Main time characteristics of sleep were studied in 9 adult dogs in experiments with 24-hr polygraphic recordings. The all-day sleep quantity (35%), circadian distribution of sleep with the maximum between 24 and 9 hours, more rapid rise of delta-sleep (DS) in the second half of day and of REM sleep in the first hours of night -- all these data suggest that(More)
In studying of dogs behaviour in coordinates system "Requirements and probability of their satisfaction" it has been established that selection of behaviour strategy is closely connected with individual typological properties of animals. In experiments with equally-probable alimentary reinforcement a direct correlation was found between the strength(More)
The analysis of negative emotiogenic influence in dogs carried out according to dynamics of levels of acetylcholine and catecholamine content in peripheral blood and concomitant changes of the higher nervous activity, allows to conclude about the participation of both cholinergic and catecholaminergic neurotransmitter systems in reactions to this influence(More)
Clinical studies revealed a significant increase in the peripheral blood levels of noradrenaline in patients with different forms of neurosis and neurosis-like states as compared to control subjects as well as heterogeneous or unidirectional but differently pronounced changes in blood levels of acetylcholine and adrenaline. Comparison of the clinical(More)
After single and repeated negative emotiogenic (neuroticizing) influences in phlegmatics and cholerics in a situation with different probability and value of reinforcement a change of behaviour strategy takes place--from the preference of a reinforcement of higher probability but worse quality to that of low probability but valuable. Strategy of behaviour(More)
Under the influence of diazepam in doses of 0.2-2.0 mg/kg in a situation of different probability and value of a reinforcement the dogs--sanguinics and melancholics change their strategy of behavior, from the preference at norm of a reinforcement of the low probability but the better quality to that of the high probability but the worse quality. Under the(More)
