Dopamine modulation of avoidance behavior in Caenorhabditis elegans requires the NMDA receptor NMR-1. [PDF]

PLoS ONE, 2014
The nematode C. elegans utilizes a relatively simple neural circuit to mediate avoidance responses to noxious stimuli such as the volatile odorant octanol. This avoidance behavior is modulated by dopamine.

Reduced Insulin Sensitivity Is Related to Less Endogenous Dopamine at D2/3 Receptors in the Ventral Striatum of Healthy Nonobese Humans

International Journal of Neuropsychopharmacology, 2015
Background: Food addiction is a debated topic in neuroscience. Evidence suggests diabetes is related to reduced basal dopamine levels in the nucleus accumbens, similar to persons with drug addiction.

Dopamine and Addiction.

Annual Review of Psychology, 2020
Addiction is commonly identified with habitual nonmedical self-administration of drugs. It is usually defined by characteristics of intoxication or by characteristics of withdrawal symptoms.

Multimodal Autonomic Biomarkers Predict Phenoconversion in Pure Autonomic Failure

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Pure autonomic failure (PAF) presents with autonomic failure without other neurological features. A third develop central neurological features, fulfilling criteria for multiple system atrophy (MSA) and Lewy body diseases (LBD), including Parkinson's disease and Dementia with Lewy bodies.

Chronic Pain in Parkinson’s Disease: Prevalence, Sex Differences, Regional Anatomy and Comorbidities

Annals of Clinical and Translational Neurology, EarlyView.
Chronic pain affected 66.2% of 10,631 individuals with Parkinson's disease, with higher prevalence and severity in females. Pain most often involved the buttocks, lower back, neck, and knees, and was linked to depression, sleep disorders, and osteoarthritis.

The renal dopamine receptors. [PDF]

Journal of the American Society of Nephrology, 1992
Dopamine is an endogenous catecholamine that modulates many functions including behavior, movement, nerve conduction, hormone synthesis and release, blood pressure, and ion fluxes. Dopamine receptors in the brain have been classically divided into D1 and D2 subtypes, based on pharmacological data.

Moyamoya Disease and the Risk of Parkinson's Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives Moyamoya disease (MMD) is a rare cerebrovascular disorder characterized by the progressive narrowing of arteries at the base of the brain, forming abnormal collateral vascular networks. While vascular parkinsonism is noted in MMD, its link to Parkinson's disease (PD) has not been explored.

Purkinje Cell Loss in Essential Tremor: Collective Data From 215 Brains Over a 21‐Year Period

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Essential tremor is a highly prevalent movement disorder. Pathological changes observed in essential tremor cerebella center around Purkinje cells and neighboring neuronal populations. Postmortem studies have variably, but not always, shown reduced Purkinje cell counts in essential tremor compared to controls.

Reciprocal synapses between mushroom body and dopamine neurons form a positive feedback loop required for learning

eLife, 2017
Current thought envisions dopamine neurons conveying the reinforcing effect of the unconditioned stimulus during associative learning to the axons of Drosophila mushroom body Kenyon cells for normal olfactory learning.

Dopamine Receptors in a Songbird Brain [PDF]

Journal of Comparative Neurology, 2010
AbstractDopamine is a key neuromodulatory transmitter in the brain. It acts through dopamine receptors to affect changes in neural activity, gene expression, and behavior. In songbirds, dopamine is released into the striatal song nucleus area X, and the levels depend on social contexts of undirected and directed singing.
