Data concerning central (mu) rhythms in children are reported, these rhythms being studied by means of prolonged telemetric recording which makes it possible to study various experimental situations. Several different patterns of mu rhythm were observed in every subject, depending on the experimental situation. The level and the quality of attention on the(More)
This study concerns a case of infliltrating tumour of the pons in which a night sleep recording was performed. Selective disorganization of REM sleep was observed, with lack of muscular atonia and disturbances of tonic-phasic relationships. These data are discussed with respect to the results of local destructions performed experimentally in animals.
Seventy patients presenting symptoms of hysteria (49 women and 21 men) were selected among patients observed at the Institute Minkowska during the year. This work is part of a research work on socio-cultural and environmental factors which can change mental status of immigrants. These are all portugese workers presenting for the first time atypical mental(More)
Based on telemetric recordings performed on 6 children, a study of the time distribution of intra-clinical paroxysmal discharges was carried out. It was tested whether this distribution is stochastic, and if not so, whether is depends upon an internal biological rhythm or upon environmental and behavioural factors. The times of occurrence of paroxysmal(More)
A study of the paroxysmal activities in the course of all night sleep was carried out on 6 children aged 6 to 12 years, who were previously recored by means of biotelemtry during the day (cf. Findji et al. 1978). The discharges were analysed and quantified in the same way as in daytime but here in relation to the organization of sleep. The latter shows(More)
Three biotelemetric examinations and a whole night sleep recording were carried out in a 8 year old child whose behavior alternated between exicitation and autism. The E.E.G. showed 5 Hz. temporo-parietal sharp wave discharges lasting from 1 second to 20 minutes. These discharges were at times unilateral and predominantly right sided, at other times being(More)
