The newly discovered circuit first activates a specific part of the brain known as the superior colliculus, which then causes the eyes and head to turn to look more closely. This allows different areas of the brain in the temporal lobe to recognize more complex facial features. The study was published in the journal Neuron.
In adult primates, the brain develops special areas in the temporal lobe called “face areas” that allow people to be recognized and distinguished based on facial features. But face recognition requires high visual acuity; to recognize a face, you must first look at it directly.
