Figure 1.

Experimental paradigm and behavioral results. (A) Monkeys were trained to perform a two-alternative forced-choice body/non-body categorization task. The stimulus set contained 720 photographs of body and non-body images, in four different signal levels, and 90 full-noise stimuli. For illustration only, stimulus is depicted here with a relatively large size compared to the monitor screen. Numbers represent the duration of each epoch. (B) Monkeys' performance. Images on the X-axis are examples of noisy stimuli in different signal levels. The error bars represent the ±1 standard error of the mean (s.e.m.) across recording sessions (n = 61). (C) Sagittal section of the MRI at the anteroposterior level of 16 in monkey 1. Red lines depict the boundaries of recording area (lower bank of STS and TE). White vertical line schematically represents the inserted electrode.
