Scientists opine that even healthy people can take pills that could boost their brain. With more and more stress on brain research and a new era of "cognitive enhancement", the use and development of of brain-stimulating drugs and devices by healthy people is on the cards.

"We call for a presumption that mentally competent adults should be able to engage in cognitive enhancement using drugs," said the researchers from Stanford law Professor Henry Greely and neuropsychology Professor Barbara Sahakian at the University of Cambridge in the United Kingdom. "From assembly line workers to surgeons, many different kinds of employee may benefit from enhancement and want access to it, yet they may also need protection from the pressure to enhance."

The authors, however, wanted more research on the subject, before the doctors and patients could weigh the pros and cons of taking such drugs.

Also the use of the drugs calls for an attention as these pills would be in high demand among middle-aged people who want youthful memory powers. The pills would also attract multitasking workers who need to keep track of multiple demands, said brain scientist, Martha Farah of the University of Pennsylvania.
