Cephalochordate Melanopsin: Evolutionary Linkage between Invertebrate Visual Cells and Vertebrate Photosensitive Retinal Ganglion Cells [PDF]
Current Biology, 2005 Animal photoreceptor cells can be classified into two distinct types, depending on whether the photopigment is borne on the membrane of a modified cilium (ciliary type) or apical microvilli (rhabdomeric type) [1]. Ciliary photoreceptors are well known as vertebrate rods and cones and are also found in several invertebrates.

Light during darkness and cancer: relationships in circadian photoreception and tumor biology [PDF]
, 2006 The relationship between circadian phototransduction and circadian-regulated processes is poorly understood. Melatonin, commonly a circadian phase marker, may play a direct role in a myriad of physiologic processes.

Coral reef fish visual adaptations to a changing world
Functional Ecology, Volume 39, Issue 10, Page 2561-2572, October 2025.Read the free Plain Language Summary for this article on the Journal blog. Abstract Coral reef ecosystems show fluctuations in their prevailing light environment in response to both regular (e.g. between seasons) and more prevalent stochastic events (e.g. human‐induced sediment runoff).

PLoS ONE, 2015 Intrinsically photosensitive retinal ganglion cells (ipRGCs) are involved in circadian and other non-image forming visual responses. An open question is whether the activity of these neurons may also be under the regulation mediated by the neurohormone ...

Loss of Melanopsin-Expressing Ganglion Cell Subtypes and Dendritic Degeneration in the Aging Human Retina [PDF]
, 2017 In mammals, melanopsin-expressing retinal ganglion cells (mRGCs) are, among other things, involved in several non-image-forming visual functions, including light entrainment of circadian rhythms.

Acta Psychiatrica Scandinavica, Volume 152, Issue 3, Page 156-179, September 2025.ABSTRACT Introduction Bipolar disorder (BD), characterized by extreme mood shifts between mania and depression, can manifest in childhood, and pose treatment challenges. Treatment for full‐criteria BD I or II in children has been partially described in the literature, but major uncertainties exist regarding non‐classic presentations, which were ...

Loss of melanopsin-containing retinal ganglion cells in a rat glaucoma model
Chinese Medical Journal, 2008 Glaucoma can cause progressive damage to retinal ganglion cells. These cells can be classified as cells projecting to the superior colliculus and melanopsin-containing retinal ganglion cells, which project to the suprachiasmatic nucleus. This study was to investigate the effects of chronic intraocular pressure elevation on melanopsin-containing retinal

PLoS ONE, 2008 Non-image related responses to light, such as the synchronization of circadian rhythms to the day/night cycle, are mediated by classical rod/cone photoreceptors and by a small subset of retinal ganglion cells that are intrinsically photosensitive ...

EVOLUTION OF THE CIRCADIAN CLOCK IN EXTREME ENVIRONMENT: LESSONS FROM CAVEFISH. [PDF]
, 2010 Evolution has been strongly influenced by the daily cycles of temperature and light imposed by the rotation of the Earth. Fascinating demonstrations of this are seen in extreme environments such as caves where some animals have remained completely ...

Ocular changes as potential biomarkers for early diagnosis of Alzheimer's disease
Alzheimer's &Dementia, Volume 21, Issue 8, August 2025.Abstract Alzheimer's disease (AD) is a progressive neurodegenerative disorder and the most common cause of dementia. AD diagnosis often involves a thorough assessment, including clinical evaluation, cognitive testing, medical history examination, genetic testing, and biomarker analysis. Currently, the invasive nature and high costs of biomarker testing,
