040 The Role of Hair Cells in Hearing

In this episode, Leslie Samuel explores the role of hair cells in hearing. The video begins with a recap of the cochlea's function and the basilar membrane's response to sound. It then delves into the specific role of inner hair cells, explaining how they transmit signals to the brain. The mechanics of hair cells, including the function of stereocilia and potassium channels, are discussed. The video also covers how potassium and calcium ions influence membrane potential, leading to neurotransmitter release. The episode concludes with a summary of how these processes connect to the auditory nerve and hearing.
