SUBTHRESHOLD POTENTIAL

Subthreshold Potential Introduction and Core Definition A subthreshold potential, in the field of neurophysiology, represents a localized change in the electrical charge across a neuronal or muscle cell membrane that is of insufficient magnitude to initiate a full-blown, self-propagating electrical impulse known as an action potential. This phenomenon is fundamental to understanding how the nervous […]

AMPA RECEPTOR

AMPA Receptor The Core Definition of the AMPA Receptor The AMPA receptor, often abbreviated as AMPAR, is a fundamental type of ionotropic glutamate receptor that serves as the primary mediator of fast excitatory synaptic transmission in the central nervous system. Its name is derived from the synthetic agonist used to identify it: alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA). […]
