[Alterations of arousal in some psychopathologic states]

An electro-behaviour dissociation was described, at first by animals next about the man, in experiment testing and in the drug addictions. This non concordance appear as lesser if it is be considered not only the sleeping waves but also all the electrical signs of the vigil state: non-existent, fluctuating, limited in topography, behind the stimulation, incomplete or emphasized. In this view we study some pathological states: narcotic and alcoholic addictions, confusion and pre-senile illness. Sometimes it is the abnormal sleep (coma or amazement) which alter the vigil state: absent, decreased, etc. Sometimes the vigilance is "numbed", the behaviour and the recording are those of lethargy. Sometimes also, the drowsiness has insomnia characteristics, associating a deep sleep loss, a reactivity to stimulations at once emphasized and undiscriminated, and "strangeness" insurmontable for the consciousness (perplexity, delusions, nightmare and level anomalies).
