Weaning Off Mental Tasks to Achieve Voluntary Self-Regulatory Control of a Near-Infrared Spectroscopy Brain-Computer Interface

摘要: As a noninvasive and safe optical measure of hemodynamic brain activity, near-infrared spectroscopy (NIRS) has emerged as potential brain-computer interface (BCI) access modality. Currently, to the best our knowledge, all NIRS BCIs use mental tasks elicit changes in regional activity. One limitations using is that they can be cognitively demanding, unintuitive. The goal this work was explore development neurofeedback-based BCI weans users off tasks, instead voluntary self-regulation. Ten able-bodied participants were recruited for study. After ten sessions two personalized increase decrease participant’s asked, remaining sessions, stop performing their only desire modulate By final online session, able exclusively self-regulation with an average accuracy $79 \pm 13\hbox{\%}$ . Additionally, majority indicated control via less taxing more intuitive than operation tasks.
