Document Summary

Diff wavelengths stimulate photoreceptors in eye and cause them to send a signal to brain. Transduction: conversion, one form of info is converted into another form. For seeing, light energy converted into neural code brain can understand. Hairs in ear cilia, which bend from sound waves, they are the transducers in ear. Echoic short term auditory memory talking about later on in course. Contaterality: photo receptors on right side of eyeball send signal to right hemisphere b/c are sensitive to images on left side. Both camera and eye have lense, the image is projected to back of eyeball and is inverted. Pupil is just a hole that is made by our iris, gets bigger /smaller. Optic nerve has to leave inside of eyeball somewhere gives us blindspot: hole in back our eye. Photoreceptors: rods and cones embedded in back of eyeball.
