Developmentally induced loss of direction-selective neurons in the cat's lateral suprasylvian visual cortex.
Single-cell recordings were carried out in the posteromedial lateral suprasylvian (PMLS) visual cortex of cats reared in an environment illuminated by 8-Hz stroboscopic flashes. These cats had a reduced proportion of direction-selective cells (8%) compared to PMLS cortex of normal cats (79%). Other receptive-field properties and ocular dominance of the neurons appeared normal. These results have implications for understanding the mechanisms of PMLS-cortex development and for interpreting behavioral studies of strobe-reared cats.
