Correct tonotopic representation is necessary for complex pitch perception.
The ability to extract a pitch from complex harmonic sounds, such as human speech, animal vocalizations, and musical instruments, is a fundamental attribute of hearing. Some theories of pitch rely on the frequency-to-place mapping, or tonotopy, in the inner ear (cochlea), but most current models are based solely on the relative timing of spikes in the auditory nerve. So far, it has proved to be...
متن کاملTonotopic cortical representation of periodic complex sounds.
Most of the sounds that are biologically relevant are complex periodic sounds, i.e., they are made up of harmonics, whose frequencies are integer multiples of a fundamental frequency (Fo). The Fo of a complex sound can be varied by modifying its periodicity frequency; these variations are perceived as the pitch of the voice or as the note of a musical instrument. The center frequency (CF) of pe...
متن کاملTopographic organization is essential for pitch perception.
P itch is the perceptual attribute we associate most with melodies in music, patterns of bird songs, and the distinctions between speakers’ voices. It plays a key role in the organization, segregation, and identification of sound sources in cluttered auditory scenes because it is derived from acoustic cues that closely reflect the material and geometric properties of resonating objects. Pitch h...

متن کاملPitch Perception of Complex Sounds: Nonlinearity Revisited
The ability of the auditory system to perceive the fundamental frequency of a sound even when this frequency is removed from the stimulus is an interesting phenomenon related to the pitch of complex sounds. This capability is known as “residue” or “virtual pitch” perception and was first reported last century in the pioneering work of Seebeck. It is residue perception that allows one to listen ...
