Quitting alcohol changes the brain and can increase the risk of compulsive drinking—new research in mice
For some, abstaining from alcohol can subsequently increase compulsive drinking. Our research team found that, in abstaining mice, this urge to drink is preceded by changes in the activity of a particular brain region, pointing ...

Brain cancer cells exploit normal nerve signaling to multiply and invade, new study finds
Gliomas are malignant brain tumors that originate from glial cells, which do not produce electrical impulses like neurons but instead support neurons by maintaining their structure and function. They are the most common form ...
Food decisions in anorexia engage brain region tied to inflexible habits, study finds
Individuals with anorexia nervosa restrict food intake, sometimes to the point of starvation. Yet a new study published in The Journal of Neuroscience finds that the cognitive machinery they use to make decisions about what ...

More than half of hippocampal synapses vanish, yet mouse memories remain intact
How do we remember the distant past? For decades, scientists have believed synaptic potentiation—the adaptive strengthening of our brain's cellular connections—to be the key to memory retention. Researchers from the Okinawa ...

Brain circuit keeps tabs on what just happened to aid judgment of what's happening now
A brain must constantly cope with the highly variable, fast-paced nature of the world when trying to judge what's going on around it. On the one hand, it has to be open to whatever new sensory information may come its way, ...

New brain map connects mice and primates to strengthen medical research
Most neuroscience research still runs on mice, even though much of what applies to mice does not hold up in humans. Marmosets have emerged as a bridge between species. However, comparing the brains of mice and marmosets runs ...
