Abstract
The possibility of voluntary training of the independent component of event-related potentials (ERPs) by the method of biological feedback (BFB) using a modified two-stimulus test of Go/NoGo paradigm was studied. Ten subjects had to increase the amplitude of the P3b component of ERPs induced by the Go stimulus during one training session. This component is generated in the parietal cortex and is associated with an operation of action engagement. The study consisted of three sessions that included determination of the average amplitude, training, and placebo. It was found that the amplitude of the P3b component did not significantly change during the training and placebo sessions as compared to the session of threshold measurement, whereas the amplitude of the SPD component, which was also observed in ERPs in response to the Go stimulus, significantly decreased in both sessions. According to the sLORETA data, the source of the SPD component is located in the parahippocampal area. The results obtained help to determine further pathways to study the possibility of the use of BFB for correction of components of cognitive evoked potentials.
