In Sensory Adaptation, the Frequency of Action Potentials _______

Question

In sensory adaptation, the frequency of action potentials _______.
A) decreases in a sensory neuron even though the stimulus is maintained
B) increases in a sensory neuron even though the stimulus is maintained
C) remains constant in a sensory neuron even though the stimulus is maintained
D) decreases in a sensory neuron even though the stimulus is increased

Accepted Answer

Sensory adaptation occurs when the frequency of action potentials decreases in a sensory neuron even though the stimulus is maintained at a constant intensity. This allows our sensory systems to filter out constant background stimuli and focus on changes and new information in the environment.
