Figure 1.
A simplified rendering of the anatomical parcellation of the STS based on the study by Seltzer and Pandya (1978). Unimodal regions are color-coded (green, auditory; blue, visual; yellow, somatosensory), and regions containing neurons that respond to more than one modality (multimodal regions) are colored in orange. The two transparent planes in the figure represent the approximate rostral and caudal boundaries of the recording area in the study by Dahl et al. (2009), which encompasses midportions of TPO. Left, A bottom-up view of the upper bank of the STS (regions shown: TAa, TPO-1, TPO-2, TPO-3, TPO-4, PGa) in which the multisensory nature of this region is clearly observed. Right, A top-down view of the lower bank of the STS (regions shown: PGa, IPa, TEa, OAa, TEm, Oa). STG, Superior temporal gyrus; MTG, middle temporal gyrus.
