The primate brain features specialized areas devoted to processing of faces, which human imaging studies localized in the superior temporal sulcus (STS) and ventral temporal cortex. Studies in macaque monkeys, in contrast, revealed face selectivity predominantly in the STS. While this discrepancy could result from a true species difference, it may simply be the consequence of technical difficulties in obtaining high-quality MR images from the ventral temporal lobe. By using an optimized fMRI protocol we here report face-selective areas in ventral TE, the parahippocampal cortex, the entorhinal cortex, and the hippocampus of awake macaques, in addition to those already known in the STS. Notably, the face-selective activation of these memory-related areas was observed although the animals were passively viewing and it was preserved even under anesthesia. These results point to similarly extensive cortical networks for face processing in humans and monkeys and highlight potential homologs of the human fusiform face area.

- View-tolerant face recognition and Hebbian learning imply mirror-symmetric neural tuning to head orientation (2016, neutral): “The ventral stream of the macaque brain contains discrete patches of cortex that support the processing of images of faces [52, 53, 28, 2].”
- How does the brain solve visual object recognition? (2012, neutral): “…striking illustration of this is recent monkey fMRI work, which shows that there are three (Tsao et al., 2003) to six (Tsao et al., 2008a) or more (Ku et al., 2011) smaller regions within IT that may be involved in face ‘‘processing’’ (Tsao et al., 2008b) (also see Op de Beeck et al., 2008; Pinsk…”
