Document Summary
A rapid, automatic, unconscious process, by which we recognize what is represented by the information provided by our sense organs. A viewer can recognize familiar objects and learn appearances of new objects. Learned from the thalamus and primary visual cortex. Module: block of cortical tissue that receives info from the same group of receptor cells. Receptive field: 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 stream: flow of info from the primary visual cortex to the visual association area in the lower temporal lobe; used to form the perception of an object"s shape, colour, and orientation (the what system) Dorsal stream: flow of info from the primary visual cortex to the visual association area in the parietal lobe; used to form the perception of an object"s location in three- dimensional space (the where system)
