Physiology of Motivated Behaviors
Depolarization is a process in which a neuron's membrane potential becomes less negative (or more positive) than its resting potential, typically resulting from the influx of sodium ions (Na+) into the cell. This shift in membrane potential is crucial for the generation and propagation of action potentials, which are essential for neuronal communication and signaling. The process plays a key role in various physiological functions, including muscle contraction and the transmission of signals across synapses.
congrats on reading the definition of depolarization. now let's actually learn it.
