Presynaptic inhibition of transmission from identified interneurons in locust central nervous system.

abstract：:Detection and discrimination of odors generally, if not always, occurs against an odorous background. On any given inhalation, olfactory receptor neurons will be activated by features of both the target odorant and features of background stimuli. To identify a target odorant against a background therefore, the olfacto...
