Have You Seen That Face Before?

The video explores how our brains recognize familiar faces, a complex process involving memory and perception. It discusses the 'grandmother neuron' hypothesis, which suggests specific neurons are responsible for recognizing familiar individuals. Although initially a joke, research has shown some support for this idea. Recent studies, including those on macaques, have identified brain regions that respond to familiar faces, suggesting a link between perception and memory. This research enhances our understanding of social interactions and brain function.
