Central Adaptation Refers To

Question

Central adaptation refers to
A) the decline in activity of peripheral receptors when stimulated.
B) a characteristic of phasic receptors.
C) inhibition of nuclei located along a sensory pathway.
D) increases in conscious perception of a sensory stimulus.
E) a change in motor receptivity of a neuron.

Accepted Answer

Central adaptation refers to inhibition of nuclei located along a sensory pathway, which can decrease the ability to perceive a sensory stimulus. This is in contrast to peripheral adaptation, which refers to a decline in activity of peripheral receptors when stimulated. Phasic receptors are characterized by rapid adaptation to a stimulus. Changes in motor receptivity of a neuron and increases in conscious perception are not directly related to central adaptation.
