In a recent study, Ebitz and Moore described how subthreshold electrical microstimulation of the macaque frontal eye fields (FEF) modulates the pupillary light reflex. This elegant study suggests that the influence of the FEF and prefrontal cortex on attentional modulation of cortical visual processing extends to the subcortical circuit that mediates a very basic reflex, the pupillary light reflex.

重新关注瞳孔光反射

在最近的一项研究中，Ebitz 和 Moore 描述了猕猴额眼场 (FEF) 的阈下电微刺激如何调节瞳孔光反射。这项优雅的研究表明，FEF 和前额叶皮层对皮层视觉处理的注意力调制的影响延伸到皮层下回路，该回路介导了一个非常基本的反射，即瞳孔光反射。
