Research on somatosensory cortical responses by the electromagnetic recording method

采用电磁记录法，对电刺激正中神经或手指后的体感皮层反应进行了非侵入性研究。我们，第一次，成功地可视化冲动传播沿着纤维从丘脑到体感皮层的平均传导速度为29米/秒。此外，我们已经表明，600 Hz的高频振荡（HFO），覆盖初始皮层活动，反映了抑制性中间神经元的功能，在初级体感皮层的体感信息处理的初始步骤。

Somatosensory cortical responses following electrical stimulation to the median nerve or finger were studied non-invasively by the electromagnetic recording method. We, for the first time, succeeded in visualizing impulse propagations along the fibers from the thalamus to the somatosensory cortex with the mean conduction velocity of 29 m/s. Also, we have shown that the 600 Hz high frequency oscillations (HFOs), overlying initial cortical activity, reflect the function of inhibitory interneurons as the initial step of somatosensory information processing in the primary somatosensory cortex.
