The locus coeruleus is a region of the brain that is instrumental in coordinating our mental processing and is the primary source of noradrenaline in the brain, which acts to regulate arousal states ...

Researchers at the University of Lausanne have identified a novel role for the brain's 'locus coeruleus' in sleep and its disruptions. This brain region facilitates the transition between NREM and REM ...

Most people think of Alzheimer’s disease as an illness of aging. But in fact, the brain changes that characterize it begin ...

A restful night alternates in cycles between non-rapid eye movement (NREM) and rapid eye movement (REM) sleep states. The study from UNIL shows that a brain region called the "locus coeruleus" (in ...

Studies suggest that starting in middle age, nerve cells in the locus coeruleus may get damaged by tau buildup, and that ...

Deep sleep does far more than rest the body — it activates a powerful brain-driven system that controls growth hormone, fueling muscle and bone strength, metabolism, and even mental performance.

Turns out, your brain isn’t just a squishy mass of pinkish-grey. Hidden deep inside is a tiny “blue spot” that plays a major role in our cognition — and a new study shows that it goes through a ...

Scientists have known for some time that people who experience early childhood adversity are more prone to developing health and behavioral issues in adulthood, but the brain mechanisms behind these ...

Many people believe that Alzheimer’s disease only begins in old age. However, scientists now know that the changes linked to ...

Deep sleep does more than help you feel rested. Research shows it triggers growth hormone release, supporting muscle repair, ...
