3124 Pupil dilation response to Tropicamid: a potential biological marker for Alzheimer's disease?
NEW ASPECTS ON THE FUNCTIONAL MORPHOLOGY OF THE CHOROID (E. Lbtjen-Drecoll, A. May) Department of Anatomy, University of Erlangen-Ntirnberg, Erlangen, Germany The structure of the choroid is essentially determined by the pattern of its vasculature and the newly described elastic-muscular system. This system fills the entire space between sclera and Btuch’s membrane, reaching from the ciliaty bo...
متن کاملThe pupil dilation response to visual detection
The pupil dilation reflex is mediated by inhibition of the parasympathetic Edinger-Westphal oculomotor complex and sympathetic activity. It has long been documented that emotional and sensory events elicit a pupillary reflex dilation. Is the pupil response a reliable marker of a visual detection event? In two experiments where viewers were asked to report the presence of a visual target during ...

متن کاملWhen a Dog is a Cat and How it Changes Your Pupil Size: Pupil Dilation in Response to Information Mismatch
In the present study, we investigate pupil dilation as a measure of lexical retrieval. We captured pupil size changes in reaction to a match or a mismatch between a picture and an auditorily presented word in 120 trials presented to ten native speakers of Swedish. In each trial a picture was displayed for six seconds, and 2.5 seconds into the trial the word was played through loudspeakers. The ...
متن کاملNeuromodulatory Correlates of Pupil Dilation
Pupillometry has long been used as a measure of brain state. Changes in pupil diameter are thought to coincide with the activity of neuromodulators, including noradrenaline and acetylcholine, producing alterations in the brain state and corresponding changes in behavior. Here we review mechanisms underlying the control of pupil diameter and how these mechanisms are correlated with changes in co...
