Brain’s Response to Familiar Faces Draws on Shared Neural Code for...

A new study from Dartmouth College used between-subject linear classifiers trained on hyperaligned brain fMRI data to investigate the neural code for visual and semantic information required for the brain’s ability to process familiar faces. The authors showed the identity of both visually and personally familiar faces can be decoded across participants from brain activity in visual areas of the brain but only the identity of personally familiar faces can be decoded in areas involved in social cognition.
