Implication

No immediate clinical implications; hypothesis-generating for splanchnic modulation of medullary sympathetic outflow in animal models.

Structured PICO

P
Population
Vagotomized, paralyzed, decerebrate cats
I
Intervention
Simultaneous recordings from sympathetic nerves (cervical sympathetic, inferior cardiac, splanchnic) and medullary neurons analyzed via partial coherence analysis
O
Outcome
Correlation of medullary neuron activity to different sympathetic outflows (unit-nerve coherence at 2-6 Hz and 7-13 Hz)surrogate

Partial coherence analysis is a powerful tool for studying differential connectivity between medullary sympathetic-related neurons and sympathetic output populations.
