New maps of brain activity challenge century-old anatomical boundaries

New research challenges the century-old practice of mapping the brain based on how tissue looks under a microscope. By analyzing electrical signals from thousands of neurons in mice, scientists discovered that the brain’s command center organizes itself by information flow rather than physical structure. These findings appear in the journal Nature Neuroscience. The prefrontal cortex acts as the brain’s executive hub. It manages complex processes such as planning, decision-making, and reasoning. Historically, neuroscientists defined the boundaries of this region by studying cytoarchitecture. This method involves staining brain tissue and observing the arrangement of cells. The...
