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.

An adult brain affected by attention deficit disorder with or without hyperactivity (ADHD) presents modifications similar to those observed in individuals suffering from dementia. These are the findings of a study which shows that, compared with health…

Researchers developed olfactory tests — in which participants sniff odor labels that have been placed on a card — to assess people’s ability to discriminate, identify and remember odors. They found that participants could successfully take the test a…

If you’ve ever noticed how memories from the same day seem connected while events from weeks apart feel separate, a new study reveals the reason: Our brains physically link memories that occur close in time not in the cell bodies of neurons, but rather…

Aging compromises the lymphatic vessels surrounding the brain, disabling waste drainage from the brain and impacting cognitive function. Researchers boosted lymphatic vessel integrity in old mice and found improvements in their memory compared with old…
