Assessing the Efficiency of the Ability to Intentionally Variate the Power of β2 Frequencies in the Frontal Lobes of the Cerebral Cortex

详细

We performed longitudinal examinations by neurofeedback in 17 subjects. The subjects were trained for 12 training seßsions (three weeks) to voluntarily increase the intensity of the ß₂ frequencies in the frontal EEG electrodes of the right (the D scenario) and the left (the S scenario) hemispheres. All the subjects were divided into three groups depending on the training efficacy: a group of subjects that successfully controlled the ß activity in the frontal electrodes of both hemispheres (nine subjects), a group of subjects that successfully controlled this activity only in the right hemisphere (four subjects), and a group of subjects that failed to train during the specified period (four subjects). Analysis of the obtained data showed that the training efficacy depended on the cognitive activity that was focused on achieving the corresponding EEG effects and on the individual personality characteristics.
