2-Minute Neuroscience: Cochlea

June 19, 2015


In this video, I discuss the cochlea. I describe the passage of sound waves through the ear, which leads to the depression of the oval window, a structure found in the wall of the cochlea. I cover the three main cavities in the cochlea: the scala vestibuli, scala media, and scala tympani. Then I describe how the movement of fluid in the cochlea causes movement of the basilar membrane, which activates hair cells in the organ of Corti. The hair cells transmit the auditory information to the vestibulocochlear nerve, which carries it to the brain to be processed.
