Faces are a primary source of social information, but little is known about the sequence of neural processing of personally relevant faces, such as those of our loved ones.

We applied representational similarity analyses to EEG-fMRI measurement of neural responses to faces of personal relevance to participants – their romantic partner and a friend – compared to a stranger. Faces expressed fear, happiness or no emotion. […]

Models of face processing postulate that recognition of face identity takes place with structural encoding in the fusiform gyrus around 170 ms after stimulus onset. We provide evidence that the high personal relevance of our friends’ and loved ones’ faces is detected prior to structural encoding […] as early as 100 ms after stimulus onset. […] Our findings imply that our brain can ‘bypass’ full structural encoding of face identity in order to prioritise the processing of faces most relevant to us.
