| Outline of Final Research Achievements |
We directed our attention towards investigating the responsivity of neurofeedback (NF) therapy for ADHD, thereby advancing our research on cerebral functionality. First, brain activity was quantified through fNIRS employing a Stroop task. The subcentral area and the retrosubicular area exhibited no activation. We employed them as reference channels (REF). Second, subjects underwent NF guided by the contrast between REF and the inferior frontal gyrus and dorsolateral prefrontal cortex, both being target regions for ADHD treatment. Measurements of the changes in brain activity in each region in response to frontal lobe tasks between pre- and post-NF were conducted. We are continuing to analyze these data, and based on the observed functional changes in brain regions, we aim to establish a more effective NF method as a treatment. In addition, such a method could be applied to other treatments, such as objective diagnosis, treatment evaluation, and magnetic stimulation, as a biomarker.
