Cortical modulation of pupillary function: systematic review [PDF]
PeerJ, 2019 Background The pupillary light reflex is the main mechanism that regulates the pupillary diameter; it is controlled by the autonomic system and mediated by subcortical pathways.

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.

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).

Estimation of operators’ fatigue using optical methods for determination of pupil activity
International Journal of Occupational Medicine and Environmental Health, 2015 Introduction The purpose of this study was to develop and initially validate an objective, yet quick, method for assessment of human fatigue. This aim can be achieved by the use of an optical, non-contact method of analysis of pupil activity.

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 ...

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.
