The ventral stream (or “vision-for-perception” pathway) is believed to mainly subserve recognition and discrimination of visual shapes and objects, whereas the dorsal stream (or “vision-for-action” pathway) has been primarily associated with visually guided reaching and grasping based on the moment-to-moment analysisClick to see full answer. Besides, what is the ventral visual pathway?The ventral visual pathway is a functional stream involved in the visual recognition of objects. While areas V1, V2, and V4 are involved in the processing of basic level visual features such as edges, contours, and color, the inferior temporal cortex is suggested to process complex shapes (Ungerleider & Haxby, 1994).Additionally, what is happening in the dorsal visual pathway? Definition. The dorsal visual pathway is a functional stream originating in primary visual cortex and terminating in the superior parietal lobule that is responsible for the localization of objects in space and for action-oriented behaviors that depend on the perception of space. Regarding this, what are the dorsal and ventral visual processing streams specialized for? According to their data, the ventral ‘perceptual’ stream computes a detailed map of the world from visual input, which can then be used for cognitive operations, and the dorsal ‘action’ stream transforms incoming visual information to the requisite egocentric (head-centered) coordinate system for skilled motor planningWhat are the two visual systems?This two-visual-systems hypothesis (TVSH) proposes that the ventral stream of visual pathways in the cerebral cortex, which delivers up our visual experience of the world, works in an allocentric frame of reference, whereas the dorsal stream, which mediates the visual control of action, uses egocentric frames of
