In the course of this work, he has pioneered several new approaches in the fruit fly that have had important implications for mammalian neurobiology, including: the demonstration that the fruit fly has a sleep - like behavior similar to that of mammals, studies of physiological and behavioral consequences of mutations in a neurotransmitter system affecting one of the brain's principal chemical signals, studies making highly localized genetic alterations in the nervous system to alter behavior, and molecular
identification of genes causing naturally occurring variation in behavior.
