adjustment of the pupil of the eye to light variations; the property by which a neuron relays a decreased frequency of action potentials from a stimulus of constant size; decrease in perception of sensation with continued stimulation
Decline in response of sensory receptor to maintained stimulus. Some receptors adapt quickly, e.g. Pacinian corpuscle; others slowly, e.g. baroreceptors.
The process by which the sensitivity to a stimulus declines if the stimulus is continually presented.
The process by which the sensitivity to a particular stimulus declines when it is continually presented.
is defined as the decline in response of a sensory receptor to a continual steady stimulus
Decline in the amplitude of a sensory response in the prescence of a constant stimulus
Induction or repression of synthesis of a macromolecule (usually a protein) in response to a stimulus, e.g. enzyme adaptation - an alteration in enzyme activity brought about by an inducer or repressor and involving an altered rate of enzyme synthesis or degradation.
Decrease in sensory response when the stimulus is held constant
The process of adjustment to a specific stimulus.
a condition in which the brain no longer perceives the available stimuli because the receptors are not picking up enough stimuli or are picking up too much of the same stimulus.
Attenuation of response to a sustained sensory stimulus ( Ch. 9).
