[Somatosensory evoked potentials in the sleep-wakefulness cycle in healthy subjects and narcolepsy patients].
Studies of somatosensory evoked potentials (SSEPs) were conducted in various functional states of sleep-alertness cycle (relaxed alertness, 2-nd and delta-stages of slow sleep, rapid sleep) in 7 healthy subjects and 8 patients with polysymptom narcolepsy. Integrated amplitude (IA) was calculated in poststimulus intervals, accordingly to SSEPs division into groups of early (20-80 ms), mean (80-200 ms) and late (200-400 ms) components. It has been shown that in patients with polysymptom narcolepsy IA of all SSEPs components in alertness was lower than in healthy subjects; during sleep higher IA values of earlier components were found in comparison with healthy subjects and lower values--of later negative wave at slow sleep. Psychophysiological interpretation of high amplitude negative shift in the area of late SSEPs components during slow sleep is suggested.

[A theoretical analysis of systematic "parents X progeny" inbreeding in animals in the absence of selection].
Theoretical analysis of the structure of a model population of D. melanogaster under systematic inbreeding--"parents x progeny"--has been conducted using a computer and the original method elaborated. Theoretical relationships between the development of homozygous isolated groups of progeny of 30 generations and their backcrosses with heterozygous and homozygous common ancestors A male and B female were established.
