Key result
Acute spinal transection in rats reduced arterial pressure and lumbar sympathetic activity, but doubled renal and splenogastric sympathetic activities.
Why the study?
Does acute spinal transection alter regional sympathetic nerve activities in rats?
Does acute spinal transection alter regional sympathetic nerve activities in rats?
Spinal systems in rats can maintain renal and splenogastric, but not lumbar, sympathetic activities after spinal transection, indicating independent generation of these activities.

Differential sympathetic responses after spinal transection in rats; hypothesis-generating for regional spinal autonomy, with no immediate clinical implications.
Taylor et al. (1987) studied this question. Acute spinal transection vs. Intact state (pre-transection) was evaluated on Renal, splenogastric, and lumbar multiunit sympathetic activities. Acute spinal transection in rats reduced arterial pressure and lumbar sympathetic activity, but doubled renal and splenogastric sympathetic activities.
