The region of cortex over which transcranial magnetic stimulation (TMS) can delay saccadic eye movement was investigated. With TMS delivered in the reaction time foreperiod of auditory-triggered saccades, saccade onset could be delayed by up to 60 ms. The area of cortex over which TMS could delay saccade onset was located near the inter-aural line, approximately 6 cm lateral to the vertex, and was situated between areas over which TMS could generate motor evoked potentials in muscles of the hand and face. It is concluded that this area corresponds to the human frontal eye field and is closely associated with the motor strip, at a level between the representations of the hand and the face, and that stimulation of this region can interfere with the programming and execution of externally triggered saccades.
研究了经颅磁刺激（TMS）能够延迟眼球扫视运动的大脑皮层区域。在听觉触发扫视的反应时前周期施加TMS，扫视起始可延迟多达60毫秒。TMS能够延迟扫视起始的皮层区域位于耳间线附近，距头顶约6厘米外侧，且位于TMS能够在手部和面部肌肉中产生运动诱发电位的区域之间。得出的结论是，该区域对应于人类额叶眼区，并且与运动带紧密相关，处于手部和面部表征之间的水平，并且对该区域的刺激会干扰外部触发扫视的编程和执行。
