A circuit for pupil orienting responses: implications for cognitive modulation of pupil size.
Pupil size, as a component of orienting, changes rapidly in response to local salient events in the environment, in addition to its well-known illumination-dependent modulation. Recent research has shown that visual, auditory, or audiovisual stimuli can elicit transient pupil dilation, and the timing and size of the evoked responses are systematically modulated by stimulus salience. Moreover, w...

متن کاملPupil size reflects the focus of feature-based attention.
We measured pupil size in adult human subjects while they selectively attended to one of two surfaces, bright and dark, defined by coherently moving dots. The two surfaces were presented at the same location; therefore, subjects could select the cued surface only on the basis of its features. With no luminance change in the stimulus, we find that pupil size was smaller when the bright surface w...
متن کاملEffects of latanoprost and pilocarpine combination on the intraocular pressure and pupil size of normal rabbits
The aim of this study was to determine the combination effect of latanoprost and pilocarpine on theintraocular pressure and pupil size in normal rabbits. In this study, 18 rabbits were randomized to threegroups of 6 animals each. The right eyes of rabbits in group 1 were treated topically with latanoprost, ingroup 2 with pilocarpine and in group 3 with latanoprost and pilocarpine. The left eyes...
متن کاملAlerting, orienting or executive attention networks: differential patters of pupil dilations
Attention capacities, alerting responses, orienting to sensory stimulation, and executive monitoring of performance are considered independent yet interrelated systems. These operations play integral roles in regulating the behavior of diverse species along the evolutionary ladder. Each of the primary attention constructs-alerting, orienting, and executive monitoring-involves salient autonomic ...
