Nootropics and the Brain

From Wikipedia:

Nootropics (English pronunciation: /noʊ.əˈtrɒpɪks/ noh-ə-TROP-iks), also known as cognitive enhancers are supplements, and other substances that improve cognitive function, particularly executive functions, memory, creativity, or motivation, in healthy individuals.

The word nootropic was coined in 1972 by a Romanian psychologist and chemist, Corneliu E. Giurgea, from the Greek words νοῦς (nous), or “mind”, and τρέπειν (trepein), meaning to bend or turn.
