Figure 6. The phrenic motor nucleus receives synaptic inputs from spinal cord interneurons.

Figure 6.

These propriospinal neurons do not produce the fundamental respiratory rhythm of breathing but play a role in modulating the excitability of phrenic motoneurons and coordinating postural, locomotor and respiratory movements. These cells may also provide a neural substrate for promoting diaphragm motor recovery after spinal cord injury.
