A new study has linked signs of heightened arousal and reactivity -- a core symptom of posttraumatic stress disorder (PTSD) -- to overactivity of the locus coeruleus (LC), a brain region that mediates ...

The locus coeruleus is a nucleus in the pons that plays important roles in homeostasis, arousal and sleep, memory and emotions. Neurons of the locus coeruleus project to numerous brain areas including ...

The locus coeruleus (LC) — a tiny, ancient brainstem structure that regulates arousal, attention and memory—plays a far more ...

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 ...

Neural activity in the noradrenergic locus coeruleus correlates with periods of wakefulness and arousal. However, it is unclear whether tonic or phasic activity in these neurons is necessary or ...

Tau aggregation begins not in the cortex, but in the brainstem. Does tangle deposition in the locus coeruleus, which often starts in a person’s 30s, presage Alzheimer’s disease? In the September 22 ...

Researchers tested patients with MS and controls for the presence of certain metals in the locus ceruleus, including iron, lead, silver, and mercury, among others. Overall, MS patients had higher ...

This is a preview. Log in through your library . Abstract Electrotonic coupling synchronizes the spontaneous firing of locus ceruleus (LC) neurons in the neonatal rat brain, whereas in adults, ...

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 ...

This Webinar recapped the latest research in this area. Michael Heneka of the University of Bonn, Germany, and Doug Feinstein of the University of Illinois, Chicago, gave presentations, and were ...

The prevailing theory of panic disorder states that there are two types of panic attacks, non-phobic spontaneous panic and triggered panic attacks. Nonphobic panic attacks are thought to be the result ...
