Document Summary

Psy1101: lecture 9 and 10 perception (on midterm 2) Visual cortex: depicts location, distance in visual cortex. Mosaics (as in 1st slide): each has 150 000 neurons, 2500 of those tiles in cortex. Each mosaic corresponds to area in primary visual cortex. Information from retina--> primary visual cortex--> secondary (form and motion) in brain--> association areas (might not know what you"re looking at, or where it is- if damaged) Certain neurons are more responsive to certain things: rotation: one receptor for every angle, contour, edge, colour, spirals. Bottom up: stimulus--> sensory receptors (eyes, ears, nose, such as the receptors in the cochlea that are imbedded in the basilar membrane)--> neural impulses--> brain (occipital, auditory: temporal area) whereas perception is a top down process. Some cortical cells respond to lines in specific orientations (ex horixontal) Other cells in cortex: spirals, bulls-eyes, faces (prosal pognosia- not knowing faces, know people by smells and their walk and their voice)
