Research overview: cochlear tonotopy and high-frequency representation

Inside the cat cochlea, different frequencies stimulate different positions along the basilar membrane, and this overview reviews this tonotopic organisation and its high-frequency emphasis. The cochlea maps pitch onto place, with a substantial portion devoted to the high and ultrasonic frequencies cats use to detect small prey, and this map is preserved into the auditory brain. The feline cochlea has been a foundational preparation in auditory neuroscience. Researchers study tonotopy through electrophysiology and anatomy. Why it matters: tonotopic mapping is fundamental to how mammals analyse sound, and the cat extended high-frequency representation reflects its predatory hearing needs. Decades of work on the feline auditory system have shaped understanding of hearing in general, including the principles behind cochlear implants, making the cat ear a landmark model organ.
