LOCAL POTENTIAL

Defining the Local Potential: The Graded Response The concept of the local potential is central to understanding the initial stages of neuronal communication within the nervous system. Unlike the regenerative, self-propagating electrical signal known as the action potential, the local potential represents a localized change in the neuron’s membrane voltage that occurs immediately following the […]

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 […]
