A local potential

A) does not occur until threshold.
B) transmits information from one cell to another.
C) might be a depolarization event but cannot be a hyperpolarization event.
D) increases or decreases in direct proportion to the stimulus strength.
E) does not alter resting membrane potential.

Local Potential

Small changes in membrane potential that are crucial in the propagation of nerve impulses and can lead to an action potential if they reach a certain threshold.

Depolarization Event

A temporary change in a cell's membrane potential, making it more positive, typically associated with the initiation of nerve impulses or muscle contractions.

Stimulus Strength

The intensity of a stimulus, which can influence the magnitude of response in sensory and other physiological systems.

  • Elucidate the operational principles of action potentials and local potentials.

Final Answer :
D
Explanation :
Local potentials vary in magnitude (increase or decrease) directly in proportion to the strength of the stimulus, unlike action potentials which are all-or-nothing responses once the threshold is reached.
