Neurophysiological evidence confirms that spinal reflex circuits and local interneuron networks process sensory-motor information directly within the spinal cord without requiring immediate brain involvement.
The claim states that reflex arc neurons process information locally without brain involvement. Papers discussing spinal cord circuits (such as 8 and 11) directly support the physiological fact that reflex arcs and central pattern generators within the spinal cord process local inputs and generate motor outputs independently of higher brain centers.
