Abstract
Sensorimotor rhythm (SMR) neurofeedback training (NFT) has an important role in improvement of cognitive functions in both clinical and healthy individuals. It is very possible that in SMR NFT adjacent frequency bands, such as alpha and beta1, be affected by SMR enhancing neurofeedback. Therefore, the adjacent frequency bands, in addition to SMR, may be associated with the improvement of the cognitive functions. Eight sessions of NFT were applied to healthy individuals to enhance their SMR activity. In order to investigate the effect of SMR enhancing neurofeedback on the power of adjacent frequency bands, correlation between the change in SMR activity and the change in alpha or beta1 activity was computed. The results revealed that there is a highly significant positive correlation between the change in SMR and beta1 activities. The given outcome suggests that during SMR NFT, the effect of both SMR and beta1 be considered together on the improvement of the cognitive functions.
