“…Given the variability in the number of folds of Heschl's gyri [Campain and Minckler, 1976] and the gross morphological differences in the left and right supratemporal planes of humans [Galaburda et al, 1978], it might be the case that a tonotopic pattern was more obstructed by overlapping mirror-image maps in the right than the left hemisphere. Because previous reports of tonotopic organization in humans have often used monaural stimulus presentations [Yamamoto et al, 1992;Pantev et al, 1994;Tiitinen et al, 1993;Huotilainen et al, 1995;Verkindt et al, 1995], they were unable to fully evaluate any left-right asymmetry. Finally, a similar left-hemisphere tonotopic predominance was also revealed by Lauter et al [1985] using PET.…”

Tonotopic organization within the human auditory cortex was investigated with functional magnetic resonance imaging (fMRI) using the blood oxygenation level-dependent (BOLD) contrast mechanism. Single-frequency pulsed tones were alternated with no-tone conditions to elicit stimulus-specific functional activity. Differential frequency-specific activity was imaged within the auditory cortex Activations for high-frequency tones were located more posteriorly and medially than those for low-frequency tones. Such a pattern is consistent with descriptions of tonotopic organization suggested by other nonneuroimaging methodologies used with human and nonhuman primates. Furthermore, these results demonstrate that fMRI can be used to reliably investigate functional organization of the human auditory cortex. Hum. Brain Mapping 4:18-25, 1997. (c) 1997 Wiley-Liss, Inc.

“…We do know from studies in humans that a tonotopic pattern of organization can be revealed crudely in the region of the core. A variety of studies using evoked potentials (39,40), magnetoencephalography (41)(42)(43)(44)(45)(46)(47)(48)(49)(50)(51)(52), positron emission tomography (53)(54)(55)(56), and functional magnetic resonance imaging (57-60) have produced convincing evidence of tonotopic organization in the human transverse temporal gyrus of Heschl (TTG). As observed in monkeys, high frequencies are represented in the posteromedial TTG of humans, whereas lower frequencies generate activity in anterolateral TTG.…”

The auditory system of monkeys includes a large number of interconnected subcortical nuclei and cortical areas. At subcortical levels, the structural components of the auditory system of monkeys resemble those of nonprimates, but the organization at cortical levels is different. In monkeys, the ventral nucleus of the medial geniculate complex projects in parallel to a core of three primary-like auditory areas, AI, R, and RT, constituting the first stage of cortical processing. These areas interconnect and project to the homotopic and other locations in the opposite cerebral hemisphere and to a surrounding array of eight proposed belt areas as a second stage of cortical processing. The belt areas in turn project in overlapping patterns to a lateral parabelt region with at least rostral and caudal subdivisions as a third stage of cortical processing. The divisions of the parabelt distribute to adjoining auditory and multimodal regions of the temporal lobe and to four functionally distinct regions of the frontal lobe. Histochemically, chimpanzees and humans have an auditory core that closely resembles that of monkeys. The challenge for future researchers is to understand how this complex system in monkeys analyzes and utilizes auditory information.

“…Using electrodes implanted in epileptic patients to detect the foci of seizures, a lateral progression in frequency sensitivity from high frequency (3360 Hz) to lower frequency (1480 Hz) has been found [Howard et al, 1996]. Using MEG and EEG, a systematic relationship has been shown between dipole sources and stimulus frequency in the auditory cortex [e.g., Romani et al, 1982aRomani et al, , 1982bPantev et al, 1988Pantev et al, , 1995Yamamoto et al, 1992;Huotilainen et al, 1995;Lütkenhöner and Steinsträter, 1998;Rosburg et al, 2000]. Lütkenhöner and Steinsträter [1998] demonstrated a lateral shift in the location of the response within HG as tone frequency was presented at Fig.…”

The human auditory cortex comprises multiple areas, largely distributed across the supratemporal plane, but the precise number and configuration of auditory areas and their functional significance have not yet been clearly established. In this paper, we discuss recent research concerning architectonic and functional organisation within the human auditory cortex, as well as architectonic and neurophysiological studies in non-human species, which can provide a broad conceptual framework for interpreting functional specialisation in humans. We review the pattern in human auditory cortex of the functional responses to various acoustic cues, such as frequency, pitch, sound level, temporal variation, motion and spatial location, and we discuss their correspondence to what is known about the organisation of the auditory cortex in other primates. There is some neuroimaging evidence of multiple tonotopically organised fields in humans and of functional specialisations of the fields in the processing of different sound features. It is thought that the primary area, on Heschl’s gyrus, may have a larger involvement in processing basic sound features, such as frequency and level, and that posterior non-primary areas on the planum temporale may play a larger role in processing more spectrotemporally complex sounds. Ways in which current knowledge of auditory cortical organisation and different data analysis approaches may benefit future functional neuroimaging studies which seek to link auditory cortical structure and function are discussed.
