Retrieval of positive Autobiographical Memory (AM) has been reported to increase positive emotions in healthy population. Evidence suggests that positive AM retrieval tasks are correlated with synchronisation of frontal Theta rhythms (4-8Hz). The present study has developed the Electroencephalography (EEG) based Neurofeedback (NF) protocols to promote voluntary elevation or up-regulation of positive AM retrieval related Theta rhythms over F3, Fz, F4 electrode sites (10-20 System). The protocols were evaluated with a human participant in 10-day NF training. It observed that the average amplitude of observed Theta rhythms in each NF regulation block gradually increased over days of training and most was prominent at Fz electrode site. Furthermore, a larger peak at 6Hz was present in the spectrum of the observed Theta with later trial day suggesting up-regulation of Frontal Midline Theta (FmT) rhythms.
据报道，在健康人群中，提取积极的自传体记忆（AM）会增加积极情绪。有证据表明，积极的AM提取任务与额叶θ节律（4-8Hz）的同步相关。本研究开发了基于脑电图（EEG）的神经反馈（NF）方案，以促进在F3、Fz、F4电极位点（10-20系统）上与积极AM提取相关的θ节律的自愿提升或上调。该方案在一名人类参与者身上进行了为期10天的NF训练评估。结果观察到，在每个NF调节块中，观察到的θ节律的平均振幅在训练过程中逐渐增加，且在Fz电极位点最为显著。此外，在观察到的θ节律的频谱中，后期试验日出现了一个更大的6Hz峰值，表明额叶中线θ（FmT）节律上调。
