[Motor conditioned reactions at different stages of normal human nocturnal sleep and their electrographic correlates].

Motor conditioned reaction was studied at different sleep phases in 13 subjects by EMG and mechanogram parameters compared to SGR and EEG. During paradoxical phase motor conditioned reaction appeared more often than in the slow-wave sleep, but in a reduced form. At various sleep stages the motor conditioned reaction regularly appeared at the background of the rise in the level of cortical functional state before conditioned stimulus. At all sleep stages completed motor reaction is fixed in the consciousness. However, amnesia of conditional stimulus perception and of motor reaction to it is rapidly developed, in particular in the slow-wave phase.

[Fast positive cortical potentials of the human cerebral hemispheres to visual stimuli evoking saccades].

The EEG was recorded in 7 healthy subjects aged 20-25 years according to the International 10-20 System in the frontal and parietal derivations (F3, F4, Pz, P3, P4) during the saccades related with the visual stimuli. A complex of fast (positive and negative) event-related potentials was recorded in response to visual stimulation before the saccade onset. The amplitude and spatial distribution of these potentials depended on the saccade latency, order of stimuli presentation, personality of a subject etc. The results suggest that the early positive potentials observed in the saccade latent period reflect the activation of the cortical structures which participate in programming and initiation of saccades.
