Chapter 6
Perception A rapid, automatic, unconscious process by which we recognize what is
represented by the information provided by our sense organs
Module a block of cortical tissue that receives information from the same group of receptor cells
Receptive fieldthat portion of the visual field in which the presentation of visual stimuli will
produce an alternation in the firing rate of a particular neuron
Ventral streamthe flow of information from the primary visual cortex to the visual associated
area in the lower temporal lobe; used to form the perception of an objects shape,
colour, and orientation (the what system)
Dorsal streamthe flow of information from the primary visual cortex to the visual associated
area in the lower parietal lobe; used to form perception of the object in 3D space
(the where” system)
Visual agnosia the inability of a person who is not blind to recognize the identity of an object
visually; caused by damage to the visual associated cortex
Prosopagnosia a form of visual agnosia characterized by difficult in the recognition of peoples
faces; caused by damage to the visual associated cortex
Fusiform face area (FFA) a region of the ventral stream of the visual system that contains face-
recognizing circuits
Extrastriate body area (EBA) a region of the occipital cortex, next to the primary visual cortex, that
responds to forms resembling the human body
Parahippocampal place area(PPA) a region of the ventral stream below the hippocampus that is
activated by visual scenes
Cerebral achromatopsiathe inability to discriminate among different hues, caused by damage to the
visual association cortex (kinda like colour blindness)
