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. Moreover, 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 planningLikewise, what does the ventral stream do? Ventral stream: a pathway that carries visual information from the primary visual cortex to the temporal lobe. According to one widely-accepted hypothesis, the ventral stream (so named because of the path it takes along the ventral side of the brain) carries information related to object form and recognition. Also asked, 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).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.
