Document Summary

The retina is a made up of layers of cells. Photoreceptors are specialised for transforming light energy into an electrical signal (rods and cones) Progressive improvement in brightness sensitivity over time in low light conditions. Rods are insensitive to wavelengths in the red spectrum. The colour we perceive depends on the __________ of light. Cones contain 1 of 3 pigment types and are most sensitive to either ____, _______ and ______ wavelengths: objects selectively _______ some wavelengths of light and _______ others. Loudness: high amplitude = hair cells ____________ = release more nt. Some hair cells have a higher ___________ for releasing nts: pitch, __________ theory: frequency of ______________ match frequency of sound, _____ theory: _______ of hair cells firing determine frequency of sound. Chapter 3: partitioning of cognitive functions preferentially into one hemisphere, language processing, handedness, why lateralized, improved processing speed; dual task attention.
