Sound hits tympanic membrane which vibrates “ vibrates stapes or columnella w vibrates oval window & causes waves in internal fluid & bends hair cells & sends impulses to brain. Birds hear within the same range as humans. When the impulses get to the brain, they must be decoded. This is done by the anterior forebrain pathway: Includes three main auditory centers that respond to sound: DLM, Field L, and LMAN These centers have neurons that respond to different aspects of sound. The signals from the different neurons within the nuclei paint a picture of the sound. Then, signals are sent to the other nuclei in the brain that have different functions. HVC, RA, and nXIIts – motor DLM, Field L, and LMAN – auditory centers Area X – song memory/crystallization....
