PSY 110 Lecture Notes - Lecture 1: Action Potential, Color Blindness, Color Vision
Document Summary
This translation is necessary because the nerve cells in your brain respond to the activity of nerve cells (not light, sound, smells, etc. ) There are two kinds of photoreceptors in your eye. Cones are located mostly on the middle of the retina and rods are located throughout the retina. How are photo receptors relevant to real world behavior: cones help you see during the day. Color blindness is generally due to a problem with cone cells: rods help you see at night. Dark adaptation is a process by you gradually see better: the optic nerve connects the eye to the brain. The optic nerve carries the nerve signal to the brain: the visual cortex receives and interrupts, the auditory system. The outer and middle ear collects and modifies the stimulation. The main job of the sense systems is to deliver info from the world to the brain. Distal stimulus info in the world proximal stimulus info in the brain.
