Mapping neural networks to strengthen circadian rhythms If you’ve ever felt groggy the morning after traversing time zones, you can thank the temporary mismatch between your body’s 24-hour circadian rhythm and your new local time. In mammals, this rhythm is governed on a neuronal and hormonal level by the suprachiasmatic nucleus, a tiny region of the brain’s nestled directly above the two [...]

The odds that blacks will develop cognitive impairment, including dementia, in later life were 2.52 times greater than the [...]
The brain needs to ‘clean itself up’ so that it can ‘sort itself out’ When neurons die, their remains need to be eliminated quickly so that the surrounding brain tissue can continue functioning. A type of highly specialised cell known as microglia is responsible for this process which is called phagocytosis (derived from the Greek “phagein”, to eat, and “kitos”, cell). These tiny cells have numerous branches that are [...]
ADHD medication linked to slightly increased risk of heart rhythm problems Use of methylphenidate in children and young people with ADHD is associated with a slightly increased risk of abnormal heart rhythm (arrhythmia) shortly after the start of treatment, suggests research published by The BMJ today. Though the absolute risk is likely to be low, the researchers say the benefits of methylphenidate “should be carefully weighed [...]

Researchers find what could be brain’s trigger for binge behavior Rats that responded to cues for sugar with the speed and excitement of binge-eaters were less motivated for the treat when certain neurons were suppressed, researchers discovered. The findings suggest these neurons, in a largely unstudied region of the brain, are deeply connected to the tendency to overindulge in response to external triggers, a problem [...]

Clark’s top-tier research, published in Organizational Dynamics, shows that how a company presents its vision and values is deeply [...]
Maternal inflammation boosts serotonin, impairs fetal brain development in mice Fighting the flu during pregnancy sickens a pregnant woman, but it may also put the fetus at a slightly increased risk for neurodevelopmental disorders like autism later in life. A new study in pregnant mice offers a potential mechanism explaining why: Inflammation alters neurotransmitters and impairs growth of nerve cells in the developing fetal brain.
