiment turned in was a odds-ratio of 1.9; interesting and in the right direction (higher is better), but since the magnesium part wasn’t random or blind, not a causal result.
I largely ignored this since the discussions were of sub-RDA doses, and my experience has usually been that RDAs are a poor benchmark and frequently far too low (consider the RDA for vitamin D). This time, I checked the actual RDA - and was immediately shocked and sure I was looking at a bad reference: there was no way the RDA for potassium was seriously 3700-4700mg or 4-5 grams daily, was there? Just as an American, that implied that I was getting less than half my RDA. (How would I get 4g of potassium in the first place? Eat a dozen bananas a day⸮) I am not a vegetarian, nor is my diet that fantastic: I figured I was getting some potassium from the ~2 fresh tomatoes I was eating daily, but otherwise my diet was not rich in potassium sources. I have no blood tests demonstrating deficiency, but given the figures, I cannot see how I could not be deficient.
Woo understands that when selling brain drugs, skepticism comes with the territory. "The typical first reaction is, this is bullshit, you guys are snake-oil salesmen," he says. "We're not medical doctors nor biochemistry experts, but we are experts in building teams and building products. Like how Elon Musk attacks rockets and electric cars from 'first principles,' we see ourselves as applying Silicon Valley aesthetics and operational know-how to the murky world of nootropics."
Some supplement blends, meanwhile, claim to work by combining ingredients – bacopa, cat's claw, huperzia serrata and oat straw in the case of Alpha Brain, for example – that have some support for boosting cognition and other areas of nervous system health. One 2014 study in Frontiers in Aging Neuroscience, suggested that huperzia serrata, which is used in China to fight Alzheimer's disease, may help slow cell death and protect against (or slow the progression of) neurodegenerative diseases. The Alpha Brain product itself has also been studied in a company-funded small randomized controlled trial, which found Alpha Brain significantly improved verbal memory when compared to adults who took a placebo.
A recent study at the University of Innsbruck in Austria found that participants that drank two cups of coffee per day improved memory, reaction time, and neuron signaling, more than the control. More notably, the 676 daily coffee drinker participants experienced less mental decline than nondrinkers over a ten-year period. In other words, bottoms up on your cup of Joe!
By blending proven natural cognitive enhancers and naturally occurring smart brain health supporting amino acids like Cordyceps-Sinensis Extract , Coenzyme Q10 , Chlorella (from Green Algae) and Omega-3 Extract to maximize acetylcholine levels with other essential brain health supporting vitamins and amino acids, our powerful and effective brain health supplement assists in elevating serotonin and GABA levels, crucial components to remaining calm, alert, focused and mentally driven while under pressure or stress.
Compared with those reporting no use, subjects drinking >4 cups/day of decaffeinated coffee were at increased risk of RA [rheumatoid arthritis] (RR 2.58, 95% CI 1.63-4.06). In contrast, women consuming >3 cups/day of tea displayed a decreased risk of RA (RR 0.39, 95% CI 0.16-0.97) compared with women who never drank tea. Caffeinated coffee and daily caffeine intake were not associated with the development of RA.
Recent findings also suggest that taking extra vitamins could help preserve memory, especially as we age. Researchers at Australia's University of Sydney tested 117 people in a retirement home by putting them through a battery of mental tests that included remembering a string of words, listing as many words as possible that begin with a certain letter of the alphabet, and doing mental addition and subtraction. Those who regularly took vitamin C, they found, scored higher on the tests.
It’s not easy to make it in the modern world, which asks you to be focused and sharp all the time. You have to be creative and learn the new skills all the time. That’s a heavy burden for your brain cells. One day, sooner or later, you have to accept the fact that your brain power and effectiveness are no longer as impressive and reliable as once they were. Brain Pill can help. You don’t have to force yourself to accept your new reality of limited focus and weak ability to learn new things. Brain Pill can refresh your mental clarity and improve your problem-solving and decision-making skills.
Pyritinol: Pyritinol has anti-oxidant effects for supporting the long-term health of the brain. But its primary benefit is aiding glucose uptake for periods of extended mental strain. If you are studying or working for a long period of time, your brain will start to diminish its glucose (sugar) stores which are the primary way that the brain derives its energy.
Be patient. Even though you may notice some improvements right away (sometimes within the first day), you should give your brain supplement at least several months to work. The positive effects are cumulative, and most people do not max out their brain potential on a supplement until they have used it for at least 90 days. That is when the really dramatic effects start kicking in!
