The respiratory role of the parabrachial nuclear complex (PNC) was investigated in alpha-chloralose-urethane anesthetized, vagotomized, paralysed and artificially ventilated rabbits by means of unilateral microinjections (10-20 nl) of 20 mM dl-homocysteic acid. Chemical stimulation elicited three main types of site-specific respiratory effects: excitatory, apneustic and inhibitory responses. The results suggest that the PNC plays a complex role in the control of breathing.

Abstract
The respiratory role of the parabrachial nuclear complex (PNC) was investigated in alpha-chloralose-urethane anesthetized, vagotomized, paralysed and artificially ventilated rabbits by means of unilateral microinjections (10-20 nl) of 20 mM dl-homocysteic acid. Chemical stimulation elicited three main types of site-specific respiratory effects: excitatory, apneustic and inhibitory responses. The results suggest that the PNC plays a complex role in the control of breathing.
