Abstract

This study aimed to compare the effect of two neurofeedback protocols on learning a pursuit tracking task. Forty-two volunteers placed in three groups of alpha-suppression, theta-enhancement and control. In the alpha-suppression group, alpha amplitude suppressed at C4 before the training, while the participants in the theta-enhancement intended to increase theta amplitude at Pz and immediately after training. After training session, the subjects participated in retention tests within 90 minutes, 24 hours, and one week intervals. The results showed that the alpha-suppression group performed better than control group in the first retention test. Nevertheless, this superiority was not significant in subsequent retention tests, where no difference was observed between the groups. These findings revealed that the inhibition of alpha range in the motor cortex and subsequent higher excitability can likely leave beneficial effects on learning a motor skill, even though the sustainability of this effect over time needs to more studies.
