Auditory Frequency Mapping

The cochlea's structure plays a crucial role in how we perceive sound frequencies, with the basilar membrane varying in width and flexibility along its length. This variation allows hair cells at different locations to respond optimally to specific frequencies, creating a tonotopic map that is mirrored in the auditory cortex. The relationship between the physical properties of the basilar membrane and the activation of hair cells is fundamental to our understanding of sound perception.
