Neural representations of faces and body parts in macaque and human cortex: a comparative FMRI study - PubMed (original) (raw)

Face-selective representations in monkey temporal cortex. A: activation maps in monkeys M1 through M3 depicting areas activated significantly more by faces compared with objects (P < 0.01, uncorrected for multiple comparisons) projected onto flattened cortical surfaces. Color scale bar indicates F-score values of functional activity in colored areas. Areas in temporal cortex found in at least 2 of the 3 monkeys are labeled as regions of interest (ROIs; i.e., ML, MF, AL, AF, AD). B: ROIs of monkeys M1 through M3 (M1 = red, M2 = blue, M3 = green) projected onto the standardized surface of a single monkey (M3). Dotted ovals encircle each ROI. C: mean signal changes from 5 ROIs averaged across the 3 monkeys. Vertical error bars denote the SE. Abbreviations above each bar denote significant differences (P < 0.05) between faces, body parts, foods, and scenes with matched paired _t_-test. Mean signal change for the objects condition is shown within gray bar as a reference (see

methods

). D: selectivity indices from each area. Selectivity of each area to faces (black) and body parts (white) relative to the foods, objects, and scenes, computed with an index (see

methods

). LH, left hemisphere; RH, right hemisphere; ML, middle lateral; MF, middle fundus; AL, anterior lateral; AF, anterior fundus; AD, anterior dorsal; sf, sylvian fissure; sts, superior temporal sulcus; ios, inferior occipital sulcus; ots, occipital temporal sulcus; amts, anterior middle temporal sulcus; fa, face condition; bp, body part condition; fd, food condition; ob, object condition; sc, scene condition.
