웹2024년 7월 7일 · The cochlea is a snail-shaped organ which has many tiny receptor hair cells embedded in a basilar membrane which respond to certain frequencies of sound. This is known as tonotopic organization in which the base of the membrane in the cochlea responds to higher pitches and the apex responds to lower pitches. 웹The basilar membrane is a key component of the inner ear responsible for converting sound vibrations into electrical signals that the brain can interpret. The membrane is lined with hair cells that are sensitive to different frequencies of sound, with higher frequency sounds causing vibrations closer to the base of the membrane and lower frequency sounds causing …
