Newly discovered windows of brain plasticity may help with treatment of stress-related disorders
Chronic stress can lead to changes in neural circuitry that leave the brain trapped in states of anxiety and depression. But even under repeated stress, brief opportunities for recovery can open up, according to new research at The Rockefeller University. “Even after a long period of chronic st...
Study links epigenetic processes to the development of the cerebellar circuitry
From before birth through childhood, connections form between neurons in the brain, ultimately making us who we are. So far, scientists have gained a relatively good understanding of how neural circuits become established, but they know less about the genetic control at play during this crucial d...
New research explores how the fly brain reroutes odor information to produce flexible behavior
Some responses come automatically, like reflexes. Others vary with circumstance and experience. A once-delicious smell can be easily overlooked during a stressful moment or when it calls to mind a bout of food poisoning, for instance. This happens because, within the brain, molecules known as neu...
Mosquitoes are tuned to seek out temperatures that match warm-blooded hosts
Many animals gravitate towards heat, most often to regulate their own body temperatures. In rare cases, certain species—ticks, bedbugs, and some species of mosquitoes—seek out heat for food. For female mosquitoes, finding heat is essential for survival, as they need to feast on warm-blooded prey...
In the News - Scientific American - Greengard turns 90
A Nobel Laureate Turning 90 Continues to Churn Out Ideas for New Drugs   "Paul Greengard has been busy. In August he co-authored a paper on molecules that appear to regulate genes that might protect against Parkinson’s. That same month he took the lead on another paper that describes a protei...
Helen Hobbs receives Rockefeller’s Pearl Meister Greengard Prize
by Katherine Fenz, media relations manager Helen Hobbs, a cardiology researcher, received the 2015 Pearl Meister Greengard Prize during a festive event in the Caspary Auditorium last month. The award, which Dr. Hobbs received for her pioneering research into the genetics of high cholesterol and ...
New research helps to explain how temperature shifts the circadian clock
For many living things, a roughly 24-hour internal clock governs the rhythms of life—everything from sleep in animals, to leaf opening in plants and reproduction in bread mold. Scientists have come to understand much about this internal time-keeping system, but one important aspect, its complex r...
Study reveals new mechanism in nicotine addiction
Part of the reason people find smoking difficult to quit is that each time they have a cigarette, feelings of craving, irritability and anxiety melt away. This component of addiction is known as negative reward and is controlled in part by a region of the brain called the habenula. The neurotrans...
In the News - STAT - McEwen
There's no such thing as a male or female brain, study finds   "These results add to a complex picture that you’d never guess from media accounts and pop psych books. After decades of research, 'we’re still debating the question of whether there are sex differences in the [human] brain and ...
A newly discovered signaling molecule helps neurons find their way in the developing brain
During embryonic development, billions of neurons nimbly reposition themselves within the brain and spinal cord, and connect branches to form the neural circuits that ultimately control our movements, perception, and memory. Scientists have long sought to understand the driving forces in this met...
