Effect of ambient temperature on brain temperature and sleep-wakefulness in medial preoptic area lesioned rats.
The changes in brain temperature and sleep-wakefulness were studied in rats during their exposure to different ambient temperatures of 18 degrees C, 24 degrees C and 30 degrees C, before and after N-methyl D-aspartic acid lesion of the medial preoptic area. The medial preoptic area lesion produced a decrease in sleep, and increase in brain temperature except at 30 degrees C. Increase and decrea...
متن کاملWhy the medial preoptic area is important for sleep regulation.
The medial preoptic area (mPOA) is one of the many areas in the brain that control sleep. Apart from sleep, the mPOA is important for the regulation of body temperature, and other important body functions aimed at energy homeostasis. In sleep regulation, the major function of this area is to maintain sleep. Though the mPOA controls sleep and body temperature through independent neuronal circuit...
متن کاملEffects of Microinjections of Triazolam into Medial Preoptic Area on Sleep and Brain Temperature in Rats
A variety of hypnotic compounds including triazolam (1), pentobarbital (2) and ethanol (3) have been shown to induce sleep when microinjected into the medial preoptic area (MPA) of the anterior hypnothalamus. The mechanism by which they produce this effect, however, is not clear. Lesions of a basal forebrain area including the preoptic area decrease sleep (4), while electrical stimulation of th...
متن کاملSleep and Core Temperature Measures Following Microinjection of Muscimol into the Medial Preoptic Area in Rats
Anumber of compounds, including triazolam (1,2), pentobarbital (3), ethanol (4), and adenosine (5) have been shown to induce sleep when injected into the medial preoptic area of rats. The mechanism by which this occurs remains to be clearly elucidated, though the high affinity for triazolam for the benzodiazepine recognition site on the GABA-A-benzodiazepine receptor complex, and the interactio...
متن کاملGalanin neurons in the medial preoptic area govern parental behaviour
Mice display robust, stereotyped behaviours towards pups: virgin males typically attack pups, whereas virgin females and sexually experiencedmales and females display parental care. Here we show that virginmales genetically impaired in vomeronasal sensing do not attack pups and are parental. Furthermore, we uncover a subset of galanin-expressing neurons in the medial preoptic area (MPOA) that a...
