Learning from the pupil: a spatial visual channel in the absence of V1 in monkey and human.

Abstract:

The pupil of the normal human subject constricts in response not only to average increases in light energy, but also selectively to the spatial structure of a visual stimulus even when there are no energy changes. This enables one to measure visual acuity and sensitivity as a function of spatial frequency. It is known that pupillometric measures of acuity correlate well with those determined psychophysically for normal human observers. The purpose of the present study was to measure pupillary...
