Pontomedullary vs pontomesencephalic transmission time. A diagnostic aid in multiple sclerosis

Caudal vs rostral transmission time has been studied in patients with multiple sclerosis (MS). In the majority of the cases, prolongation in latency was more severe in the caudal segment, which suggests that this part of the brainstem is more commonly affected in MS. The difference between pontomedullary and pontomesencephalic transmission time yields a variable that may prove a valuable adjunct in the electrodiagnosis of MS.
