The definition of waking stages on the basis of continuous polygraphic recordings in normal subjects.
Polygraphic examinations were made during the day on 6 normal subjects. Simultaneous evaluation of EEG, EOG and EMG was carried out over 30 sec epochs. The data thus obtained were correlated with the various types of behaviour and activities during the day and then interpreted. Six conditions could be defined corresponding to different waking stages. The analysis of the material obtained shows that the existence of these waking stages is of interindividual validity.
