Pupillary responses to single and sinusoidal light stimuli in diabetic patients
Neurology International, 2009 We examined effects of diabetes mellitus (DM) on the pupillary light reflex (PLR). Phasic pupillary response to a single light stimulus (200 ms) (pPLR) and to continuous sinusoidal stimuli with four different frequencies (0.1, 0.3, 0.7, 1.3Hz) (cPLR ...

RdgB2 is required for dim-light input into intrinsically photosensitive retinal ganglion cells. [PDF]
, 2015 A subset of retinal ganglion cells is intrinsically photosensitive (ipRGCs) and contributes directly to the pupillary light reflex and circadian photoentrainment under bright-light conditions.

Comparing two captive bolt devices on market age Pekin ducks
Journal of Applied Poultry Research, 2021 Summary: The objective of this study was to determine the efficacy of 2 captive bolt devices in the euthanasia of market age Pekin ducks. One hundred twenty ducks were euthanized using either a commercially available captive bolt device (Zephyr-EXL, n ...

Regulatory effects of blood constituents on the function and metabolism of the cat brain in perfusion ezperiments. Brain perfusion with artificial blood containing low molecular dextran and amino acids [PDF]
, 1967 As a link in a series of studies on the effects of blood constituents on the brain function by means of brain perfusion, we used four kinds of artificial blood; namely, the blood containing a low molecular dextran, one containing glutamic acid, one ...

The pupillary light response reveals the focus of covert visual attention. [PDF]
PLoS ONE, 2013 The pupillary light response is often assumed to be a reflex that is not susceptible to cognitive influences. In line with recent converging evidence, we show that this reflexive view is incomplete, and that the pupillary light response is modulated by ...

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.

Investigation of light-induced lacrimation and pupillary responses in episodic migraine.
PLoS ONE, 2020 The purpose of this pilot study was to investigate the light-induced pupillary and lacrimation responses mediated by intrinsically photosensitive retinal ganglion cells (ipRGCs) in migraine.