We reached out to several raw material manufacturers and learned that Phosphatidylserine and Huperzine A are in short supply. We also learned that these ingredients can be pricey, incentivizing many companies to cut corners. A company has to have the correct ingredients in the correct proportions in order for a brain health formula to be effective. We learned that not just having the two critical ingredients was important – but, also that having the correct supporting ingredients was essential in order to be effective.
Whole grains. Whole grains, such as oatmeal, whole-grain breads, and brown rice can reduce the risk for heart disease. "Every organ in the body is dependent on blood flow," says Pratt. "If you promote cardiovascular health, you're promoting good flow to the organ system, which includes the brain." While wheat germ is not technically a whole grain, it also goes on Kulze's "superfoods" list because in addition to fiber, it has vitamin E and some omega-3s. Kulze suggests 1/2 cup of whole-grain cereal, 1 slice of bread two-thee times day, or 2 tablespoons of wheat germ a day.

Most notably, Jessica is recognized (by her parents) for a 3 minute vocal solo at Carnegie Hall (at 13), by her friends for her amazing Raw Vegan Peanut Butter Chocolate Chip Cookie recipe, and also by her yogi friends for her recent mastery of Camel Pose. In all seriousness, Jessica is beyond excited to write for SnackNation, and to share her passion for health, wellness, and delicious foods.
We have established strict criteria for reviewing brain enhancement supplements. Our reviews are clear, detailed, and informative to help you find supplements that deliver the best results. You can read our reviews, learn about the best nootropic ingredients, compare formulas, and find out how each supplement performed according to specific criteria.
Capsule Connection sells 1000 00 pills (the largest pills) for $9. I already have a pill machine, so that doesn’t count (a sunk cost). If we sum the grams per day column from the first table, we get 9.75 grams a day. Each 00 pill can take around 0.75 grams, so we need 13 pills. (Creatine is very bulky, alas.) 13 pills per day for 1000 days is 13,000 pills, and 1,000 pills is $9 so we need 13 units and 13 times 9 is $117.
Jesper Noehr, 30, reels off the ingredients in the chemical cocktail he’s been taking every day before work for the past six months. It’s a mixture of exotic dietary supplements and research chemicals that he says gives him an edge in his job without ill effects: better memory, more clarity and focus and enhanced problem-solving abilities. “I can keep a lot of things on my mind at once,” says Noehr, who is chief technology officer for a San Francisco startup.
Began double-blind trial. Today I took one pill blindly at 1:53 PM. at the end of the day when I have written down my impressions and guess whether it was one of the Adderall pills, then I can look in the baggy and count and see whether it was. there are many other procedures one can take to blind oneself (have an accomplice mix up a sequence of pills and record what the sequence was; don’t count & see but blindly take a photograph of the pill each day, etc.) Around 3, I begin to wonder whether it was Adderall because I am arguing more than usual on IRC and my heart rate seems a bit high just sitting down. 6 PM: I’ve started to think it was a placebo. My heart rate is back to normal, I am having difficulty concentrating on long text, and my appetite has shown up for dinner (although I didn’t have lunch, I don’t think I had lunch yesterday and yesterday the hunger didn’t show up until past 7). Productivity wise, it has been a normal day. All in all, I’m not too sure, but I think I’d guess it was Adderall with 40% confidence (another way of saying placebo with 60% confidence). When I go to examine the baggie at 8:20 PM, I find out… it was an Adderall pill after all. Oh dear. One little strike against Adderall that I guessed wrong. It may be that the problem is that I am intrinsically a little worse today (normal variation? come down from Adderall?).
The nootropic sulbutiamine, of the synthetic B-vitamin-derived nootropics family, is generally considered a low-risk supplement; however, some users have reported that the supplement has addictive qualities. While there is no firm evidence of sulbutiamine addiction, the risk may increase at high dosages. For instance, users who consume this supplement for 10 consecutive days may experience withdrawal for two to five days. There are also increased risks when sulbutiamine is taken with antipsychotic medications.
I noticed on SR something I had never seen before, an offer for 150mgx10 of Waklert for ฿13.47 (then, ฿1 = $3.14). I searched and it seemed Sun was somehow manufacturing armodafinil! Interesting. Maybe not cost-effective, but I tried out of curiosity. They look and are packaged the same as the Modalert, but at a higher price-point: 150 rather than 81 rupees. Not entirely sure how to use them: assuming quality is the same, 150mg Waklert is still 100mg less armodafinil than the 250mg Nuvigil pills.
