6.3 Parallel Processing in the Visual Cortex Flashcards
Ventral stream
Visual paths in the temporal cortex that are specialized for identifying and recognizing objects; the “what” path
Secondary visual cortex (area V2)
Area of the brain that processes information from the primary visual cortex and transmits it to additional areas
Visual agnosia
An inability to recognize objects despite otherwise satisfactory vision
Dorsal stream
Visual path in the parietal cortex that helps the motor system locate objects; the “where” path
Inferior temporal cortex
Portion of the cortex where neurons are highly sensitive to complex aspects of the shape of visual stimuli within very large receptive fields
Prosopagnosia
The inability to recognize faces due to damage of several brain areas
Fusiform gyrus
Brain area of the inferior temporal cortex that recognizes faces
Middle temporal cortex (MT or V5)
Area of the brain that detects moving objects
Saccades
Voluntary eye movements
Motion blindness
An impaired ability to perceive movement
