What are areas 17, 18, and 19?
|
Areas in which visual information proceeds in a distributed hierarchical process with multiple parallel and interconnecting pathways at each level.
|
areas in which visual information turns me on, like seeing your boobies
|
|
|
V1
|
The (striate cortex) is the primary vision area: it receives the largest input from the lateral geniculate nucleus of the thalamus and it projects to all other occipital regions. V1 is the first processing level in the hierarchy.

V2
|
Also projects to all other occipital regions. The second level.

projects to all

V3
|
Concerned with what Zeki calls "dynamic form"--that is the shape of objects in motion.
|
dynamic form

|
STS
|
Seperates the superior and middle temporal gyri-contains a significant amount of neocortex - can be divided into many subregions and is multimodal, receiving input from auditory, visual and somatic regions as well as the other two polymodal regions (frontal and partetal lobes)
and the paralimbic cortex--these multimodal inputs are involved in cateforization abilities used for perception and memory processes-also important in cross-modal matching -- analyzes biological motion (movements of particular relevance to a species) -- neurons here may be responsive to faces in different orientations as well as to bodies moving in a responsive to faces in different orientations as well as to bodies moving in a particular direction. |

|
Apperceptive agnosia
|
Broad category of visual agnosia in which elementary sensory functions appear to be relatively intact but a perceptual deficit that prevents recognition of an object in present.
|
|
|
|
Simultagnosia
|
Symptom in which a person is unable to perceive more than one object at a time.
|
|
|
|
associative agnosia
|
Form of agnosia in which there is an object-identification deficit in the context of a preserved ability to copy or match stimuli presented in the affected modality.
|
|
|
|
prosopagnosia
|
Inability, not explained by defective vusual acuity or reduced consciousness or alertness, to recognize familiar faces; rare in pure form and thought to be secondary to right parietal lesions.
|
|
|
|
vision for action
|
Visual processing required to direct specific movements, for example: when reaching for a particular object such as a cup.
|
|
|
|
action for vision
|
"Top down" process, the view actively searches for only part of the target object and attends selectively focusing on distinct features of the stimulus.
