Polygraphic signals analysis system in neurophysiological experiment

A polygraphic signals analysis system used for neurophysiological experiments is designed for postanalysis of the data acquired during the exploratory experiment. The polygraphic signals are represented by signals of ECG, EMG, SCR, SPL, and breathing. These signals are acquired from the patient for a state estimation of a vegetative nervous system during the experiment. The polygraphic signals are acquired simultaneously with encephalographic signals. The simultaneous and synchronized acquisition from the patient of the set of all the mentioned above signals is a necessary condition for learning correlation between processes happening in the cortex of a brain, and processes occurring in a vegetative nervous system. A system destined for an exploratory experiment requires continuous modifying of operation and data processing algorithms pursuant to changes of experiment conditions at minimum costs
