Sign Up to like & getrecommendations! Published in 2017 at "JAMA Neurology"
DOI: 10.1001/jamaneurol.2016.5131
Abstract: Importance A neurophysiologic signature of the melanopsin-mediated persistent constriction phase of the pupillary light reflex may represent a surrogate biomarker for the integrity of the retinohypothalamic tract, with potential utility for investigating alterations in homeostatic… read more here.

DOI: 10.1007/s00417-018-4189-0
Abstract: Dear Editor, Pupil perimetry is becoming more common for its utility as an objective method to evaluate visual fields using pupillary response. The pupillary response has two main pathways: an afferent and an efferent limb.… read more here.

DOI: 10.1167/jov.22.7.7
Abstract: Measuring pupillary response is a prevalent technique to evaluate mental states. It is indispensable to conduct a correction procedure for the pupillary baseline to get a meaningful conclusion from the pupillary response. However, the relationship… read more here.

DOI: 10.3389/fbioe.2021.617028
Abstract: Background: Individuals with Parkinson’s disease (PD) may need to spend more mental and physical effort (i.e., cognitive workload) to maintain postural control. Pupillary response reflects cognitive workload during postural control tasks in healthy controls but… read more here.

DOI: 10.3389/fnhum.2017.00209
Abstract: Clinically, meditative practices have become increasingly relevant, decreasing anxiety in patients and increasing antibody production. However, few studies have examined the physiological correlates, or effects of the incorporation of meditative practices. Because pupillary reactivity is… read more here.
