本研究使用近红外光谱（NIRS）研究了成年人的前额叶激活与迷宫解决能力的关系。参与者被要求解决一个加号形状的迷宫，类似于鸽子和人类儿童用来评估计划过程的迷宫，通过移动一个目标正方形到一个显示在触摸屏上的目标正方形。当目标跳到另一只手臂的末端时，参与者对之前的目标立即做出了错误的反应，与之前的参与者相似，但频率比之前的参与者低，反应时间比他们正确调整反应时短。在这些错误的试验中，观察到相对较大的有两个峰的血流动力学变化，特别是在右侧额叶下皮层（IFC）附近的通道，这表明在犯错误后使用额外的认知资源来调整反应。除了显示成年人比以前的参与者有更好的行为抑制外，目前的近红外光谱数据表明，前额叶激活模式的差异取决于对未来计划的抑制是否有效。实验结果也证实了近红外光谱（NIRS）的有效记录，当参与者通过手指触摸显示器来移动计算机生成的刺激时。(C) 2010 Elsevier B.V.版权所有
The present study using near-infrared spectroscopy (NIRS) examined prefrontal activation associated with maze-solving performance in adult humans. The participants were required to solve a plus-shaped maze, comparable to the one used for pigeons and human children to behaviorally assess planning processes, by moving a target square to a goal square presented on a touch-sensitive screen. The participants made incorrect responses toward a previous goal immediately after the goal jumped to the end of another arm, in parallel with but less frequently than previous participants, with shorter reaction times than when they correctly adjusted their responses. In these incorrect trials, relatively larger hemodynamic changes having two peaks were observed, especially in channels near the right inferior frontal cortex (IFC), suggesting use of additional cognitive resources for adjustment of responses after making errors. In addition to showing human adults' better behavioral inhibition than previous participants, the present NIRS data suggest a difference in prefrontal activation patterns according to whether inhibition of the forward plan was working well or not. The results also testify to the effective NIRS recording, while the participants were moving a computer-generated stimulus by actually making finger touches to the monitor. (C) 2010 Elsevier B.V.
