Document Summary

Week four psyc*1000 introduction to psychology september 29th. Gather light and change it into an action potential.

Dilates (expands) to allow more light to enter. Red to green, yellow to blue, and white to black. Common visual disorders: colour blindness, nearsightedness, myopia, farsightedness, prosopagnosia face-blindness (condition is the inability to recognize faces) Several parallel pathways (streams: parallel: each stream does its processing independently and simultaneously. Each stream is hierarchically-organized: hierarchy: each stage in the stream does its processing before sending to it away, everything that happens on the left side of the world gets processed through right. Thalamocortical pathway (most important pathway: eye (retina, thalamus (lateral geniculate nucleus, cortex (primary visual cortex, hierarchical: each successive stage does more advanced processing of info that is received from the preceding stage.
