在10例慢性单侧损伤患者中研究了外侧前额叶皮层在将感知转换为行动中的作用。他们在视觉显示的中心识别颜色，而在同病灶或对病灶区域同时呈现侧翼的干扰物颜色。侧翼可以是与目标相同的颜色，或者与正确的反应不相容。相容和不相容的侧翼对反应时间（RT）的影响作为侧翼激活反应通道的量度。在contralesional领域的侧翼影响RT比那些在同病灶领域。这些结果表明，外侧前额叶皮层参与维持刺激反应通道。
The role of lateral prefrontal cortex in transducing perception into action was studied in 10 patients with chronic, unilateral lesions. They identified colors in the center of a visual display, while a flanking, distractor color was presented simultaneously in either the ipsilesional or contralesional field. The flanker could be either the same color as the target, or incompatible with the correct response. The effects of compatible and incompatible flankers on reaction time (RT) served as a measure of response channel activation by the flanker. Flankers in the contralesional field influenced RT less than did those in the ipsilesional field. These results suggest that the lateral prefrontal cortex is involved in maintaining stimulus-response channels.
