Isoforms of Melanopsin Mediate Different Behavioral Responses to Light
Melanopsin (OPN4) is a retinal photopigment that mediates a wide range of non-image-forming (NIF) responses to light including circadian entrainment, sleep induction, the pupillary light response (PLR), and negative masking of locomotor behavior (the acute suppression of activity in response to light). How these diverse NIF responses can all be mediated by a single photopigment has remained a m...
متن کاملNerve and behavioral responses of mice to various umami substances.
Food contains various taste substances. Among them, umami substances play an important role with regard to the perception of the taste of food, but, few studies have examined the taste characteristics of representative umami substances other than monosodium L-glutamate (MSG). By conducting mouse behavioral studies (the 48-h 2-bottle preference test and the conditioned taste aversion test) and a...
متن کاملAltered circadian responses to light in streptozotocin-induced diabetic mice.
Diabetes mellitus affects the daily expression of many behavioral and metabolic processes. Recent studies indicate that changes in brain glucose metabolism alter the entraining effects of light of the circadian pacemaker. To test whether diabetes-associated diurnal changes are related to alterations in the responses of the circadian pacemaker to light, photic phase resetting of the circadian rh...
متن کاملReduced glucose availability attenuates circadian responses to light in mice.
To test whether circadian responses to light are modulated by decreased glucose availability, we analyzed photic phase resetting of the circadian rhythm of locomotor activity in mice exposed to four metabolic challenges: 1) blockade of glucose utilization induced by 2-deoxy-d-glucose (2-DG), 2) fasting (food was removed for 30 h), 3) insulin administration, and 4) insulin treatment after fastin...
متن کاملSpatial responses to light in mice with severe retinal degeneration.
It is known that mice homozygous for the retinal degeneration (rd) mutation are able to synchronize their circadian rhythms to light-dark cycles. In the present experiments mice were given a choice of a dark or an illuminated living and nesting area. C3H, CBA and C57 rd/rd mice spent more time in the dark than in the illuminated area. Also, they spent as much time in the dark area as did wildty...
