Noradrenergic control of gene expression and long-term neuronal adaptation evoked by learned vocalizations in songbirds. [PDF]

open access: yesPLoS ONE, 2012
Norepinephrine (NE) is thought to play important roles in the consolidation and retrieval of long-term memories, but its role in the processing and memorization of complex acoustic signals used for vocal communication has yet to be determined.

Type‐Specific Single‐Neuron Analysis Reveals Mitochondrial DNA Maintenance Failure Affecting Atrophying Pontine Neurons Differentially in Lewy Body Dementia Syndromes

open access: yesAging Cell, EarlyView.
(a) Mitochondria contain wild‐type (black)/mutant (red) mtDNA; exceeding the mtDNA mutation threshold compromises OXPHOS, potentially driving degeneration of neurons vulnerable to age‐related neurodegenerative disease. Cellular compensations that is, mtDNA copy number upregulation and crosstalk with nuclear DNA may fail, driving neurodegeneration ...

Critical role of somatostatin receptor 2 in the vulnerability of the central noradrenergic system: new aspects on Alzheimer's disease [PDF]

open access: yes, 2015
Alzheimer's disease and other age-related neurodegenerative disorders are associated with deterioration of the noradrenergic locus coeruleus (LC), a probable trigger for mood and memory dysfunction.

Effect of anticholinergic eye drops on intraorbital, periorbital and brain pulsation power

open access: yesActa Ophthalmologica, EarlyView.
Abstract Purpose The study aims to investigate the effect of pharmacologically reducing parasympathetic activity on ocular and cerebral pulsations, inspired by recent discoveries of a glymphatic‐like system in the eye driven by physiological pulsations.

Differences in peripheral noradrenergic function among actively drinking and abstinent alcohol-dependent individuals. [PDF]

open access: yes, 2004
We examined whether excessive alcohol consumption was related to changes in plasma levels of noradrenaline (NA) and whether these changes recover following abstinence.

Parkinson's disease dementia: a neural networks perspective. [PDF]

open access: yes, 2015
In the long-term, with progression of the illness, Parkinson's disease dementia affects up to 90% of patients with Parkinson's disease. With increasing life expectancy in western countries, Parkinson's disease dementia is set to become even more ...

The Influence of Resiniferatoxin (RTX) and Tetrodotoxin (TTX) on the Distribution, Relative Frequency, and Chemical Coding of Noradrenergic and Cholinergic Nerve Fibers Supplying the Porcine Urinary Bladder Wall

open access: yesToxins, 2017
The present study investigated the influence of intravesically instilled resiniferatoxin (RTX) or tetrodotoxin (TTX) on the distribution, number, and chemical coding of noradrenergic and cholinergic nerve fibers (NF) supplying the urinary bladder in ...

Stereological analysis of cholinergic neurons within bilateral pedunculopontine nuclei in health and when affected by Parkinson's disease

open access: yesBrain Pathology, EarlyView.
(A) PPN‐cholinergic neurons degenerate during PD. We stereologically counted their rostro‐caudal distribution in post‐mortem PPNs in health versus PD. (Bi) Serial PPN‐containing samples were cholinergic antibody‐DAB stained. (Bii) Only DAB‐stained neurons on green lines and inside the box were counted.

Central mechanisms mediating the hypophagic effects of oleoylethanolamide and N-acylphosphatidylethanolamines: different lipid signals? [PDF]

open access: yes, 2015
The spread of "obesity epidemic" and the poor efficacy of many anti-obesity therapies in the long-term highlight the need to develop novel efficacious therapy. This necessity stimulates a large research effort to find novel mechanisms controlling feeding

Preclinical models for evaluating psychedelics in the treatment of major depressive disorder

open access: yesBritish Journal of Pharmacology, EarlyView.
Psychedelic drugs have seen a resurgence in interest as a next generation of psychiatric medicines with potential as rapid‐acting antidepressants (RAADs). Despite promising early clinical trials, the mechanisms which underlie the effects of psychedelics are poorly understood.
