Scientists provide new evidence for cellular cause of SIDS
...iates movement or crying. "Gasping is an important arousal or auto-resuscitation mechanism," Ramirez said. It resets a baby's normal breathing rhythm and also alerts the baby as well as the mother that something is wrong. "During normal breathing, it's a complicated network. However, the network becomes more...How the brain learns to become addicted
...euroscientist Roy Wise commented that "Inasmuch as arousal or stress can trigger drug-seeking in drug-free animals, the neuroadaptations discovered by the Bonci group are important not only for how rewarding the drug is after an animal starts taking it, but, perhaps more importantly, for how likely the anima...Stress interferes with problem-solving; Beta-blocker may help
...ome to modulatory neurons that affect the state of arousal associated, in these cases, with stress. The state of arousal results from the release of the stress hormone norepinephrine, the action of which is blocked by the...Study continues the debate on the nature of bisexual men

...Prolonged increased neural activity in the brain's arousal centers triggers the release of adenosine, which in turn slows down neural activity in the arousal center areas. Because the arousal centers control activity throughout the entire brain, the process ...Unconventional brain circuits offer clues to insomnia-obesity connection
