In a patient with an infiltrating intrapontine tumor the first component of the blink reflex on the lesion side was abolished, while all other components during ipsi- and contralateral stimulation were intact (fig. 1). Such a response pattern suggests a lesion, which selectively interupts the intrapontine afferent are of the mono- or disynaptic pathway underlying the early response (fig. 2).
