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 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 ...

Small and seemingly specialized, the brain's locus coeruleus (LC) region has been stereotyped for its outsized export of the arousal-stimulating neuromodulator norepinephrine. In a new paper and with ...

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 ...

Researchers have found that one key role of the neuromodulator noradrenaline, produced by the locus coeruleus, is to help the brain learn from surprising outcomes. When your brain needs you to pay ...

Tsukuba, Japan—Mild exercise results in a feeling of mental clarity and enhances cognition and memory. A possible mechanism behind such effects is the activation of the arousal center in the brainstem ...

Engaging the brain’s plasticity by stimulating the locus coeruleus, a region in the brainstem, could be a clinically relevant approach to optimize the efficacy of cochlear implants in restoring ...
