[Evoked electrical activity. The methodological problems and outlook].

Basic methodological problems of recording the evoked electrical activity (EEA) are analysed in terms of its genesis. Further progress with non-invasive methods seems to be limited. The proposed technique provides an a priori "space-time" information due to measurement of several classes of the EEA and simultaneous stimulation of two subsystems of the CNS.

[The evaluation of the effect of variable latency periods on the averaged evoked potential].

The data on averaged EPs were used for simulation of stationary responses to sensory stimuli. The EP variability was observed when the range of the latency shift exceeded 90 msec. The N1, P2 and N2 components of the averaged long-latency auditory EPs were chosen for estimation of the latent variation range in normal subjects using encephaloscopy (RES) technique.

[Comparative study of the laws governing cutaneous blood flow in the thermoneutral zone].

A simplified model of the rabbit thermoregulatory system in the thermoneutral zone revealed three principles of the skin blood flow control. The temperature fluctuations in the thermoneutral zone could only be obtained in case of the on-off response of the control.
