Transcranial alternating current stimulation (tACS) was introduced about a decade ago as a non-invasive brain stimulation method to modulate neural oscillations in a relatively safe manner in humans. However, the possibility to induce genuine neural entrainment with low current intensities has been questioned. In a recent study, Johnson and colleagues provide direct evidence for the efficacy of low-intensity tACS to induce neural entrainment in awake monkeys. These findings have important translational implications for human non-invasive neuromodulation research.

低强度 tACS 能否真正在体内诱导神经活动？

大约十年前，经颅交流电刺激 (tACS) 作为一种非侵入性脑刺激方法被引入，以相对安全的方式调节人类的神经振荡。然而，人们质疑用低电流强度诱导真正的神经夹带的可能性。在最近的一项研究中，Johnson 及其同事为低强度 tACS 诱导清醒猴子神经夹带的功效提供了直接证据。这些发现对人类非侵入性神经调节研究具有重要的转化意义。
