Structure-function associations in medial temporal lobe reflect specialised, behaviourally-relevant neurocognitive circuits for the perception of faces and places.
A distinct cortical region serves head gaze following, and is needed to establish joint attention with others and to ultimately develop a theory of others' mind.
Diverse photographs of human faces against their natural background trigger a specific electrical response in the right hemisphere of the brain in infants aged 4–6 months.
Conscious visual percepts are encoded by face patches in the absence of report, can be decoded from population recordings, and are multiplexed with the veridical physical stimulus.
Both bottom-up and top-down processing are involved in the occipital-temporal face network, with the top-down modulation more extensively engaged when available information is sparse in the face images.
Consistent spatial clustering and fine-scale neural tuning to different face parts were found within the face-processing regions, which may be the neural implementation of efficient neural computation for face identification.
A combination of human imaging and brain stimulation techniques show that the somatosensory cortex is essential to prosocial decision making, by transforming observed pain in accurate perception of others' distress.
Contrasting with neural network theories, a study of the cross-species perception of dynamic faces with highly realistic human and monkey avatars reveals independent perceptual encoding of facial shape and expression.

It is possible to account for efficient facial expression recognition without having to invoke a mechanism of motor simulation, even in very sensitive and challenging tasks.
