The study verifies the hypothesis that the neuron code consists of two patterns of non-fading waves of neuron activity. It is also argued that an elementary image corresponds with one single pattern of waves - the interconnected cyclic activity of the cells of one neuron group. The paper gives formulae connecting the parameters of the neuron code, such as, on the one hand, memory volume and speed, subjective estimation of stimuli intensity and the probability of choosing various actions, and, on the other hand, the neurophysiological parameters and characteristics of the information to be processed. The author suggests a method of constructing a psychological profile of a person by drawing on the background encephalogram. The profile includes such features as the abilities to learn, communicate, perform and lead other people, in accordance with the main scales of the MMPI.