REPUTATION: We were blown away by the top-notch reputation that Thrive Naturals has in the industry. From the consumers we interviewed, we found that this company has a legion of loyal brand advocates. Their customers frequently told us that they found Thrive Naturals easy to communicate with, and quick to process and deliver their orders. The company has an amazing track record of customer service and prides itself on its Risk Free No Questions Asked 1-Year Money Back Guarantee. As an online advocate for consumer rights, we were happy to see that they have no hidden fees nor ongoing monthly billing programs that many others try to trap consumers into.
With a lack of reviews and a formulation containing some questionable ingredients that we could not find to benefit consumers, together with the possibility of the product being sub-standard, we placed this product in our # 4 ranking. Its redeeming features however, include the fact that they use all-natural ingredients plus, the price is cheap, if you are into taking a risk about the quality of the product.
As mentioned above, eating foods that are rich in indigestible fibre such as vegetables and fruits, as well as eating good fats that are found in grass-fed butter, nuts and seeds, olive oil, coconut oil and avocado, provide bacteria with prebiotics that help to produce the ‘friendly’ short-chain fatty acids such as butyrate. Avoiding processed foods that contain calcium propionate, which lead to higher levels of propionic acid - the not so friendly short-chain fatty acid - is also another key strategy to support the gut-brain link.
Sure, you could certainly swallow too much St. John’s Wort and create the same type of serotonin or neurotransmitter issues you could create with a synthetic smart drug, but it’s far more difficult to harm yourself with a nootropic compared to a synthetic smart drug. Although synthetic, laboratory-designed nootropics do indeed exist, even those are not as harsh on the biology as a smart drug and have a mechanism of action that is a bit more natural. Let’s begin with the more natural nootropics.
The available literature on cognitive enhancing practices at times appears to lump together nootropics and “smart drugs.” Smart drugs are not officially defined, but references to this group generally include Provigil (modafinil), Adderall and Ritalin. Any confusion about the addiction potential of different brain-enhancing drugs can spread misinformation about the individual drugs. There are many nootropics on the market, so the best practice is to focus on the addiction potential of each nootropic of interest or concern.
Most of the most solid fish oil results seem to meliorate the effects of age; in my 20s, I’m not sure they are worth the cost. But I would probably resume fish oil in my 30s or 40s when aging really becomes a concern. So the experiment at most will result in discontinuing for a decade. At $X a year, that’s a net present value of sum $ map (\n -> 70 / (1 + 0.05)^n) [1..10] = $540.5.
Whole grains, which you digest slowly, provide fuel for your brain. (Although your brain accounts for only 3 percent of your total body weight, it uses 20 percent of energy.) Rich sources include brown rice, whole wheat bread, quinoa, bran flakes, oats, and barley. According to Science Daily, brain food containing whole grains can boost cardiovascular health, which in turn enhances the flow of blood to the brain. They contain more intact nutrients than processed white flour, including vitamin E, antioxidants, and fiber. When these work together to increase blood flow, the integrity of brain cells is better preserved. To keep your brain sharp, go beyond your diet and incorporate these healthy brain-boosting habits into your routine.
Ampakines bind to AMPARs to block uptake of glutamate, thereby increasing synaptic responses, and this has indeed been shown to minimize the effects of conditions such as Alzheimer’s. Ampakines are also being studied as possible treatments for schizophrenia, depression, ADHD and more. But there is a huge risk associated with ampakine consumption. They are now tightly regulated because if you exceed a safe dosage, you will begin to suffer neuronal damage from glutamate toxicity, which leads to some of the very conditions that ampakines are thought to attenuate. Ampakine consumption can also lead to a decrease in long-term synaptic depression (LTD), a process by which specific synapses (the space between neurons across which information is sent) are intentionally weakened in order to avoid a plateau in the efficiency of your synapses. In other words, it allows your neurons and their connections to continue growing in efficiency. LTD is believed to be necessary for healthy synaptic plasticity (the adaptability of synapses), memory function and motor skills. To be honest, there is debate over whether cognitive functions like motor learning are truly dependent upon LTD, but it is possible that if you were to take a higher-than-recommended dose of an ampakine, the overstimulation that would result may lead to suppressed LTD and consequently to poor memory and motor function.
