[Changes in efferent activity in the renal and splenic nerves during stimulation of the bulbar reticular nucleus]

Acute experiments on cats have shown that stimulation of the paramedian and ventricular reticular nuclei produces clear-cut and consistent changes in efferent activity of renal and splenic nerves. These changes are far more pronounced after ventricular nucleus stimulation. The changes in sympathetic activity and SAD after stimulation of the nuclei were inconclusive, thus indicating a diffuse distribution of pressor and depressor neurons in these nuclei. Acetylcholine microinjections into the ventricular reticular nucleus was accompanied by more marked changes in the activity of the splenic nerve, whereas stimulation of the paramedian reticular nucleus affected to a greater measure the renal nerve.
