Implication

Extends mapping of carotid body reflex arcs in dogs; leaves open translation to human autonomic control.

Structured PICO

Population

Dogs under chloralose-urethane anaesthesia

Intervention

Separate unilateral stimulation of the chemoreceptors of the two carotid bodies

Outcome

Distribution of three primary reflex responses: parasympathetic bradycardia, sympathetic vasoconstriction, and increase in somatic phrenic nerve activitysurrogate

Unilateral carotid body stimulation in dogs elicits bilateral reflex vasoconstriction and phrenic nerve activity, but reflex bradycardia shows a contralateral predominance when one vagus nerve is blocked.
