Abstract:We investigated the GABA-induced inactivation of V2 neurons and terminals on the
receptive field properties of this area in an anesthetized and paralyzed
Cebus apella monkey. Extracellular single-unit activity was
recorded using tungsten microelectrodes in a monkey before and after
pressure-injection of a 0.25 or 0.5 M GABA solution. The visual stimulus
consisted of a bar moving in 8 possible directions. In total, 24 V2 neurons were
studied before and after blocker injections in 4 experimental sessions followi… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
