Abstract

Previous study has shown that cognitive training with neurofeedback (CT-NF) using the down-regulation improved cognitive functions in young adults. Neurofeedback has two strategies to manipulate brain activities (down-regulation and up-regulation). However, it is still unknown a benefit of the CT-NF with the up-regulation on cognitive functions. In this study, we investigated whether the CT-NF with the upregulation improves a wide range of cognitive functions compared to the cognitive training (CT) alone. In this double-blinded randomized control trial (RCT), 60 young adults were randomly assigned to one of the three groups: CT-NF group, CT alone group, and an active control (ACT) group who played a puzzle game. Participants in three groups used the same device (tablet PC and 2ch NIRS (near-infrared spectroscopy)) and performed the training game for 20 min every day for four weeks. We measured brain activities during training in all groups, but only the CT-NF received NF. We measured a wide range of cognitive e functions before and after the intervention period. The CT-NF groups showed superior beneficial effects on episodic memory, working memory, and attention compared to the CT alone and the ACT groups. In addition, the CT-NF groups showed the increase in brain activities during CT was associated with improvements in cognitive functions. This study firstly demonstrated that the CT-NF using the up-regulation strategy has beneficial effects on cognitive functions compared to the CT alone. Our results suggest that greater brain activities during CT would enhance a benefit from CT.
