For generations, the neuron has been imagined as a single voice speaking one word at a time — input, computation, output. New research from the University of Texas Southwestern now reveals that the branching arms of neurons, called dendrites, hold their own counsel, storing memories and anticipating futures independently of the cell body they serve. In mouse hippocampi navigating virtual worlds, distal dendrites learned new environments before the soma even registered the change, suggesting that what we call a 'neuron' may in fact be a small democracy of semi-autonomous learners. The implicati
