To perceive faces, your brain relies on a process similar to face recognition systems

Imagine if every time you looked at a face, one side of the face always appeared distorted as if it were melting, resembling a painting by Salvador Dalí. This is the case for people with hemi-prosopometamophosia (hemi-PMO). A new study finds that people with hemi-PMO see distortions to the same half of a person’s face regardless of how it is viewed. The results show how the the brain uses a process similar to computer face recognition systems to perceive faces.
