Researchers at the Stanford University School of Medicine have found that formoterol ̶  an FDA-approved drug for treating asthma and similar respiratory disorders ̶  improves cognitive function in mice genetically altered to exhibit symptoms of Down syndrome including cognitive disability.   Formoterol was chosen for the study because it activates β2 adrenergic receptors (β2ARs) on neurons, a task also carried out by norepinephrine, a neurotransmitter with a...

In spring, days grow long, and the white-footed mouse looks for a mate. For some mammals, day length prompts behaviors like breeding or camouflaging, and scientists say it's not just the arc of the sun that kicks off these seasonal events; substances in the brain also play a part.   One important element is melatonin, a hormone that the mammalian brain secretes at night. According to a...

Drugs affect different people in different ways. Take cocaine for example. Not only does the drug have a stronger impact on the behavior of individuals with a particular genetic makeup, it also  initiates more profound changes in their brains.   Researchers at the University of Michigan are studying brain plasticity in cocaine-treated rats after a period of abstinence. They're studying how abstinence from the drug affects different...

Sensory stimuli are all around us. Street traffic zooms by. A neighbor waves “hello.” A co-worker taps away at his keyboard. Each sight, sound, and motion ignite action within our brains. But even without all these stimuli, the brain is always active.   Known as “spontaneous activity,” the activity happening inside the brain in the absence of direct stimuli follows a pattern of up and down states...
