Masking and Conscious Perception

Masking and Conscious Perception

We examine dynamical aspects of conscious visual perception related to briefly presented stimuli and their possible neural underpinnings. The concept of the formation of an object as central to visual perception has been strongly supported from findings from backward masking. We particularly suggest that consciousness is related to the formation of closed thalamo-cortical loops mediated by the basal ganglia.
