摘要:

工作记忆的神经振荡机制研究是当前记忆领域的研究热点之一。那么, 神经振荡仅仅是工作记忆过程的伴随现象, 还是直接参与并调控了工作记忆的加工过程?已有研究发现, 大脑内部的神经振荡活动在外界节律性刺激的驱动下, 逐步与外界刺激节律相位同步化, 这一现象被称为“神经振荡夹带”。重复经颅磁刺激(repetitive Transcranial Magnetic Stimulation, rTMS)和经颅交流电刺激(transcranial Alternating Current Stimulation, tACS)干预研究基于此现象, 对大脑局部脑区施加节律性磁、电刺激, 进而调控工作记忆过程中特定频段的神经振荡活动、跨频段的神经振荡耦合或跨脑区的神经振荡相位同步, 为神经振荡参与工作记忆加工提供较为直接的因果证据。未来研究需考虑从脑网络的角度出发, 调控多个脑区之间的神经振荡活动, 进一步考察神经振荡对工作记忆的影响。此外, 还需注意探索和优化rTMS/tACS调控工作记忆的刺激方案, 并辅以客观的脑电记录, 提高该类研究的有效性和可重复性, 最终达到提高工作记忆能力的目的。

Abstract:

The study of the neural oscillation mechanism of working memory (WM) is one of the current research hotspots in the field of memory. Previous studies have provided abundant evidence for the relationship between working memory process and brain oscillation by magnetoencephalography (MEG)/ electroencephalography (EEG). However, that naturally invites a question: it is yet not clear whether neural oscillations are only a concomitant phenomenon in the WM process, or if they are directly involved in and can help regulating the WM processing. Several studies have found that brain neural oscillatory activity could be driven by external rhythmic stimuli and gradually synchronizes with the phase of external rhythmic stimuli via a phenomenon known as "neural oscillatory entrainment". Based on this, a lot of Repetitive Transcranial Magnetic Stimulation (rTMS) and transcranial Alternating Current Stimulation (tACS) intervention studies conducted by modulating neural oscillatory activity provided more direct causal evidence of the relationship between neural oscillatory activity and working memory processing. We reviewed the rTMS/tACS studied on the field of human working memory which provided the casual evidence between the working memory processing (such as encoding, retention and retrieval) and neural oscillatory activity in specific frequency bands, phase-amplitude synchronization and phase synchronization between brain regions. Future studies may look into modulating multiple brain nodes underlying WM by a network approach via rTMS/tACS. Besides, to improve the effectiveness and repeatability of rTMS/tACS intervention, new research in the field should also clarify how to effectively apply rTMS/tACS intervention, supplemented with objective EEG recording to monitor the neural oscillation entrainment.

Key words: working memory, oscillation entrainment, rTMS, tACS
