Abstract
  • Scientific evidence supporting the reliability of neurofeedback (NF) in modifying the electroencephalographic (EEG) pattern is still limited. Several studies in NF research and clinical setting have been focused to increase sensory-motor rhythm (SMR) and simultaneously decrease theta activity with the aim of increasing attention performance and reducing hyperactive and impulsive behaviors. The goal of the present study was to assess the efficacy of NF training to enhance the SMR/theta ratio across sixteen sessions of training in eight healthy volunteers. Results suggested an increase of SMR/theta across weeks of training. Theta activity was strongly and steadily inhibited since the first session of training with slight decreases in the following weeks; instead, SMR was strongly inhibited at the beginning and progressively increased across sessions. These results suggest that individuals are able to inhibit theta activity easily while they fail to increase SMR in the first sessions. On the other hand, a separate analysis performed on the baseline preceding NF revealed a decreasing trend of SMR/theta ratio across the 8 weeks of training. Results point to the importance of providing EEG data in addition to behavioral modification, during NF training, to avoid possible misinterpretation of results. (literal)
