We compared sympathetic and circulatory responses between kidney and skeletal muscles during fictive locomotion evoked by electrical stimulation of the mesencephalic locomotor region (MLR) in decerebrate and paralyzed rats (n = 8). Stimulation of the MLR for 30 s at 40-microA current intensity significantly increased arterial pressure (+38 +/- 6 mmHg), triceps surae muscle blood flow (+17 +/- 3%), and both renal and lumbar sympathetic nerve activities (RSNA +113 +/- 16%, LSNA +31 +/- 7%). The… CONTINUE READING
