Physiology of Motivated Behaviors
Resting potential refers to the electrical charge difference across a neuron's plasma membrane when it is not actively transmitting a signal. This state is typically around -70 mV and is crucial for the generation of action potentials, as it establishes the conditions necessary for neurons to respond to stimuli. The resting potential is maintained by the movement of ions, particularly sodium (Na+) and potassium (K+), through ion channels and pumps, which are essential for neuronal excitability and communication.
