PSYC 3350 Lecture Notes - Lecture 3: Fusiform Face Area, Receptive Field, Grandmother Cell
Document Summary
Cooper center-surround antagonism center-surround organization: charles gross, complex cells, contrast threshold, distributed coding. 10. easy problem of consciousness: end-stopped cells, excitatory area. 13. experience- dependent plasticity: feature detectors, fusiform face area said that one"s perception of white light is influenced by belongingness. an area"s appearance is influenced by the part of the surroundings to which the area appears to belong. Dark bars make grey appear lighter. placed kittens in tubes with only one line orientation. After 5 months, kittens appeared blind to the orientations they weren"t exposed to. Demonstrates the effects of selective rearing. spot of light becomes large enough that it begins to cover the inhibitory area. Stimulating the inhibitory surround causes a decrease in the neuron"s firing rate. area in the center of the receptive field responds differently to light than area in the surround. Idea that response properties of neurons can be shaped by perceptual experience.
