Social hierarchies exist in all societies and cultures. In this lesson, we define

BASIC STRUCTURE OF NERVE CELLS ("NEURONS") "Swiftly the brain becomes an enchanted loom, where millions of flashing shuttles weave a dissolving pattern-always a meaningful pattern-though never an abiding one" (Sherrington, 1940).
