A new study found that over half of US adults experienced some form of discrimination, and individuals with high exposure to discrimination have more than five times the chances of screening positive for depression, and five times the chances of screen…

Scientists have confirmed a neurobiochemical link between dopamine and cognitive flexibility. PET imaging shows that the brain increases dopamine production when completing cognitively demanding tasks, and that the more dopamine released, the more effi…

People who have early signs of heart problems may also have changes in brain health that can be early signs of dementia, such as loss of brain volume, according to a meta-analysis. The meta-analysis does not prove that early heart problems cause loss o…

A research team says high blood sugar levels appear to weaken function in key part of brain, mimicking Alzheimer’s.

Two specific genes that evolve exclusively in humans jointly influence the development of the cerebrum. Researchers have provided evidence that these genes contribute together to the evolutionary enlargement of the brain.

Scientists have gained greater clarity in the brain regions and neurons that control metabolism, body temperature and energy use. A team of researchers discovered which chemicals influence the signals that control how much energy the body uses. Researc…

A research team has uncovered a fundamental principle of how the brain prioritizes vision and hearing differently depending on whether we are still or in motion. The study provides new insights into how movement alters the brain’s sensory decision-maki…

Researchers have found a unique molecular signature and genes in the orbitofrontal cortex associated with heroin-seeking behavior. A preclinical rodent model implicated a gene called Shisa7 as the key predictor. A new study provides valuable insights i…

The body’s cells respond to stress — toxins, mutations, starvation or other assaults — by pausing normal functions to focus on conserving energy, repairing damaged components and boosting defenses. If the stress is manageable, cells resume normal act…

Research has shown that a biological brain mechanism called the ‘kynurenine pathway’ is imbalanced in adolescents with depression, and this imbalance is more pronounced in teenage girls than boys.
