Tracing Sound to the Auditory Cortex

This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.

State

Tracing hearing means following a pressure wave from outer ear to eardrum to ossicles to cochlea to hair cells to thalamus to temporal cortex.

Show

One sound followed the whole distance at honest pace, including the air-to-fluid transfer that requires the middle ear, the frequency separation along the basilar membrane, the transduction at the hair cells, and the point at which frequency has become pitch. No step compressed.
