Differential relationships among 10-Hz rhythmic discharges of sympathetic nerves with different targets depend on supraspinal rather than spinal mechanisms.
In urethane-anesthetized cats, ordinary and partial coherence values relating the 10-Hz rhythmic discharges of sympathetic nerves located on opposite sides of the body were not significantly affected by midsagittal section of the spinal cord from the seventh cervical through eighth thoracic or first cervical through eighth cervical segments. Thus, coordination of the 10-Hz discharges of the nerves occurred at a supraspinal level.
