The aim of this study was to develop a NIRS-based neurofeedback system to modulate activity in the prefrontal cortex (PFC). We evaluated the effectiveness of the system in terms of separability of changes in oxy-Hb and its derivative. Training with neurofeedback resulted in higher separability than training without neurofeedback or no training, suggesting that the neurofeedback system could enhance self-control of PFC activity. Interestingly, the dorsolateral PFC exhibited enhanced activity and high separability after neurofeedback training. These observations suggest that the neurofeedback system might be useful for training subjects to regulate emotions by self-control of dorsolateral PFC activity.
本研究旨在开发一种基于近红外光谱（NIRS）的神经反馈系统，以调节前额叶皮层（PFC）的活动。我们评估了该系统在区分氧合血红蛋白（oxy-Hb）及其衍生物变化方面的有效性。与无神经反馈或无训练相比，神经反馈训练可提高可分离性，这表明神经反馈系统可以增强 PFC 活动的自我控制。有趣的是，神经反馈训练后背外侧前额叶皮层（dorsolateral PFC）的活动增强且可分离性高。这些观察结果表明，该神经反馈系统可能有助于通过自我控制背外侧前额叶皮层活动来训练受试者调节情绪。
