Document Summary
Area v1: laminar (striped) organization most distinct of all cortical areas, aka. Color vision: primary job of v4, but distributed throughout occipital cortex. Output to all other levels: secondary visual cortex (v2) Output to all other levels: after v2. Output to parietal lobe dorsal stream. Output to the inferior temporal lobe ventral stream. Object perception: able to associate object with a memory or label. Output to superior temporal sulcus (sts sts stream. Vision begins in v1 that is heterogeneous, & then travels to more specialized cortical zones. Selective lesions up the hierarchy produce specific visual deficits. Lesions to v1 are not aware of seeing. Multiple visual regions in the temporal, parietal, & frontal lobes indicate there is sophisticated adaptation system and to act upon it. Vision: not unitary, composed of many specific forms of processing, 5 categories for vision. Vision for action: parietal visual areas in the dorsal stream, reaching, ducking, catching. Visual recognition: temporal lobes, object recognition.
