PSYC 273 Lecture Notes - Lecture 1: Cochlear Nucleus, Thalamus, Timpani
Document Summary
Hearing: auditory system: detects changes in the vibration of air molecules that are caused by sound sources sensing intensity & frequency of sounds. Into neural activity: fundamental: predominant frequency of an auditory tone or a visual scene, harmonics: multiple of frequency/fundamental. The ear: pinnea: external part of the ear, funnels sound waves into external ear/ear canal, ear canal: tube leading from pinnae to tympanic membrane (cavity between tympanic membrane & cochlea) Inner ear/cochlea (converts vibrations from sound into neural activity) Scala tympani: vestiubulocochlear nerve, organ of corti, hair cells, basilar membrane. Inner hair cells: 1 of 2 types of receptor cells for hearing in the cochlea. More: basilar membrane: base of organ of corti that contains principle structures for auditory transduction. Ohc (outer hair cell) efferent: cochlear nuclei: either of the 2 brainstem nuclei hat receives input from auditory hair cells. Receives input from hair cells (vibrational energy turned into neural activity and sends to.
