The signer and the sign: cortical correlates of person identity and language processing from point-light displays.

Campbell R, Capek CM, Gazarian K, MacSweeney M, Woll B, David AS, McGuire PK, Brammer MJ - Neuropsychologia (2011)

Bottom Line: This activation may reflect the recruitment of information about person identity from the reduced display.Signer identification elicited greater activation than sign identification in (bilateral) inferior temporal gyri (BA 37/19), fusiform gyri (BA 37), middle and posterior portions of the middle temporal gyri (BAs 37 and 19), and superior temporal gyri (BA 22 and 42).Inferior temporal regions associated with the visual recognition of a person appear to be required during SL processing, for both carrier and content information.

Regions showing significant activation: person identification (PI) greater than sign identification (SI) are in red/yellow, SI greater than PI are in blue/green; six axial sections, are displayed; the left hemisphere is displayed on the left; regions labeled: fusiform gyrus (FG), posterior superior temporal sulcus (STS-p), inferior frontal gyrus (IFG) and precuneus (PCu); voxelwise p value = 0.05, cluster-wise p-value = 0.005.

Mentions: Having covaried for PI behavioural scores (see Section 2), ANOVA was used to compare the two experimental conditions (>the motion baseline). Clusters showing greater activation for PI than SI were focused in the inferior temporal gyri of each hemisphere (BA 37/19) and included the fusiform gyri (BA 37) and middle and posterior portions of the middle temporal gyri (BAs 37 and 19), and the superior temporal gyri (BAs 22 and 42). These clusters also extended superiorly into the supramarginal gyri (BA 40) and posteriorly into the middle occipital gyri. The right hemisphere cluster also extended into the lingual gyrus (BA 19) and cuneus (BA 17/18) whereas the left hemisphere cluster extended into the lateral portion of the transverse temporal gyrus (BA 41). An additional cluster was focused in the right middle frontal gyrus (BA 9). This extended dorsally to BA 8 and precentral gyrus (BA 6) and ventrally to DLPFC (BA 46) and the inferior frontal gyrus (BAs 44 and 45) (Fig. 2 and Table 1).
