Scientists Discover a Face-Detection Circuit in The Brains of Primates

The Best in Science News and Amazing Breakthroughs

Primates can detect faces out of the corner of their eyes with incredible speed via a newly discovered brain circuit.) catch something in their peripheral vision, the blurry mess is categorized as a face or an object in under 40 milliseconds, even before the animals turn their gaze to, which travels from the eyes to an early part of the visual cortex and onto a part of the midbrain.

In experiments, researchers at the NIH scanned the brains of two macaques to see which neurons activated when the animals were shown images of monkey faces, human faces, bodies, hands, fruits or vegetables, or human-made objects. When the results were pooled, the team found that both monkeys could discriminate between faces and non-faces just 30 milliseconds after an image was shown. By 50 milliseconds, that discrimination had reached 80 percent accuracy, and at 90 milliseconds, accuracy peaked at 92 percent.
