Document Summary

Both are valid in part, issue with place theory = hair cells vibrate together not independently. Pattern of vibration (george von bekesy) travelling wave that moves along basilar membrane, low frequency tones are translated into pitch through frequency. Auditory localization = locating the source of a sound in space (involves spatial aspects of sensory input, 2 sensory cues: intensity/loudness and timing of sounds arriving in each ear) partial sound barrier also at work (cast by head) Music special effects on brain motor, auditory, and visuospatial areas of cerebellum. Mozart effect = music can effect our spatial abilities. Speech prosody = musical aspects of speech (innotation/melody, & stressing and timing/rhythm) Physical stimuli = chemical substances that are soluble. Receptors = clusters of taste cells in taste buds (live 10 days), line trenches around tiny bumps on tongue. Cells absorb chemicals dissolved in saliva, trigger neural impulses.
