Abstract Non‐image forming (NIF) pathways, a specialized branch of retinal circuitry, play crucial role supporting physiological and behavioral processes, including circadian rhythmicity. Among the NIF regions, dorsal raphe nucleus (DRN), midbrain serotonergic cluster neurons, is also devoted to functions. Despite indirectly send photic inputs centers modulating their activities, little known about organization retina‐DRN circuits in primate species. To enhance our understanding intrinsic...
ABSTRACT The physiological aging process is well known for functional decline in visual abilities. Among the components of system, dorsal lateral geniculate nucleus (DLG) and superior colliculus (SC) provide a good model investigations, as these structures constitute main pathways retinal inputs reaching cortex. However, there are limited data available on quantitative morphological neurochemical aspects DLG SC across lifespan. Here, we used optical density to determine immunoexpression...
In mammals, the suprachiasmatic nucleus (SCN) and intergeniculate leaflet (IGL) are main components of circadian timing system. The SCN, classically known as master clock, generates rhythms synchronizes them to environmental cues. IGL is a key structure that modulates SCN activity. Strategies on use time by animals can provide important clues about how some species adapted competitive process in nature. Few studies have provided information temporal niche bats with special attention neural...
The aging effects on circadian rhythms have diverse implications including changes in the pattern of rhythmic expressions, such as a wide fragmentation rhythm rest-activity and decrease amplitude activity regulated by suprachiasmatic nucleus (SCN). study blue light biological aspects has received great current interest due, among some aspects, to its positive psychiatric disorders humans. This aims evaluate effect therapy SCN functional through evaluation rhythm, rats. For this, 33...
