Abstract

Abstract : Aim: Neurofeedback has been studied with the aim of controlling cerebral activity. Near‐infrared spectroscopy is a non‐invasive neuroimaging technique used for measuring hemoglobin concentration changes in cortical surface areas with high temporal resolution. Thus, near‐infrared spectroscopy may be useful for neurofeedback, which requires real‐time feedback of repeated brain activation measurements. However, no study has specifically targeted neurofeedback, using near‐infrared spectroscopy, in the frontal pole cortex. Methods: We developed an original near‐infrared spectroscopy neurofeedback system targeting the frontal pole cortex. Over a single day of testing, each healthy participant ( n = 24) received either correct or incorrect (Sham) feedback from near‐infrared spectroscopy signals, based on a crossover design. Results: Under correct feedback conditions, significant activation was observed in the frontal pole cortex ( P = 0.000073). Additionally, self‐evaluation of control and metacognitive beliefs were associated with near‐infrared spectroscopy signals ( P = 0.006). Conclusion: The neurofeedback system developed in this study might be useful for developing control of frontal pole cortex activation.
