在单独定义的δ，θ，α-1，α-2和α-3波段的EEG谱功率和相干性估计用于识别和表征涉及冥想状态的大脑区域，其中集中的内化注意力引起情感上积极的“幸福”体验。幸福状态伴随着前额叶和中线θ同步增加以及前额叶和后联合皮层之间的θ远距离连接增强，左前额叶区域（AF 3部位）具有明显的“重心”。情绪体验的主观分数与θ显著相关，而内化注意力的分数与θ和α的同步性较低。我们的研究结果表明，θ和α振荡网络活动与内化注意力和积极情绪体验的状态有选择性关联。(C)2001爱思唯尔科学爱尔兰有限公司保留所有权利。
EEG spectral power and coherence estimates in the individually defined delta, theta, alpha-1, alpha-2, and alpha-3 bands were used to identify and characterize brain regions involved in meditative states, in which focused internalized attention gives rise to emotionally positive 'blissful' experience. Blissful state was accompanied by increased anterior frontal and midline theta synchronization as well as enhanced theta long-distant connectivity between prefrontal and posterior association cortex with distinct 'center of gravity' in the left prefrontal region (AF3 site). Subjective scores of emotional experience significantly correlated with theta, whereas scores of internalized attention with both theta and alpha lower synchronization. Our results propose selective associations of theta and alpha oscillating networks activity with states of internalized attention and positive emotional experience.
