Addiction cravings may get their start deep in the right side of the brain

If you really want a drink right now, the source of your craving may be a pea-sized structure deep inside the right side of your brain, according to scientists.

Operational mechanism of the ‘acid-sensing ion channel’ that recognizes internal body pain

A research team has identified the pain transmission mechanism at the molecular level and presented new solutions for the understanding of pain signals and the development of pain treatments.

Caffeine and its analogues counteract memory deficits by normalizing stress responses in the brain

A new study describes the mechanism by which caffeine counteracts age-related cognitive deficits in animals. The study shows that the abnormal expression of a particular receptor — adenosine A2A, a target for caffeine — in the brain of rats induces a…

Psychopaths feel fear but see no danger

Researchers have found proof that psychopathic individuals can feel fear, but have trouble in the automatic detection and responsivity to threat.

Amputees’ brains remember missing hands even years later

Our brains have a detailed picture of our hands and fingers, and that persists even decades after an amputation, researchers have found. The finding could have implications for the control of next generation prosthetics.

Brain’s internal compass also navigates during imagination

When you try to find your way in a new place, your brain creates a spatial map that represents that environment. Neuroscientists now show that the brain’s ‘navigation system’ is not only active during actual or virtual movement, but also when ima…

People with alcohol dependency lack important enzyme

A research group has identified an enzyme whose production is turned off in nerve cells of the frontal lobe when alcohol dependence develops. The deficiency in this enzyme leads to continued use of alcohol despite adverse consequences.

Critical protein shows promise for the treatment of Alzheimer’s

In new research, researchers examine p62 — a critical protein associated with tell-tale symptoms of Alzheimer’s. The study demonstrates for the first time that p62 may have a role in reversing the effects of damaged plaques in the brain.

Use it or lose it: Stopping exercise decreases brain blood flow

Researchers examined cerebral blood flow in master athletes (ages 50-80 years) before and after a 10-day period during which they stopped all exercise. Using MRI brain imaging techniques, they found a significant decrease in blood flow to several brain…

Vesicles that trap amyloid appear to also contribute to Alzheimer’s

Vesicles, fluid-filled sacs that brain cells make to trap amyloid, a hallmark of Alzheimer’s, appear to also contribute to the disease, scientists report. Reducing the production of these vesicles, called exosomes, could help reduce the amount of amylo…
