双生物反馈影响功能性半球不对称性和活动吗？一项试点研究
Does Double Biofeedback Affect Functional Hemispheric Asymmetry and Activity? A Pilot Study
摘要：
在目前的初步研究中，我们试图找出如何双神经反馈影响功能半球的不对称性和活动。我们检查了30名健康参与者（8名男性; 22名女性，平均年龄= 29岁; SD = 8）。为了测量功能性半球的不对称性和活动，我们在“双源”超前-滞后两分范式中使用计算机测侧法。双生物反馈包括8分钟的EEG振荡记录和5分钟的基本模式。在基本模式期间，EEG振荡器的电流幅度被转换成反馈声音，而α EEG振荡器的电流幅度被用于调制光信号的强度。双神经反馈并没有直接影响不对称本身，但加速个人的声音感知特性在前效应范式的双耳分听。需要进一步的研究来调查双重神经反馈训练对功能性大脑活动和不对称性的影响，考虑参与者的年龄，性别和动机。
英文摘要：
In the current pilot study, we attempt to find out how double neurofeedback influences functional hemispheric asymmetry and activity. We examined 30 healthy participants (8 males; 22 females, mean age = 29; SD = 8). To measure functional hemispheric asymmetry and activity, we used computer laterometry in the "two-source" lead-lag dichotic paradigm. Double biofeedback included 8 min of EEG oscillation recording with five minutes of basic mode. During the basic mode, the current amplitude of the EEG oscillator gets transformed into feedback sounds while the current amplitude of alpha EEG oscillator is used to modulate the intensity of light signals. Double neurofeedback did not directly influence the asymmetry itself but accelerated individual sound perception characteristics during dichotic listening in the preceding effect paradigm. Further research is needed to investigate the effect of double neurofeedback training on functional brain activity and asymmetry, taking into account participants' age, gender, and motivation.
