我们将在麻醉前和麻醉后连续测试五名正常志愿者, 前臂的正中神经桡神经和尺神经 非侵入性磁 将在不同的头皮位置上传递刺激。 如果我们检测到 招募的α运动神经元池扩大, 肌肉的代表区域直接接近水平, 麻醉(肱二头肌,三角肌),这将表明揭露先前存在的 连接,因为没有新的突触可以在这么短的时间内建立。 这将提供关于重组机制的宝贵信息 中枢神经系统的损伤。
英文摘要
We will test five normal volunteers before and serially after anesthesia of the median, radial and ulnar nerves at the forearm. Noninvasive magnetic stimulation will be delivered over different scalp positions. If we detect enlargement of the alpha motoneuron pool recruited and the motor representation areas for muscles immediately proximal to the level of anesthesia (biceps, deltoid), it would indicate unmasking of preexistent connections, since no new synapses can be established in such a short time. This would provide valuable information on the mechanisms of reorganization of human central nervous system following deafferentation.
