From sound science to sound sleep New research from the University of Toronto could provide some restful nights for the 18 million North Americans who suffer from obstructive sleep apnea. In a recent study that appeared in the Journal of Neuroscience, scientists from the University demonstrated that repeated obstruction of the airways requires release of the brain chemical noradrenaline. The release of this chemical helps the brain learn to breathe more effectively and purposefully. "What we...

Virginia Tech Carilion Research Institute faculty member leads study resulting in new insight on rehabilitating brain function in addicts People with addictions to stimulants tend to choose instant gratification or a smaller but sooner reward over a future benefit, even if the future reward is greater. Reduced value of a future reward, called "delay discounting" by neuroscientists, is the major challenge for treatment of addiction. A new study in the February 2011 (Vol. 69, Issue 3)...

An Inserm research team in Toulouse, led by Dr Stein Silva (Inserm Unit 825 "Brain imaging and neurological handicaps"), working with the "Modelling tissue and nociceptive stress" Host Team (MATN IFR 150), were interested in studying the illusions described by many patients under regional anaesthetic. In their work, to be published in the journal Anesthesiology, the researchers demonstrated that anaesthetising an arm affects brain activity and rapidly impairs body perception. The ultimate aim...

Research conducted by Iaroslav Savtchouk, a graduate student, and S. June Liu, PhD, Associate Professor of Cell Biology and Anatomy at LSU Health Sciences Center New Orleans, has shown that a single exposure to acute stress affected information processing in the cerebellum "“ the area of the brain responsible for motor control and movement coordination and also involved in learning and memory formation. The work is published in the January 12, 2011 issue of The Journal of Neuroscience....

Yale University researchers have found that a single molecule not only connects brain cells but also changes how we learn. The findings, reported in the December 9 issue of the journal Neuron, may help researchers discover ways to improve memory and could lead to new therapies to correct neurological disorders. The junctions between brain cells over which nerve pulses pass "” called synapses "” are crucial for regulating learning and memory and how we think. Aberrations in the...

Scientists from Germany, UK and Italy identify a molecular switch that leads to a sustained increase of calcium in nerve cells and plays a crucial role in the formation of memory and addictive behaviors. Learning and memory formation are based on the creation of new connections between neurons in the brain. Also, behaviors such as nicotine addiction manifest themselves in long-term changes of neuronal connectivity and can "“ at least in this respect "“ be viewed as a form of...

(Ivanhoe Newswire) -- Novel research from the shores of California has provided insight into mechanisms that trigger recovery after damage to the brain imperative for memory and attention.  This research highlights the role of undamaged sections of the brain that can "take over" and support the recovery function. "Brain damage" or "brain injury" (BI) is the destruction or degeneration of brain cells, often with an implication that the loss is significant in terms of functioning or...

New research provides fascinating insight into mechanisms that underlie recovery after damage to a region of the brain important for memory and attention. The research, published by Cell Press in the November 4th issue of the journal Neuron, highlights the role of undamaged portions of the brain that can "take over" and support the recovery of function. Brain damage can have devastating consequences, depending on the location and severity of the injury. Damage to an area of the brain called...

With the help of tiny, see-through fish, Stanford University School of Medicine researchers are homing in on what happens in the brain while you sleep. In a new study, they show how the circadian clock and sleep affect the scope of neuron-to-neuron connections in a particular region of the brain, and they identified a gene that appears to regulate the number of these connections, called synapses. "This is the first time differences in the number of synapses between day and night and between...

Addictive drugs are known to induce changes in the brain's reward circuits that may underlie drug craving and relapse after long periods of abstinence. Now, new research, published by Cell Press in the September 9 issue of the journal Neuron, uncovers a specific neural mechanism that may be linked to persistent drug-seeking behavior and could help to guide strategies for development of new therapies for cocaine addiction. Previous research has shown that the ventral tegmental area (VTA) is a...
