abstract：:Serotonin reveals ineffective (subthreshold) pathways from the C2 lateral funiculus to ipsilateral phrenic motoneurons in spinalized rats. The objective of the present study was to investigate serotonergic modulation of crossed-spinal pathways to contralateral phrenic motoneurons. Rats (n = 10) were anesthetized (uret...
