Monitoring Cognitive and Emotional Processes Through Pupil and Cardiac Response During Dynamic Versus Logical Task [PDF]

, 2010
The paper deals with the links between physiological measurements and cognitive and emotional functioning. As long as the operator is a key agent in charge of complex systems, the definition of metrics able to predict his performance is a great challenge.

The Pupillary Light Reflex in Borderline Diabetics

Journal of International Medical Research, 1989
Computerized IR videopupillography, using an open-loop photic stimulator, was used to compare the reflexes of borderline diabetics with overt non-insulin-dependent diabetics and with age- and sex-matched non-diabetic healthy controls. The patients were all male, aged 41–59 years.

Pupillary Size and Light Reflex in Premature Infants [PDF]

Neuro-Ophthalmology, 2015
The authors examined pupillary light reflexes to both red and blue stimuli using infrared video-pupillography in premature infants. Pupillary light reflexes were obtained in response to 470 nm blue and 635 nm red stimuli with varying intensities of 10 cd/m2 and 100 cd/m2. Red stimuli did not evoke a pupillary response in premature infants.
