Explain adaptation, and differentiate between peripheral adaptation and central adaptation
A) Adaptation is an increase in receptor sensitivity in the presence of constant stimulation. Peripheral adaptation reduces the amount of information sent to the CNS. In central adaptation, the awareness of the stimulus virtually disappears. B) Adaptation is a decrease in receptor sensitivity in the presence of constant stimulation. Peripheral adaptation reduces the amount of information sent to the CNS. In central adaptation, the awareness of the stimulus virtually disappears. C) Adaptation is an increase in receptor sensitivity in the presence of constant stimulation. Peripheral adaptation increases the amount of information sent to the CNS. In central adaptation, the awareness of the stimulus is enhanced. D) Adaptation is a decrease in receptor sensitivity in the presence of constant stimulation. Peripheral adaptation increases the amount of information sent to the CNS. In central adaptation, the awareness of the stimulus is enhanced.
