Background Left frontal alpha oscillations are associated with decreased approach motivation and have been proposed as a target for non-invasive brain stimulation for the treatment of depression and anhedonia. Indeed, transcranial alternating current stimulation (tACS) at the alpha frequency reduced left frontal alpha power and was associated with a higher response rate than placebo stimulation in patients with major depressive disorder (MDD) in a recent double-blind placebo controlled clinical trial.

在一项随机临床试验中，通过经颅交流电刺激减少重度抑郁症患者的左额叶 α 振荡与情境有关

背景左额叶阿尔法振荡与减少的接近动机有关，并已被提议作为非侵入性脑刺激治疗抑郁症和快感缺乏症的目标。事实上，在最近的一项双盲安慰剂对照临床试验中，α 频率的经颅交流电刺激 (tACS) 降低了左额叶 α 功率，并且与重度抑郁症 (MDD) 患者相比安慰剂刺激的反应率更高。
