Abstract
We have recorded cerebral magnetic fields evoked by painful dental stimulation. The field pattern indicates a current source at the upper bank of the anterior Sylvian Fissure, corresponding to the anterior end of the secondary somatosensory cortex. This finding suggests cortical representation of tooth pulp in man. The neuromagnetic technique, allowing the investigation of this cortical area, thus provides a new non-invasive tool for pain research.
摘要
我们记录了牙科疼痛刺激诱发的脑磁场。磁场模式表明，电流源位于外侧裂前部上缘，对应于第二躯体感觉皮层的前端。这一发现提示了人类牙髓的皮层表征。神经磁技术能够对该皮层区域进行研究，从而为疼痛研究提供了一种新的非侵入性工具。
