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.

Are there predictive pupillometry markers in determining external ventricular device (EVD) weaning failure or success in subarachnoid hemorrhage patients? [PDF]
, 2018 Pupillometers objectively measure constriction (i.e., parasympathetic pathwy) and dilation (i.e., sympathetic pathway) velocities of the pupillary reflex.

Medical management of hereditary optic neuropathies. [PDF]
, 2014 Hereditary optic neuropathies are diseases affecting the optic nerve. The most common are mitochondrial hereditary optic neuropathies, i.e., the maternally inherited Leber's hereditary optic neuropathy (LHON) and dominant optic atrophy (DOA).

Melanopsin-expressing retinal ganglion cells are resistant to cell injury, but not always [PDF]
, 2017 Melanopsin retinal ganglion cells (mRGCs) are intrinsically photosensitive RGCs deputed to non-image forming functions of the eye such as synchronization of circadian rhythms to light-dark cycle.

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 ...

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 ...

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 ...

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 ...

Comparison of the qCON and qNOX indices for the assessment of unconsciousness level and noxious stimulation response during surgery [PDF]
, 2016 The objective of this work is to compare the performances of two electroencephalogram based indices for detecting loss of consciousness and loss of response to nociceptive stimulation.
