Saliency and priority modulation in a pop-out paradigm: Pupil size and microsaccades
Chin-An Wang, Jeff Huang, Donald C.Brien, Douglas P. Munoz
We investigated saliency and priority modulation in multiple components of the orienting response in a pop-out paradigm. Larger pupil responses were produced in the pop-out condition than in other control conditions after stimulus presentation. Microsaccade direction was biased toward the pop-out item when it was the subsequent saccadic target. The midbrain superior colliculus is coordinating these behaviors because of its central role in orienting behavior including pupil size and microsaccades.
