Mike Kuhar, a neuroscientist at Yerkes National Primate Research Center, introduced the
topic of cognitive enhancers or â $ œsmart drugs.â $ He described one particular class of proposed cognitive enhancers, called ampakines, which appear to
improve functioning
on certain tasks without stimulating signals throughout the brain. Kuhar questioned whether â $ œsmart drugsâ $ pose unique challenges, compared to other types of drugs.
