This paper contains a clinical, classical electroencephalographic and computerized electroencephalographic (by original methods) study of 271 cases with vertebro-basilar strokes, all the cases being verified by transcranial Doppler ultrasound investigations and some of the patients by morphopathological studies. In the first part, the standard EEG modifications in relation with the clinical pictures and with the affected arterial field are presented. In the second part, the aspects of the computerized EEG recordings with the carrying out of the cortical EEG mappings which have brought important contributions in setting down the topography of the infarctions are discussed.

Other neuropsychiatric affections and factors which could generate the symptomatology of restless legs syndrome were not included. The EEG recordings demonstrated evident reticular neuronal hypersynchrony generated by hyperpnoea (sinusoidal slow waves).

Polysomnographic recordings were carried out for a continuous period of eight hours. All this time, the patients have been observed by video-monitorization on a closed infrared circuit screen.

Clinical and polysomnographical investigations have been performed in 35 patients with REM narcolepsy (group 1), comparatively with 45 patients suffering from symptomatic hypersomnia in NREM sleep (group 2). The polysomnographical recordings have been made by: a) continuous recording covering 24 h; b) submission of the subjects to the "Maintenance of wakefulness tests" (MWT). In 20 narcoleptics and in 12 normal subjects, computerized EEG mappings were performed in wakefulness and in different sleep stages.

One hundred and twelve patients with temporal lobe epilepsy were studied. Continuous polysomnographical recordings were performed for eight hours, the patients being video-monitored all the time. These researches, completed with computerized EEG cortical mappings demonstrated a peculiar activation of the temporal foci during REM phases and during some stages of LSWS.
