“…There was an additional positive correlation in the caudate nucleus. Although the finding in the caudate nucleus is not relevant for the purpose of validation, it is of great interest considering the animal literature that suggests extensive connections between caudate nucleus and secondary auditory areas as well as auditory association cortex (Baizer et al, 1993;Yeterian and Pandya, 1998). If brain structures localized in different regions (e.g., PT and caudate nucleus) are strongly interconnected, they might resemble each other in terms of asymmetry.…”

A voxel-based approach to gray matter asymmetries

Voxel-based morphometry (VBM) was used to analyze gray matter (GM) asymmetries in a large sample (n = 60) of male and female professional musicians with and without absolute pitch (AP). We chose to examine these particular groups because previous studies using traditional region-of-interest (ROI) analyses have shown differences in hemispheric asymmetry related to AP and gender. Voxel-based methods may have advantages over traditional ROI-based methods since the analysis can be performed across the whole brain with minimal user bias. After determining that the VBM method was sufficiently sensitive for the detection of differences in GM asymmetries between groups, we found that male AP musicians were more leftward lateralized in the anterior region of the planum temporale (PT) than male non-AP musicians. This confirmed the results of previous studies using ROI-based methods that showed an association between PT asymmetry and the AP phenotype. We further observed that male non-AP musicians revealed an increased leftward GM asymmetry in the postcentral gyrus compared to female non-AP musicians, again corroborating results of a previously published study using ROI-based methods. By analyzing hemispheric GM differences across our entire sample, we were able to partially confirm findings of previous studies using traditional morphometric techniques, as well as more recent, voxel-based analyses. In addition, we found some unusually pronounced GM asymmetries in our musician sample not previously detected in subjects unselected for musical training. Since we were able to validate gender-and AP-related brain asymmetries previously described using traditional ROI-based morphometric techniques, the results of our analyses support the use of VBM for examinations of GM asymmetries.

“…A common neuroanatomical classification scheme partitions the striatum into three general regions: sensorimotor, associative, and limbic (e.g., Flaherty & Graybiel, 1993;Parent & Hazrati, 1995;Selemon & Goldman-Rakic, 1985;Yeterian & Pandya, 1995). Roughly speaking, the sensorimotor striatum includes most of the putamen, the associative striatum includes most of the caudate nucleus, and the limbic striatum includes the ventral striatum (e.g., nucleus accumbens).…”

Much recent evidence suggests that human category learning is mediated by multiple systems. Evidence suggests that at least one of these depends on procedural learning within the basal ganglia. Information-integration categorization tasks are thought to load heavily on this procedural learning system. The results of several previous studies were interpreted to suggest that response positions are learned in information-integration tasks. This hypothesis was tested in two experiments. Experiment 1 showed that information-integration category learning was slowed but not disrupted when the spatial location of the responses varied randomly across trials. Experiment 2 showed that information-integration learning was impaired if category membership was signaled by responding to a yes/no question and the category label had no consistent spatial location. These results suggest that information-integration category learning does not require consistent response locations. In these experiments, a consistent association between a category and a response feature was sufficient. The implication of these results for the neurobiology of information-integration category learning is discussed.

“…The notion that the BG play a role in the processing of emotional prosody is supported by the presence of incoming projections from the superior temporal gyrus (i.e. a region overlapping or in close proximity with the auditory cortex) to the caudate and putamen (Yeterian and Van Hoesen, 1978;Yeterian and Pandya, 1998), as well as from the MGB to the striatum and globus pallidus (Moriizumi and Hattori, 1992). Outgoing fibres from the pulvinar to the rostral superior temporal gyrus and sulcus have also been described and are thought to play a role in auditory information processing (Romanski et al, 1997).…”

Subcortical processing in auditory communication

a b s t r a c tThe voice is a rich source of information, which the human brain has evolved to decode and interpret. Empirical observations have shown that the human auditory system is especially sensitive to the human voice, and that activity within the voice-sensitive regions of the primary and secondary auditory cortex is modulated by the emotional quality of the vocal signal, and may therefore subserve, with frontal regions, the cognitive ability to correctly identify the speaker's affective state. So far, the network involved in the processing of vocal affect has been mainly characterised at the cortical level. However, anatomical and functional evidence suggests that acoustic information relevant to the affective quality of the auditory signal might be processed prior to the auditory cortex.Here we review the animal and human literature on the main subcortical structures along the auditory pathway, and propose a model whereby the distinction between different types of vocal affect in auditory communication begins at very early stages of auditory processing, and relies on the analysis of individual acoustic features of the sound signal. We further suggest that this early feature-based decoding occurs at a subcortical level along the ascending auditory pathway, and provides a preliminary coarse (but fast) characterisation of the affective quality of the auditory signal before the more refined (but slower) cortical processing is completed.
