Question

Which of the following describe a central pattern generator? Choose all that apply.
A) Functions in the absence of sensory input
B) A circuit of neurons that produces a rhythmic pattern of neural activity
C) The rhythmic contraction of opposing muscle groups
D) A group of neurons that innervate opposing muscle groups

Accepted Answer

Central pattern generators (CPGs) are neural circuits that can produce rhythmic outputs in the absence of sensory or descending inputs that carry specific timing information. They are responsible for generating the rhythmic pattern of neural activity that underlies various repetitive motions, such as walking or breathing, without requiring sensory feedback to initiate or maintain the rhythm.
