Less locus coeruleus degeneration and its enhanced influence on neural circuit in Parkinson's tremor

Neurobiology of Disease
Objectives: The involvement of the locus coeruleus in Parkinson's tremor remains unclear. We aimed to decode the role of locus coeruleus in Parkinson's tremor. Methods: We used MRI to examine 120 Parkinson's disease, including 48 tremor-dominant (TD) and

Utility of Fear Severity and Individual Resilience Scoring as a Surge Capacity, Triage Management Tool during Large-Scale, Bio-event Disasters [PDF]

, 2006
Threats of bioterrorism and emerging infectious disease pandemics may result in fear related consequences. Fear based signs and symptoms, if left undetected and untreated, may be extremely debilitating and lead to chronic problems with risk of permanent ...

Lower novelty-related locus coeruleus function is associated with Aβ-related cognitive decline in clinically healthy individuals

Nature Communications, 2022
Older individuals exhibiting diminished function of the locus coeruleus while learning new information show faster cognitive decline that is typical for Alzheimer’s disease.

Afferent connections of the valvula cerebelli in two teleosts, the common goldfish and the green sunfish [PDF]

, 1989
The afferent connections of the valvula cerebelli were examined in one cypriniform teleost (Carassius auratus) and one perciform teleost (Lepomis cyanellus) with the use of horseradish peroxidase as a retrograde tracer.

Possible multiple evolution of indirect telencephalo-cerebellar pathways in teleosts: studies in Carassius auratus and Pantodon buchholzi [PDF]

, 1993
Among vertebrates, telencephalo-pontine systems exist only in birds and mammals. However, three nuclei in the diencephalon and mesencephalon of teleost fishes have been indicated — analogous to the pons — to represent relay stations between telencephalon

Locus coeruleus features are linked to vagus nerve stimulation response in drug-resistant epilepsy

Frontiers in Neuroscience
The locus coeruleus–norepinephrine system is thought to be involved in the clinical effects of vagus nerve stimulation. This system is known to prevent seizure development and induce long-term plastic changes, particularly with the release of ...

Decreased Interleukin-4 Release from the Neurons of the Locus Coeruleus in Response to Immobilization Stress [PDF]

, 2016
It has been demonstrated that immobilization (IMO) stress affects neuroimmune systems followed by alterations of physiology and behavior. Interleukin-4 (IL-4), an anti-inflammatory cytokine, is known to regulate inflammation caused by immune challenge ...

Effects of Noninvasive Cervical Vagal Nerve Stimulation on Cognitive Performance But Not Brain Activation in Healthy Adults

Neuromodulation: Technology at the Neural Interface, EarlyView., 2020
Abstract Objectives While preliminary evidence suggests that noninvasive vagal nerve stimulation (nVNS) may enhance cognition, to our knowledge, no study has directly assessed the effects of nVNS on brain function and cognitive performance in healthy individuals.

The Contribution of the Locus Coeruleus–Noradrenaline System Degeneration during the Progression of Alzheimer’s Disease

Biology, 2022
Alzheimer’s disease (AD), which is characterized by extracellular accumulation of amyloid-beta peptide and intracellular aggregation of hyperphosphorylated tau, is the most common form of dementia.

The effects of exogenous melatonin on morphological changes in locus ceruleus nucleus Characterized by REM sleep deprivation

Otorhinolaryngology and Facial Plastic Surgery, 2017
Background: Neurodegeneration in the locus coeruleus (LC) has been documented in several central nervous system (CNS) neurodegenerative diseases and sleep deprivation.
