Cognition Enhancer Research

oschobero writes to tell us the Economist has a look at pharmaceutical research as it applies to cognition enhancers. While the research is obviously focused on things like Alzheimer's, Parkinson's, and schizophrenia, the resulting drugs may also have a benefit to healthy minds. "Provigil and Ritalin really do enhance cognition in healthy people. Provigil, for example, adds the ability to remember an extra digit or so to an individual's working memory (most people can hold seven random digits in their memory, but have difficulty with eight). It also improves people's performance in tests of their ability to plan. Because of such positive effects on normal people, says the report, there is growing use of these drugs to stave off fatigue, help shift-workers, boost exam performance and aid recovery from the effects of long-distance flights."

Paradoxically, another glutamate-booster, D-cycloserine, is being tested not to enhance memory, but to abolish it. The paradox is resolved because unlearning (or "extinction", in neurological parlance) is a process similar in its details to learning.

By binding to certain glutamate receptors, D-cycloserine selectively enhances extinction, suppressing the effects of conditioned associations such as anxiety, addiction and phobias. According to Dr Robbins, experiments have shown that if a rat is given a cue that it previously associated with fear at the same time as it receives D-cycloserine, the bad memory can be eliminated. Not only may this help remove unpleasant memories... Does this mean that people might be able to unsee things *coughgoatsecough*

Re:Provigil.

I've taking Provigil.

That's a great first sentence to promote a cognition-enhancing drug.
