Abdominal ganglion
The abdominal ganglia possess motor centers related to posture control, rhythmic behavior, such as respiration, and circulation and the control of copulation and egg laying. The motor centers residing in thoracic or abdominal ganglia autonomously express and correct motor patterns in response to their own local sensory inputs (trigger inputs) largely without depending on inputs from the brain. However, the initiation and maintenance of their motor patterns are generally controlled by descending interneurons from the brain.
