Elevated Norepinephrine may be a Unifying Etiological Factor in the Abuse of a Broad Range of Substances: Alcohol, Nicotine, Marijuana, Heroin, Cocaine, and Caffeine

open access: yesSubstance Abuse: Research and Treatment, 2013
A wide range of commonly abused drugs have effects on the noradrenergic neurotransmitter system, including alterations during acute intoxication and chronic use of these drugs.

Dopaminergic novelty detection and theta oscillations: Virtual reality‐based adaptive interventions for cognitive enhancement in aging

open access: yesIbrain, EarlyView.
Aging‐related cognitive decline is associated with reduced dopaminergic signaling and disrupted theta oscillations, which together impair novelty detection and memory formation. This review shows how VR environments can be used to deliver adaptive, novelty‐rich stimuli that engage dopaminergic circuits and entrain theta rhythms, thereby enhancing ...

Opiates control ACTH through a noradrenergic mechanism.

open access: yes, 1982
The administration of 16 mg of naloxone to six normal male subjects produced a significant rise in plasma cortisol. Pre-treatment with the noradrenergic α1-antagonist, thymoxamine 0.2 mg/kg, blocked this rise.

Acute Modafinil Exposure Induces Neurobehavioral Alterations in Zebrafish: Implications for Off‐Label Cognitive Enhancement

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Modafinil (2‐(benzhydrylsulfinyl)acetamide) is a psychostimulant commonly prescribed for sleep disorders such as narcolepsy, excessive daytime sleepiness, and obstructive sleep apnea. Recently, its use has extended beyond clinical indications, with neurotypical individuals adopting it as a smart drug to enhance alertness and cognitive ...

Noradrenergic and non-noradrenergic nerves containing small granular vesicles in Auerbach's plexus of the guinea-pig:evidence against the presence of noradrenergic synapses

open access: yes, 1982
The appearance and distribution of varicosities containing small granular vesicles in Auerbach's plexus of the guinea-pig ileum, distal colon and rectum has been studied with the electron-microscope. Two types of varicosity were recognised.

Noradrenergic and Cholinergic Reinnervation of Islet Grafts in Diabetic Rats [PDF]

open access: yes, 1996
Grafted islets become denervated due to the islet transplantation procedure. The aim of the present study was 1) to examine whether islet grafts in the liver, the spleen, and under the kidney capsule in rats become reinnervated following the ...

Subthalamic Nucleus Deep Brain Stimulation Improves Kinetic Tremor in Parkinson's Disease

open access: yesMovement Disorders Clinical Practice, EarlyView.
Abstract Background Although resting tremor is a characteristic feature of Parkinson's disease (PD), many patients also suffer from action tremor. Deep brain stimulation (DBS) of the subthalamic nucleus (STN) is effective in reducing motor symptoms. However, it is unclear to what extent STN‐DBS improves action tremor in PD, particularly kinetic tremor.

Cardiac MIBG Scintigraphy in Neurodegenerative Parkinsonism: Limitations in Clinical Practice

open access: yesMovement Disorders Clinical Practice, EarlyView.
Abstract Background Reduced cardiac uptake on 123Iodine‐metaiodobenzylguanidine (MIBG) scintigraphy is a valuable tool for differentiating neurodegenerative parkinsonism but interpretation can be difficult due to comorbidities and drug‐tracer interactions.

Noradrenergic Fiber Sprouting in the Cerebellum

open access: yes, 1982
In order to attain a better understanding of the sprouting response of noradrenergic fibers in the central nervous system (CNS), noradrenergic innervation to the cerebellum was observed by the glyoxylic acid method after a variety of manipulations and in

Tracking Genetic Parkinson's Disease with Molecular Imaging: A Systematic Review

open access: yesMovement Disorders Clinical Practice, EarlyView.
Abstract Background Parkinson's disease (PD) is a worldwide, complex neurodegenerative disorder influenced by both genetic and environmental factors. Around 15–20% of PD cases are linked to genetic mutations, providing insights into the disease's pathogenesis.
