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 ...

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 ...

A small cluster of cells deep within our brains, called the locus coeruleus, affects how awake and attentive we are, how we respond to stress, how we cope with anxiety and fear, and how we create ...

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 ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

The Nature Index 2024 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

During sleep, the brain produces growth hormone to help build muscle and bone and reduce fat. UC Berkeley research in mice reveals the brain circuits that regulate growth hormone release, along with a ...

New findings published in the journal Neuron suggest that the locus coeruleus—a tiny region buried deep in the brainstem—may play a key role in helping the brain separate one memory from the next.

Deep within the brainstem is a structure no bigger than a grain of rice, the locus coeruleus. The LC is often referred to as the “blue spot” because of a distinct blue pigment produced from its inner ...
