This chapter reviews the functional anatomical bases of visual perception in the retina, the lateral geniculate nucleus (LGN) in the visual thalamus, the primary visual cortex (area V1, also called the striate cortex, and Brodmann area 17), and the extrastriate visual cortical areas of the dorsal and ventral pathways. The sections dedicated to the retina and LGN review the basic anatomical...
Microsaccades are the largest and fastest of the fixational eye movements, which are involuntary eye movements produced during attempted visual fixation. In recent years, the interaction between microsaccades, perception and cognition has become one of the most rapidly growing areas of study in visual neuroscience. The neurophysiological consequences of microsaccades have been the focus of less attention,...
Our eyes move continually, even while we fixate our gaze on an object. If fixational eye movements are counteracted, our perception of stationary objects fades completely, due to neural adaptation. Some studies have suggested that fixational microsaccades refresh retinal images, thereby preventing adaptation and fading. However, other studies disagree, and so the role of microsaccades remains unclear...
