Only a few hundreds neurons help the brain recognize faces

Doris Tsao / Caltech

Researchers believe they've cracked the code for how primates are able to recognize faces. And, it may be relatively simple: only 200 neurons or so in the brain appear to be responsible for the ability of macaque monkeys to identify the faces of humans that they know over those of complete strangers.

Why it matters: Humans and other primates are thought to use a similar face recognition system, so understanding how images are encoded by the neurons could inform the development of artificial vision.
