Somewhere between the moment a creature moves and the moment it perceives, the brain must answer an ancient question: was that the world, or was that me? Researchers at Washington University in St. Louis have identified a small cluster of neurons — the mesencephalic command-associated nucleus, or MCA — as the central timing hub through which the brain coordinates its predictions about self-generated sensation. Discovered through the elegant sensory lives of weakly electric fish, this finding suggests that evolution, rather than reinventing the wheel across species and lifetimes, quietly adjust
