According to the results of an online survey issued by the prominent journal Nature, 20 percent of respondents, largely drawn from the scientific community, admitted to using brain-enhancing drugs such as Ritalin and Provigil.
Sixty-two percent of the scientists who had taken drugs used Ritalin, while 44 percent reported using Provigil. Only 14 percent tried beta blockers like propranolol.
The nearly 1,500 person survey was launched in the wake of a pair of recent articles that touched off a storm of questions about widespread neuroenhancer use by the scientific community.
