Early-life obesity impacts children’s learning and memory, study suggests

A new study found that children on the threshold of obesity or overweight in the first two years of life had lower perceptual reasoning and working memory scores than lean children when tested at ages five and eight. The study also indicated that IQ sc…

People with family history of alcoholism release more dopamine in expectation of alcohol

People with a family history of alcohol use disorder (AUD) release more dopamine in the brain’s main reward center in response to the expectation of alcohol than people diagnosed with the disorder, or healthy people without any family history of AUD, r…

Memory molecule limits plasticity by calibrating calcium

Researchers have for the first time identified a novel role for the CA2-enriched protein RGS14 and provided insights into the mechanism by which it limits plasticity. RGS14 seems to be special, acting as a molecular factor that puts the brakes on plast…

Leg exercise is critical to brain and nervous system health

New research shows that using the legs, particularly in weight-bearing exercise, sends signals to the brain that are vital for the production of healthy neural cells. The groundbreaking study fundamentally alters brain and nervous system medicine — gi…

Mice brain structure linked with sex-based differences in anxiety behavior

Using male individuals has long been a tradition in scientific mice studies. But new research enforces the importance of using a balanced population of male and female mice. Scientists studying the locus coeruleus brain structure in mice unexpectedly f…
