  • Overall, the results suggest that tonotopic mismatch may affect performance of CI users in complex listening environments.

  • Most previous fMRI studies of tonotopic organization have not examined the effect of sound intensity on frequency maps.

  • In contrast, fMRI studies of the tonotopic organization of human auditory cortex have typically imaged subjects in a single experimental session on activations in auditory cortex, the influence of these variables on tonotopic and non-tonotopic ACFs is not yet fully understood.

  • Studies of tonotopic organization have revealed that the anatomical locations of frequency-specific regions have a coarse but consistent relationship to local anatomical landmarks in individual subjects

  • They found evidence for two mirror-symmetric tonotopic maps encompassing the aforementioned three frequency-specific regions - the first connected a high-frequency region in HS with a low-frequency region in mid-HG and the second connected the same low-frequency region with a high-frequency region near the junction of HG and the superior temporal gyrus (STG).

  • Although most whole-brain studies have suggested that the two hemispheres differ in tonotopic organization, the results are inconsistent.

  • The basilar membrane of the inner ear contains hair cells that are frequency selective, firing only in response to a certain band of frequencies. These are stretched out across the membrane from low frequencies to high; low-frequency sounds excite hair cells on one end of the basilar membrane, medium frequency sounds excite the hair cells in the middle, and high-frequency sounds excite them at the other end. . . . Because the different tones are spread out across the surface topography of the membrane, this is called a tonotopic map.
