Organization by frequency tonotopy is one of the central organizing principles of the auditory systemThe inferior colliculus IC is the primary auditory midbrain structure that forms a major convergence zone within the auditory system receiving obligatory bottom-up connections from the brainstem auditory structures and direct corticofugal feedback connections from auditory. Definition of Tonotopic Organization. This ordering begins inside the Sign in. The tonotopic progression can be described as a logarithmic mapping. Here we begin a discussion of the bats auditory system based upon three chief organizational features. Tonotopic organization of the human auditory cortex.

Such properties are frequency of tones frequency ratios between harmonics and the pitch of complex sounds speed and direction of frequency sweeps sound intensity and location of sound in space.

Tones close to each other frequency are represented in topologically near regions in the brain. Subjects were presented with stochastically alternating multi-tone sequences in six different frequency bands centered at 200 400 800 1600 3200 and 6400 Hz. The location of discrete regions of relatively high 2-DG uptake varied systematically with stimulus frequency. The primary factors of cochlear frequency tuning are generally ascribed to the passive physical characteristics of the basilar membrane BM which OP already identified in the question - The BM is wider and more flexible at the apical end low-frequency region and narrower and stiffer at the basal end high-frequency region. The frequency tuning in the cochlea is due to a number of factors. The first is that the dominant feature of the system is a tonotopic organization a remapping of the cochlear surface upon most of the nuclear groups of the primary auditory pathway.

Neuromagnetic measurements showed that the tonotopic organization of the primary auditory cortex reflects the pitch rather than the frequency of the stimulus. Tonotopic organization of the human auditory cortex. Neuromagnetic measurements of responses to auditory stimuli consisting of pure tones amplitude-modulated at a low frequency have been used to deduce the location of cortical activity. Tonotopic organization has been identified in human auditory cortex using a variety of imaging techniques. Tonotopic organization expresses gradients in the representation maps of sound properties.
