New imaging technique shows how cocaine shuts down blood flow in mouse brains
A new method for measuring and imaging how quickly blood flows in the brain could help doctors and researchers better understand how drug abuse affects the brain, which may aid in improving brain-cancer surgery and tissue engineering, and lead to better treatment options for recovering drug addicts.

New mapping approach lets scientists zoom in and out as the brain processes sound
Researchers at Johns Hopkins have mapped the sound-processing part of the mouse brain in a way that keeps both the proverbial forest and the trees in view. Their imaging technique allows zooming in and out on views of brain activity within mice, and it enabled the team to watch brain cells light up as mice "called" to each other.

New tools help neuroscientists analyze big data
In an age of "big data," a single computer cannot always find the solution a user wants. Computational tasks must instead be distributed across a cluster of computers that analyze a massive data set together.

Discovery of New Drug Targets for Memory Impairment in Alzheimer's Disease
We are now a step closer to having a drug that can cure dementia and memory loss. Research team in Korea has discovered that reactive astrocytes, which have been commonly observed in Alzheimer's patients, aberrantly and abundantly produce the chief inhibitory neurotransmitter GABA and release it through the Best1 channel.

Seeing the inner workings of the brain made easier by new technique
Last year Karl Deisseroth, a Stanford professor of bioengineering and of psychiatry and behavioral sciences, announced a new way of peering into a brain- removed from the body- that provided spectacular fly-through views of its inner connections.

Damage in neurons from alcohol abuse identified for first time on the molecular level
Joint research between the University of the Basque Country (UPV/EHU) and the University of Nottingham has identified, for the first time, the structural damage caused at a molecular level to the brain by the chronic excessive abuse of alcohol.
