If the eye-position signal during visually-evoked saccades is dependent on the dorsomedial frontal cortex (DMFC), one would expect that saccades generated to briefly presented visual targets would be disrupted after displacement of the eyes via electrical stimulation of this cortical area. Compared are compensatory saccades evoked to brief targets following stimulation of the DMFC and frontal eye fields (FEF). Compensatory saccades produced to brief targets following perturbation via the DMFC were not affected. Accordingly, electrical stimulation of the DMFC does not disrupt the eye-position signal during the execution of visually-evoked saccades.
如果视觉诱发扫视期间的眼位信号依赖于背内侧前额叶皮质（DMFC），那么人们会预期，在通过电刺激该皮质区域使眼睛移位后，对短暂呈现的视觉目标产生的扫视会受到干扰。比较了刺激DMFC和额叶眼区（FEF）后对短暂目标诱发的代偿性扫视。通过DMFC进行扰动后对短暂目标产生的代偿性扫视未受影响。因此，在执行视觉诱发扫视期间，对DMFC的电刺激不会干扰眼位信号。
