Document Summary
Retinotopic maps in humans: distance between a and b and between c and d are similar on the retina, but different in the cortex, neighbouring locations in visual scene will stimulate neighbouring regions on the retina. Tiling: location columns cover the entire receptive field. These are substantial, and likely responsible for top-down" processing. D. f. ": damaged ventral pathway from carbon monoxide poisoning, exhibited a visual form agnosia - could not name familiar objects. Cortical modularity: module - a brain structure that processes information about specific stimuli. Inferotemporal (it) cortex in monkeys: responds best to faces with little response to non-face stimuli, temporal lobe damage in humans results in prosopagnosia. Distributed representation: distributed representation, a stimulus causes neural activity in a number of different areas of the brain, activity is distributed across the brain. textbook describes two fmri studies that provide evidence of distributed representation in human vision.
