A circuit for pupil orienting responses: implications for cognitive modulation of pupil size

A circuit for pupil orienting responses: implications for cognitive modulation of pupil size

Highlights • Transient pupil dilation is evoked by the presentation of visual or auditory stimuli. • The evoked pupil responses are systematically modulated by stimulus saliency. • Similar transient pupil dilation is evoked by weak microstimulation of the SC. • SC projections to the pupil circuitry...

Beschreibung
Zusammenfassung:Highlights • Transient pupil dilation is evoked by the presentation of visual or auditory stimuli. • The evoked pupil responses are systematically modulated by stimulus saliency. • Similar transient pupil dilation is evoked by weak microstimulation of the SC. • SC projections to the pupil circuitry can mediate pupil modulation by cognitive processes.
