Suppl. Fig.1. Variability in caudal superior temporal sulcus.
Coronal MR anatomical sections from 4 monkeys (M1, M3, M4 and M5) showing the variability in the caudal superior temporal sulcus, indicated with the white arrows. The sulcus indicated with the white arrow is more pronounced in M3 and M4 (top) than in M1 and M5 (bottom).

Suppl. Fig. 2 Motion responsive regions within the STS. Amplitude maps (percent MR signal change) for five motion contrasts: slow moving (1 deg/s) random textured patterns compared to static control (A, B); fast moving (16 deg/s) random textured patterns compared to static control (C, D); expanding and contracting random dot patterns compared to static control (E, F) ; rotating random dot patterns compared to static control (G, H) and translating random dot patterns compared to static control (I, J). Contrasts are indicated: SS: slow speed, ST static, FS: fast speed, EC: expansion/contraction, RO: rotation, TR: translation. Red circles indicate SPM local maxima. 1,2,3 indicate local maxima of MT/V5, MSTv and FST respectively, following Vanduffel et al (2001). A: anterior, D: dorsal, P: posterior, V: ventral. Colors indicate different intervals of percent MR signal change (see colorbars). Data are derived from group analysis of three monkeys (M1, M4, M5).

Suppl. Fig. 3 Time course of MR signals in the mixed and adapted motion blocks of the direction adaptation test in MT/V5 (A), MSTv (B), MSTd (C), FST (D), LST (E), STPm (F). Peripheral stimulus (5 degree eccentricity, data monkey M6). Same conventions as in Fig. 8. The differences in MR signals between mixed and adapted blocks (last 8 values of three middle blocks) was significant (paired t-test, one tailed) in all six regions, at the corrected level in MT/V5, MSTv, MSTd, FST, STP and at uncorrected level in LST. The difference was not significant in V4 nor in V3A.

Suppl. Fig. 4. Action test in passive and active conditions. A: single frame for middle of the action video with indication of fixation point (left) and central oriented bar (right). B: Percent MR signal change (relative to fixation) in the three conditions and two task contexts in the six motion regions. Data from one monkey (M5). Same convention as Fig. 9. The effect of conditions (one-way ANOVA) was significant (p<0.000001) in MT/V5, FST, LST and STPm both under passive and active conditions, as it was in MSTd (p<0.001).

Suppl. Fig 5. Schematic representation of the six motion sensitive STS regions (see colored labels) and the two pathways originating from MT/V5. Major functional sensitivities are indicated by icons. The inset indicates location of left STS in the macaque brain.
