The present report is concerned with a systematic description and evaluation of the temporal order of return of the cognitive processes which "drop out" during the stuporous interval following convulsive seizures induced by metrazol in a group of schizophrenic patients. The functions which comprise the cognitive aspects of consciousness reappeared in the patients in an order which was so consistent that after some exploratory investigation it was possible to predict their occurrence accurately. Although the present data on the nature of disturbance of these functions and the order of their "normalization" may be specific for the postconvulsive period which characterizes metrazol-induced seizures, it is also possible that they may be more generally applicable to states of "clouded consciousness," "stuporousness" and "confusion" which characterize other postconvulsive clinical states. These clouded intervals are in need of more careful evaluation; except for the clinical descriptions of these states in terms of such concepts
