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

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 ...

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

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 ...

A tiny region in the brain works like a reset button that separates memory of one meaningful event from the next. Without this reset mechanism, moments could blur together and lead to the kinds of ...

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 ...

Life may unfold as a continuous stream, but our memories tell a different story. We do not recall the past as one long, unbroken text. Instead, we remember it as a series of meaningful events, like ...

We found that the locus coeruleus may provide the critical 'start' signal to the hippocampus, as if saying, 'Hey, we're in a new event now,'" said Davachi. "Prior work had shown that bursts of locus ...

Place a finger on the back of your skull, at a point roughly level with the tops of your ears. Here, deep beneath the hair, skin and bone, near a fluid-filled cavity in the root of your brain, lies a ...

The locus coeruleus is among the first brain regions to degenerate in Alzheimer's and Parkinson's disease, physicians and scientists have known. But why this area is so vulnerable is less understood.
