"Pure" motor hemiplegia.

Attenuation of cerebral evoked responses after stimulation of the median nerve in the hemiplegic limbs suggested that an apparently pure motor hemiplegia in some patients may not have pure involvement of the corticospinal system. Frontoparietal metastasis, infarction in basis pontis and medullary pyramid, and occlusion of internal carotid artery in the neck resulted in pure motor hemiplegia in some individuals.

"Alpha-like" rhythms in electroencephalograms in coma after cariac arrest.

Electroencephalograms (EEGs) of 12 comatose patients showed "alpha-like" rhythms after cardiac arrest. Four patients revealed a stage II sleep pattern and two patients showed signs of reactivity in their EEGs. One patient recovered with minimal impairment of memory, one patient lived for 3 months, and 10 died 3 ot 30 days after cardiac arrest. Examination of the brain demonstrated the usual anoxic lesions in three patients and "respirator brain" in one. In three patients with ventral pontine syndrome, a somewhat similar EEG pattern, but with distinct differences in topography and reactivity, was observed. In order to recognize alpha-like rhythms in comatose patients after cardiac arrest, EEGs should be recorded daily for several days.
