Stopping a receptor called 'nogo' boosts the synapses 
Scientists have found that reducing the nogo receptor in the brain results in stronger brain signaling in mice, effectively boosting signal strength between the synapses, the connections between nerve cells in the brain. The ability to enhance such connections is central to the brain’s ability to rewire, a process that happens constantly as we learn and remember.

Does stress damage the brain?
Individuals who experience military combat obviously endure extreme stress, and this exposure leaves many diagnosed with the psychiatric condition of post-traumatic stress disorder, or PTSD. PTSD is associated with several abnormalities in brain structure and function.

Problems getting around in old age? Blame your brain
New research shows how well people get around and keep their balance in old age is linked to the severity of changes happening in their brains. The study is published in the March 18, 2008, issue of Neurology®, the medical journal of the American Academy of Neurology. White matter changes, also called leukoaraiosis, are frequently seen in older people and differ in severity.

Researchers discover second depth-perception method in brain
It’s common knowledge that humans and other animals are able to visually judge depth because we have two eyes and the brain compares the images from each. But we can also judge depth with only one eye, and scientists have been searching for how the brain accomplishes that feat.

Potential Alzheimer's disease drug target identified by UC San Diego researcher
In findings with the potential to provide a therapy for Alzheimer’s disease patients where none now exist, a researcher at the University of California, San Diego and colleagues have demonstrated in mice a way to reduce the overproduction of a peptide associated with the disease.

Pain receptor in brain may be linked to learning and memory
Scientists have long known that the nervous system receptor known as TRPV1 can affect sensations of pain in the body. Now a group of Brown University scientists has found that these receptors – a darling of drug developers – also may play a role in learning and memory in the brain.

Emotional 'bummer' of cocaine addiction mimicked in animals
Cocaine addicts often suffer a downward emotional spiral that is a key to their craving and chronic relapse. While researchers have developed animal models of the reward of cocaine, they have not been able to model this emotional impact, until now.

Diesel exhaust inhalation stresses your brain
If the smell of diesel exhaust isn't enough to make you avoid getting a lungful, new research now shows that even a short exposure to the fumes can affect your brain. A study published in the open access journal Particle and Fibre Toxicology reveals that an hour of sniffing exhaust induces a stress response in the brain's activity.

Scientists determine structure of brain receptor implicated in epilepsy and pre-menstrual tension
Scientists funded by the Biotechnology and Biological Sciences Research Council (BBSRC) have published new research in the journal Molecular Pharmacology identifying the structure of a receptor in the brain implicated in conditions such as epilepsy and pre-menstrual tension. The same receptor has also been reported to be highly sensitive to alcohol.

New study reveals profound impact of our unconscious on reaching goals
Whether you are a habitual list maker, or you prefer to keep your tasks in your head, everyone pursues their goals in this ever changing, chaotic environment. We are often aware of our conscious decisions that bring us closer to reaching our goals, however to what extent can we count on our unconscious processes to pilot us toward our destined future?

Brain network linked to contemplation in adults is less complex in children
A brain network linked to introspective tasks -- such as forming the self-image or understanding the motivations of others -- is less intricate and well-connected in children, scientists at Washington University School of Medicine in St. Louis have learned. They also showed that the network establishes firmer connections between various brain regions as an individual matures.

Paradoxical Alzheimer's Finding May Shed New Light on Memory Loss
Who'd a thunk? Younger brains show evidence of more memory loss than those with Alzheimer's. But those younger brains are also making memories faster than they lose them. A Buck Institute study shows that normal memory loss is hyperactivated in Alzheimer's, pointing to AD as a syndrome affecting the plasticity or malleability of the brain.

Neural progenitor cells as reservoirs for HIV in the brain
Impaired brain function is a prominent and still unsolved problem in AIDS . Shortly after an individual becomes infected with HIV, the virus can invade the brain and persist in this organ for life. Many HIV-infected individuals experience disturbances in memory functions and movement, which can progress to serious dementia. How the virus causes brain disease is still unclear.
