时间干扰经颅交流电刺激(TI-tACS)是一种无创脑刺激新技术。先前的研究已经表明 TI-tACS 在选择性刺激大脑区域方面的有效性。然而,其调节人脑神经元的安全性尚未经过测试。在这项研究中,招募了 38 名健康成年人,在主动(2 mA,20/70 Hz,30 分钟)或假(0 mA,0 Hz,30 分钟)TI-tACS 前后进行一系列有关安全性问题的神经学和神经心理学测量。神经学和神经心理学测量包括脑电图(EEG)、血清神经元特异性烯醇化酶(NSE)、蒙特利尔认知评估(MoCA)、普渡钉板测试(PPT)、加州计算机评估包(A-CalCAP)的缩写版本、视觉模拟情绪量表(VAMS-R)的修订版、自我评估量表 (SAS),以及有关不良反应(AE)的调查问卷。我们发现活动组和假组 TI-tACS 组的测量结果没有显着差异。同时,在 19 名参与者的主动刺激组中,没有报告或观察到严重或无法忍受的不良反应。这些结果表明,在典型经颅电刺激 (TES) 条件(2 mA、20/70 Hz、30 分钟)下的人脑刺激研究中,TI-tACS 在神经和神经心理学功能以及不良反应方面是安全且可耐受的。
Temporal interference transcranial alternating current stimulation (TI-tACS) is a new technique of noninvasive brain stimulation. Previous studies have shown the effectiveness of TI-tACS in stimulating brain areas in a selective manner. However, its safety in modulating human brain neurons is still untested. In this study, 38 healthy adults were recruited to undergo a series of neurological and neuropsychological measurements regarding safety concerns before and after active (2 mA, 20/70 Hz, 30 min) or sham (0 mA, 0 Hz, 30 min) TI-tACS. The neurological and neuropsychological measurements included electroencephalography (EEG), serum neuron-specific enolase (NSE), the Montreal Cognitive Assessment (MoCA), the Purdue Pegboard Test (PPT), an abbreviated version of the California Computerized Assessment Package (A-CalCAP), a revised version of the Visual Analog Mood Scale (VAMS-R), a self-assessment scale (SAS), and a questionnaire about adverse effects (AEs). We found no significant difference between the measurements of the active and sham TI-tACS groups. Meanwhile, no serious or intolerable adverse effects were reported or observed in the active stimulation group of 19 participants. These results support that TI-tACS is safe and tolerable in terms of neurological and neuropsychological functions and adverse effects for use in human brain stimulation studies under typical transcranial electric stimulation (TES) conditions (2 mA, 20/70 Hz, 30 min).
