[Application of the function of the number of states of dynamic system to investigation of electroencephalographic reaction to photostimulation].
A new way of EEG analysis is developed, which makes it possible to reveal a reaction of the brain cortex to external stimulation at a low response level. The method is based on the creation of an image of the EEG curve in the discrete phase space and comparison of a current condition with the conditions from a certain basic set. The strength of reaction to external stimulation is defined by the incidence of conditions novel with respect to the basic ones.
