Easier learning after neurofeedback of alpha waves
Scientists at the Ruhr-Universität Bochum were able to prove that the alpha oscillations of the brain play an essential role in learning and that they can be trained by neurofeedback. Alpha waves range from 8 to 13 Hertz and are believed to suppress irrelevant information. A high proportion of alpha waves is associated with high attention and better results in cognitive tasks.
In the study 76 persons trained their alpha activity with the neurofeedback system THERA PRAX®. Half of the participants were supposed to promote alpha waves, the other half to suppress them. After only two training sessions, both groups succeeded in changing the activity in the desired direction.
In the subsequent learning task for the sense of touch, the group with increased alpha activity performed significantly better than an untrained control group. In the other group there was no learning effect.
The scientists Marion Brickwedde and PD Dr. Hubert Dinse hope from the results that alpha neurofeedback will be beneficial for everyday learning as well as in rehabilitation and other clinical areas.
