Psychophysiology: How Electrical Signals Drive Our Actions
Introduction and Definitional Framework The Muscle Action Potential (MAP) constitutes the fundamental electrical signal essential for triggering muscle contraction across all fiber types—skeletal, cardiac, and smooth. It is defined as a rapid, transient, self-propagating wave of depolarization and subsequent repolarization that sweeps across the entire muscle cell membrane, known as the sarcolemma, immediately following adequate […]
