In about a third of the sample of area 19 neurons, inactivation of higher-order pattern-processing PTV cortex resulted in significant changes in the magnitude of their peak responses to optimally oriented elongated moving bars. Only occasionally, silencing feedback signals from PTV resulted in an abolishment of the spike-responses of area 19 neurons. In a small proportion of area 19 cells, feedback from PTV appears to play a modulatory role in relation to such RF properties as optimal orientation and/or width of orientation-tuning curves. In a large proportion of area 19 cells and a proportion of area 17 cells, feedback from PTV plays a modulatory role in relation to stimulus velocity preferences and/or direction selectivity, that is, the properties which are usually believed to be determined by the inputs from the dorsal thalamus and/or feedforward inputs from the primary visual cortices. Thus, apparent specialization of area 19 for processing information about stationary/slowly moving visual stimuli is at least partially determined, by the feedback from the higher-order pattern-processing visual area.
