Improving Efficiency of the Ideomotor Brain Computer Interface (BCI) in the Neurofeedback Paradigm
2018
In the present scientific research, we suggested that neurofeedback trainings in the direction of increasing the power of the sensorimotor rhythm (SMR) at the rest station will lead to an increase in the amplitude of the desynchronization signal, while performing or imagining the movement, which in turn will lead to an increase in the decoding accuracy in the ideomotor brain-computer interfaces (BCI). As a result it was found that training the SMR in the neurofeedback paradigm does indeed have a positive effect on the accuracy of the command classification (classificatory accuracy) in the ideomotor BCI. A positive result was observed in the experimental group, a negative result in the control group (subjects who received a feedback signal not associated with the current activity of the SMR). Moreover, for the first time we discovered an unexpected effect of the spatial reorganization of the SMR generator (by topography analysis) as a result of the trainings in the neurofeedback paradigm.

Student Theses at HSE must be completed in accordance with the University Rules and regulations specified by each educational programme.

Summaries of all theses must be published and made freely available on the HSE website.

The full text of a thesis can be published in open access on the HSE website only if the authoring student (copyright holder) agrees, or, if the thesis was written by a team of students, if all the co-authors (copyright holders) agree. After a thesis is published on the HSE website, it obtains the status of an online publication.

Student theses are objects of copyright and their use is subject to limitations in accordance with the Russian Federation’s law on intellectual property.

In the event that a thesis is quoted or otherwise used, reference to the author’s name and the source of quotation is required.
