A common pattern of reduction in both rapid eye movement and non-rapid eye
movement sleep associated with various lateral gaze paralyses was present
in four cases of brain-stem stroke. From computed tomographic scan data,
clinical inferences, and, in two cases, neuropathologic sections, the
common lesions were localized in the medial pontine tegmentum, ie, the
inner part of the gigantocellular and pontis centralis caudalis nuclei.
These data in humans were compared with lesions obtained experimentally in
cats.
