Cells of origin of spinopontine fibers in the rat.
When wheat germ agglutinin-horseradish peroxidase conjugate was injected into the caudal part of the medial, lateral, ventral and peduncular pontine nuclei in the rat, retrogradely labeled spinal neurons were found contralaterally in the intermediate basilar nucleus (IBN) in the upper two cervical cord segments, and in laminae VI and VII in the lumbar cord segments. The IBN appeared to send fibers mainly to the caudomedial part of the pontine nuclei, while laminae VI and VII of the lumbar cord segments of the caudolateral part of the pontine nuclei.
