Researchers from the University of Missouri have found evidence of specific neurochemical changes associated with lower neuronal health in these brain regions. Further, they report that some of these changes in the brain may persist in individuals who receive hand transplants, despite their recovered hand function.
Even among non-dependent cocaine users, cues associated with consumption of the drug lead to dopamine release in an area of the brain thought to promote compulsive use, according to researchers at McGill University.
In this paper, the researchers report on a straightforward expression and purification protocol to obtain [U-15N] and [U-2H,13C,15N] Aβ42.
A biochemical self-destruct trigger found in many types of cells takes on a different role in brain cells infected with West Nile virus. In a turnabout, it guards the lives of these cells and calls up the body's defenses. Neurons might be protected by this otherwise self-demise mechanism because they are non-renewable and too important to kill off.
New research from the University of Liverpool, in collaboration with the Mario Negri Institute in Milan, published today in the Journal of Clinical Investigation, has identified a protein that could help patients with epilepsy respond more positively to drug therapies.
New research published online in The FASEB Journal sheds important light on the inner workings of learning and memory. Specifically, scientists show that a plasma membrane protein, called Efr3, regulates brain-derived neurotrophic factor-tropomyosin-related kinase B signaling pathway (BNDF-TrkB) and affects the generation of new neurons in the hippocampus of adult brains.
A region of the brain that helps to manage body functions including stress, heart rate and blood pressure reacts differently between men and women when presented with certain stimuli, according to a new study from the UCLA School of Nursing.
Studies have shown that loss of the sense of smell can be among the first warning signs of diseases such as Alzheimer's and Parkinson's. Now a researcher at the Perelman School of Medicine at the University of Pennsylvania wants to shift the search for clues about this process back even further, to find out if there is a common factor responsible for the loss of smell that may also serve as an early warning signal for a number of neurodegenerative diseases.
New research from the University of British Columbia confirms for the first time that even mild brain injury can result in impulse control problems in rats.
In classical computer science information is stored in bits, in quantum computer science -- in quantum bits, i.e. qubits. Experiments at the Institute of Physical Chemistry of the Polish Academy of Sciences in Warsaw prove that not only physics, but also chemistry is suitable for storing information. The role of the chemical bit, the 'chit', can be fulfilled by a simple arrangement of three droplets in contact with each other, in which oscillatory reactions occur.
