Final answer:
The activity of a central pattern generator can be modified by sensory feedback.
Step-by-step explanation:
The statement is True. The activity of a central pattern generator can indeed be modified by sensory feedback. Central pattern generators (CPGs) are neural circuits that generate rhythmic patterns of motor activity, such as walking or swimming, without the need for continuous input from the brain. They can be found in various organisms, including humans. Sensory feedback refers to the information received from sensory receptors in response to stimuli. This sensory information can influence and modulate the activity of the central pattern generator. For example, if you stumble while walking, the sensory feedback from your feet and legs can quickly modify the activity of the central pattern generator, resulting in adjustments to your gait to regain balance.
