摘要：

The location of bulbospinal neurons with axon collaterals in both phrenic nuclei were determined by injecting two different fluorescent tracers into the right and left C4 cervical spinal cord. In contrast to single-labeled neurons that were found throughout the rostrocaudal extent of the medulla, the majority of double-labeled neurons were located in the rostral ventral respiratory group. Only a few double-labeled neurons were found in the ventrolateral nucleus of the solitary tract. The role of this bilateral pathway in synchronizing the activity of the phrenic nucleus is discussed.
