Abstract
Publisher Summary This chapter focuses on afferent and developmentally inherent mechanisms of form and motion processing in cat extrastriate cortex and presents the studies of the mechanisms of compensation for visual cortex damage in adult cats and newborn kittens. As part of these studies, it is investigated that the effects of both acute and long-term removal of inputs from different areas on the receptive- field properties of neurons in the posteromedial lateral suprasylvian (PMLS) extrastriate the visual area of cortex. This has allowed determining the role of various inputs in the elaboration of PMLS receptive fields in normal adult animals. In addition, it has provided evidence that the development of certain receptive field properties depends upon intrinsic characteristics of the PMLS neurons, not simply upon the particular inputs to the neurons. In normal adult cats, PMLS neurons respond selectively to stimulus motion (MS), direction (DS), orientation (OS), and spatial frequency content (SF). The orientation tuning is broad, and spatial resolution and optimal spatial frequency are low.
