本文总结了经颅交流电刺激（Transcranial Alternating Current Stimulation, tACS）的原理、波形，重点介绍了不同刺激方案，以及相关的新颖研究，包括tACS和脑电结合的研究、个体alpha频率刺激研究/视觉刺激研究、小脑刺激研究等，表明tACS是研究认知神经相关性的重要工具 ...

Transcranial alternating current stimulation (tACS) is a unique form of non-invasive brain stimulation. Sinusoidal alternating electric currents are delivered to the scalp to affect mostly cortical neurons. tACS is supposed to modulate brain ...

2021年2月16日 · Transcranial alternating current stimulation (tACS) is a relatively new technique that can effectively modulate oscillatory brain activity through weak...

2022年11月12日 · Here we applied intermittent theta-burst stimulation (iTBS), an established TMS protocol known to induce LTP-like cortical plasticity, simultaneously with transcranial alternating current...

2021年12月15日 · We developed a custom circuit to synchronize pulses of transcranial magnetic stimulation (TMS) at precise phases within the waveform of transcranial alternating current stimulation (tACS), with the objective to deliver bilateral and simultaneous in-phase stimulation across each of the two hemispheres.

经颅磁刺激 (transcranial magnetic stimulation,TMS)和经颅直流电刺激（transcranial direct current stimulatioin, tDCS）作为无创脑刺激最常用的两种技术，在治疗神经系统疾病中展示出了非常有潜力的应用价值。 与手术及深部脑刺激相比，无创脑刺激具有无痛、无创、操作简便、安全可靠等优点。 今天我们就来看看这两种技术有何共同点和差异，并根据这些差异在购买设备时做出合理的选择。 TMS的基本原理. TMS 的基本原理在于磁刺激器线圈可以产生随时间变化的磁场，从局 …

Through neuromodulation of phasic, neural activity, tACS is a powerful tool to investigate the neural correlates of cognition. The rapid development in this area requires clarity about best practices. Here we briefly introduce tACS and review the most compelling findings in the literature to provide a starting point for using tACS.

2025年2月3日 · We found that tACS administered during functional magnetic resonance imaging yielded a frequency-, mental state- and topologically-specific effect of theta stimulation (but not other frequencies)...

近年来，经颅交流电刺激（transcranial alternating current stimulation, tACS）在研究非侵入性人脑活动振荡的因果作用方面发挥了核心作用。与tDCS和tRNS相比，tACS的影响可以直接与大脑振荡活动相关联。传统上，主要的作用机制归因于夹带和共振。

Transcranial alternating current stimulation (tACS) seems likely to open a new era of the field of noninvasive electrical stimulation of the human brain by directly interfering with cortical rhythms. It is expected to synchronize (by one single ...
