From: The course of facial corticobulbar tract fibers in the dorsolateral medulla oblongata
Schematic representation of the course of the corticobulbar tract to the facial nucleus that descend to the level of the medulla oblongata. a Sagittal section. b Coronal section. c Cross-section at the level of the inferior olivary nucleus. The corticobulbar tract (dotted line) to the facial nucleus descends along with the corticospinal tract (CST) to the medulla. Then, after forming a loop and decussation, it ascends through the medial and ventral areas of the dorsolateral medulla to the facial nucleus in the caudal pons. AF, ascending fibers; CST, corticospinal tract; DF, descending fibers
