1. The iontophoretic application of bicuculline, an antagonist of GABA, the putative inhibitory transmitter in the visual cortex, has been used to examine the contribution of post-synaptic inhibitory processes to the directional selectivity of simple, complex and hypercomplex cells in the cat's striate cortex.2. The directional selectivity of simple cells was significantly reduced or eliminated during the iontophoretic application of bicuculline. This supports the view that the selectivity is… CONTINUE READING
