Pupillary Responses During Ophthalmodynamometry

Archives of Ophthalmology, 1963
Introduction The loss of a direct pupillary reflex to light with retention of the consensual reflex is a classic finding in unilateral blindness. It should follow that identical results would occur when an eye is rendered nonseeing by ophthalmodynamometry.

The narcoleptic cognitive pupillary response

IEEE Transactions on Biomedical Engineering, 2001
It has been reported that narcoleptics exhibit deficits in short-term memory, list recall, and stimulus frequency estimation compared with control subjects. It is also well-known that pupil dilation during cognitive tasks is a measure of subject attention state. Here we present results from six narcoleptics and six controls, a total of 360 experimental

Latency of the pupillary response

IEEE Transactions on Biomedical Engineering, 1988
The authors give an explanation of pupillary latency in terms of nonminimum phase lag. Minimum phase lag is that phase associated with a simple linear lag element; nonminimum phase is associated with a true delay element modeled as exp (-ST). Latency can be accurately modeled by a delay element.

Pupillary response to chromatic flicker

Experimental Brain Research, 2001
There is significant evidence for higher-level cortical control of pupillary responses to visual stimuli, suggesting that factors other than luminance changes may induce a pupillary response. In the present study, the pupillary responses to equiluminant flickering stimuli in a range of 3-13 Hz were examined.

The elasmobranch pupillary response

Vision Research, 1971
Abstract The rate and extent of the pupillary response to light and darkness were determined for a variety of sharks and rays. Dilation required 1–60 min and constriction 1–30 min, depending on the species. All responses were non-consensual. The dilator muscle was controlled by the third cranial nerve, which probably exerts a constant dilatory tonus ...

Bell's Palsy and Pupillary Response

Acta Oto-Laryngologica, 1985
Pupillary response was measured with binocular pupillogram to analyze Bell's palsy through examination of autonomic nerve function. This analysis was performed in 166 patients of Bell's palsy who consulted within one month after onset. Based on the results of pupillary response measurement, autonomic nerve function was normal in 54 patients, and ...

Lateral Asymmetries of Pupillary Responses

Cortex, 1998
We wanted to learn if pupillary changes induced by looking and attending to stimuli on the right and left are asymmetrical. In humans, there are hemispheric asymmetries in the control of attention-arousal systems. Because attention and arousal may influence pupil size, asymmetric pupillary responses may be seen when looking and attending in different ...

Conditioning the Human Pupillary Response

Perceptual and Motor Skills, 1968
Research on classical conditioning of human pupillary responses is reviewed and evaluated. Es have usually employed an auditory CS with illumination change as the UCS. While positive findings were reported in early studies, later investigators generally met with little success both in replications and in more sophisticated designs.

Auditory-pupillary responses in deaf subjects

Journal of Vestibular Research, 2010
Pupillary dilation in response to sound stimuli is well established and is generally considered to represent a startle reflex to sound. We believe that the auditory-pupillary response represents not only a simple startle reflex to sound stimuli but also represents a reaction to stimulation of other sense organs, such as otolith organs.
