Heavy marijuana use may lead to lower dopamine release in the brain

In a recent study, researchers found evidence of a compromised dopamine system in heavy users of marijuana. Lower dopamine release was found in the striatum - a region of the brain that is involved in working memory, impulsive behavior, and attention. Previous studies have shown that addiction to other drugs of abuse, such as cocaine and heroin, have similar effects on dopamine release, but such evidence for cannabis was missing until now.

Slow-wave sleep may promote consolidation of recent memories

Research strongly suggests that sleep, which constitutes about a third of our lives, is crucial for learning and forming long-term memories. But exactly how such memory is formed is not well understood and remains, despite considerable research, a central question of inquiry in neuroscience.

Inflammation after stroke may help the brain to self-repair

After a stroke, there is inflammation in the damaged part of the brain. Until now, the inflammation has been seen as a negative consequence that needs to be abolished as soon as possible. But, as it turns out, there are also some positive sides to the inflammation, and it can actually help the brain to self-repair.

NeuroLife device helps paralyzed man to perform complex functional movements

Six years ago, he was paralyzed in a diving accident. Today, he participates in clinical sessions during which he can grasp and swipe a credit card or play a guitar video game with his own fingers and hand. These complex functional movements are driven by his own thoughts and a prototype medical system that are detailed in a study published online today in the journal Nature.

Interdisciplinary researchers to explore ethical issues of pregnant women during Zika crisis

The emerging Zika virus epidemic is bringing to light a longstanding ethical challenge in medical research: the inclusion of pregnant women. With new funding from the Wellcome Trust, an interdisciplinary team of scholars will focus on issues of ethics and research in pregnancy and women of reproductive age, beginning with the current Zika context and later expanding to general public health research.

High dosages of antihistamines have dulling effect on genes associated with post-exercise recovery

After vigorous exercise, some 3,000 genes go to work to aid recovery by boosting muscles and blood vessels, but in the presence of high doses of antihistamines almost 27 percent of the gene response is blunted, according to University of Oregon researchers.
