Discussion

Defines neural substrates of somatosympathetic reflex in rats; leaves open translation to human sympathetic control.

Population

Urethan-anesthetized, paralyzed, ventilated rats

Intervention

Single sciatic nerve stimuli

Outcome

Excitation of antidromically identified, RVL-spinal, sympathoexcitatory neurons and splanchnic nerve activitysurrogate

The rat somatosympathetic reflex consists of early and late excitatory components mediated by RVL-spinal sympathoexcitatory neurons.

Morrison et al. (1989) studied this question.
