Renewed Attention on the Pupil Light Reflex

Trends Neurosci. 2017 Aug;40(8):455-457. doi: 10.1016/j.tins.2017.06.007. Epub 2017 Jul 7.


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.

Keywords: attention; frontal eye fields; prefrontal cortex; pupillary light reflex.
