研究目的:

1.通过临床研究验证经皮耳迷走神经刺激(taVNS)治疗失眠的疗效。 2.通过迷走神经受刺激后心率变异性兴奋的大小、临床结果与fMRI的变化验证患者迷走神经的敏感性与活性的不同是影响taVNS治疗失眠疗效的关键。

Objectives of Study:

1. To validate the efficacy of transcutaneous auricular vagus nerve stimulation (taVNS) in the treatment of insomnia; 2. To validate the sensitivity and activity of vagus nerve in insomnia patients is the key to the efficacy of taVNS treatment through the heart rate variability, clinical score and fMRI after vagus nerve stimulation.
