nada M 2004Over the past decade, animal studies provided shed insight into the functional organization of the auditory system. Single-cell recordings and neuroanatomical tracer studies on nonhuman pri-mates have described a primary auditory cortex that is surrounded by a ‘belt ’ area, which is in turn bordered laterally by a ‘parabelt’ region (Hackett et al., 1998; Kosaki et al., 1997; Morel et al., 1993; previous study (Alain et al., 2001), processing the location of noise bursts elicited relatively greater parietal and superior prefrontal activity than did processing the pitch of the noise bursts. In contrast, pitch processing resulted in relatively greater superior temporal and inferior frontal activity. Such results, in conjunction with human lesion data (Clarke et al., 2000; Thiran and Clarke, 2003), are consistent with the proposal that the human auditory system can be functionally segregated into ‘‘what’ ’ and ‘‘where’ ’ pathways.Keywords: Auditory scene analysis; fMRI; Meta-analysis; Nonspatial; PET
