Short time scale interactions between brain stem neurons with sympathetic nerve-related activity

Cross-correlation analysis revealed short time scale (ms) interactions between closely adjacent cat brain stem neurons with sympathetic nerve-related activity. The incidence of such interactions was significantly greater for reticular neurons than for raphe neurons. Shared input and/or interconnection via mono- or oligosynaptic pathways are considered as mechanisms for synchronization of the discharges of elements of the brain stem network which controls sympathetic nerve activity.
