Why the study?
The brain network supporting cardiorespiratory coupling remains poorly understood.
This preclinical study proposes a neural network model with linked recurrent inhibitory loops that explains how blood pressure and baroreceptor reflexes tune respiratory motor patterns.
Should not yet influence clinical cardiorespiratory care; leaves open translational validation of baroreceptor-respiratory networks.
The brain network that supports cardiorespiratory coupling remains poorly understood. Using multielectrode arrays, we tested the hypothesis that blood pressure and baroreceptor reflexes "tune" the breathing motor pattern via a raphe-pontomedullary network. Neuron responses to changes in arterial pressure and identified functional connectivity, together with altered high frequency and slow Lundberg B-wave oscillations, support a model with linked recurrent inhibitory loops that stabilize the respiratory network and provide a path for transmission of baroreceptor signals.
