Auricular vagus nerve stimulation (VNS) is a non-invasive treatment modality. Opinions that it can be used in the treatment of various clinical problems have gained importance in recent years. In this study, it was aimed to lay the groundwork for the use of the auricular VNS in different ears. Healthy individuals ( = 90) were divided into three groups: unilateral left ( = 30), unilateral right ( = 30), and bilateral ( = 30) auricular VNS. Electroencephalography (EEG) and electromyography (EMG) measurements were performed before and after auricular VNS (10 Hz, 300 µs, 20 min) for a single session. An increase in wrist extensor muscles activation was detected on the contralateral side of the auricular VNS application side. It has been observed that there is a general decrease in the power of high-frequency waves and an increase in the power of lower-medium frequency waves in various parts of the brain. Our findings suggest that the projection of the auricular VNS in the central nervous system may also affect the corticospinal tracts.
耳迷走神经刺激（VNS）是一种非侵入性治疗方式。近年来，关于其可用于治疗各种临床问题的观点变得越发重要。在本研究中，旨在为在不同耳朵使用耳迷走神经刺激奠定基础。将90名健康个体分为三组：左耳单侧刺激组（n = 30）、右耳单侧刺激组（n = 30）和双耳刺激组（n = 30）。在单次耳迷走神经刺激（10Hz，300µs，20分钟）前后进行脑电图（EEG）和肌电图（EMG）测量。在耳迷走神经刺激应用侧的对侧检测到腕伸肌激活增加。据观察，大脑各部位高频波功率普遍下降，中低频波功率增加。我们的研究结果表明，耳迷走神经刺激在中枢神经系统中的投射可能也会影响皮质脊髓束。
