Influence of Light Exposure on the Melanopsin Driven Pupil Response and Circadian Rhythm
Exposure to increasing amounts of artificial light during the night may contribute to the high prevalence of reported sleep dysfunction. Release of the sleep hormone melatonin is mediated by the intrinsically photosensitive retinal ganglion cells (ipRGCs). ipRGCs signal environmental light, with …

MELANOPSIN AND PACAP IN INTRINSICALLY PHOTOSENSITIVE RETINAL GANGLION CELLS REGULATE THE DEVELOPMENT OF RETINOFUGAL PROJECTIONS IN MICE
… (ipRGCs) and express the photopigment melanopsin and the neuropeptide pituitary adenylate cyclase-activating polypeptide (PACAP). These cells project to brain nuclei to mediate a variety of visual behaviors involved in both non-image and image-forming functions, such as circadian …

New objective and psychophysical techniques to study the processing of visual signals with emphasis on chromatic afterimages
… purpose of the last study was to examine whether melanopsin contributes to the dynamic pupil light reflex responses in humans. A light source containing of four primary components was employed to generate pupillary stimuli that isolate luminance, colour or combined rod and melanopsin. Normal …

Influence of retinal states on the development and maintenance of retinofugal projections
… responses in PD mice was diminished. Reduced melanopsin signal in the retina, not downstream anomalies, explains this functional deficiency. These observations suggest that changes to eye-specific segregation are limited once projections are established, regardless of retinal activity or …

Circadian Disruption by Light at Night: Implications for Mood
… acts through specific retinal pathways involving melanopsin. Taken together, these studies demonstrate the consequences of LAN, but also outline potential avenues for prevention or intervention.

A Mixed Method Approach to Post-Awakening Cortisol Research: Exploring Associations with Post-Awakening Melatonin, Primary Open-Angle Glaucoma and Experiences of Participation
… the curve with reference to ground: AUCg. Via melanopsin containing retinal ganglion cells (mRGCs), upon awakening the hypothalamic suprachiasmatic nucleus (SCN) enhances cortisol secretion at wake, in response to light. The same projection of stimuli to the SCN also suppresses melatonin …
