HLTB21H3 Study Guide - Angioma, Cortical Blindness, Superior Temporal Sulcus
Document Summary
V2 is the second level: after v2, three distinct, parallel pathways emerge en route to the parietal cortex, superior temporal sulcus (sts), and inferior temporal cortex, for further processing, the parietal pathway, or dorsal stream, has a role in the visual guidance of movement, and the inferior temporal pathway, or ventral stream, is concerned with object perception (including color). Vision for action: this category is visual processing required to direct specific movements, vision for action is a function of the parietal visual areas in the dorsal stream. Each of these visual features is likely to be coded separately, and at least three distinct pathways within the dorsal stream run from area v1 to the parietal cortex: most of the visual impairments associated with lesions to the parietal cortex can be characterized as visuomotor or orientational, milner goodale model is an important theoretical advance in understanding how our visual brain is organized.
