New Research Discovers How Our Brain Identifies Familiar Faces

In a recent study published in "Proceedings of the National Academy of Sciences", it was found that the information about familiar faces is recorded in a neural code and shared across brains. Researchers used hyperalignment, which generates a shared representational space to analyze how individuals' brain activity is comparable. Data from three fMRI tasks involving 14 students who'd known each other for two years was used by researchers.
