[Effects of two drugs substituted o-anisamides: sulpiride and sultopride on the sleep awakening cycle (author's transl)].

The study of the sleep awakening cycle was carried out on implanted cats free of their movements, which received separately each drug in long lasting intake, inorder to differentiate their behavioural and electrophysiological activities. The qualitative and quantitative changes induced by these o-anisamides are reported. Like in man, sulpiride was found to be quite an original substance.

[Benzodiazepines and limbic system. Anxiety and vigilance (author's transl)].

A neurophysiological study of 4 benzodiazepines in the free implanted cat serves as basis to a discussion concerning tranquilizers, anxiety and vigilance. The electrophysiological and behavioural effects of diazepam, nitrazepam, lorazepam and of clorazepate dipotassique are analysed and compared between them and other psychotropic drugs. Their mode of action on the behaviour, on the bioelectric cortical and hippocampal rhythms, is explained according to recent biochemical data.
