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. Such addictions can also be defined in terms of the brain mechanisms they activate; most addictive drugs cause elevations in extracellular levels of the ...

KLHL12 promotes non-lysine ubiquitination of the dopamine receptors D-4.2 and D-4.4, but not of the ADHD-associated D-4.7 variant [PDF]
, 2015 Dopamine D-4 Receptor Polymorphism : The dopamine D-4 receptor has an important polymorphism in its third intracellular loop that is intensively studied and has been associated with several abnormal conditions, among others, attention deficit ...

Conformation of dopamine at the dopamine receptor. [PDF]
Proceedings of the National Academy of Sciences, 1978 Tritiated dopamine was used to label the dopamine receptor in membranes isolated from the rat corpus striatum. Scatchard analysis of displacement of [3H]dopamine by nonradioactive dopamine indicated the presence of two binding sites. The similarities in affinity, capacity, and drug specificity of the high-affinity site in the striatal membranes from ...

Electrochemical Aptasensor for Detection of Dopamine [PDF]
, 2020 This work presents a proof of concept of a novel, simple, and sensitive method of detection of dopamine, a neurotransmitter within the human brain. We propose a simple electrochemical method for the detection of dopamine using a dopamine-specific aptamer

Aversive Stimuli Drive Drug Seeking in a State of Low Dopamine Tone [PDF]
, 2015 Background Stressors negatively impact emotional state and drive drug seeking, in part, by modulating the activity of the mesolimbic dopamine system.

Cigarette Use and Striatal Dopamine D2/3 Receptors: Possible Role in the Link between Smoking and Nicotine Dependence. [PDF]
, 2016 BackgroundCigarette smoking induces dopamine release in the striatum, and smoking- or nicotine-induced ventral striatal dopamine release is correlated with nicotine dependence.

Corticosterone Regulates Both Naturally Occurring and Cocaine‐Induced Dopamine Signaling by Selectively Decreasing Dopamine Uptake [PDF]
, 2017 Stressful and aversive events promote maladaptive reward‐seeking behaviors such as drug addiction by acting, in part, on the mesolimbic dopamine system. Using animal models, data from our laboratory and others show that stress and cocaine can interact to

Cholinergic modulation of dopamine overflow in the rat neostriatum: A fast cyclic voltammetric study in vitro [PDF]
, 1994 Stimulus-evoked dopamine overflow in rat neostriatal slices was determined using fast cyclic voltammetry. The dopamine efflux induced by intrastriatal stimulation increased with stimulus intensity and was found to be enhanced by more than 100% upon ...

Dopamine Release Dynamics in the Tuberoinfundibular Dopamine System [PDF]
The Journal of Neuroscience, 2019 The relationship between neuronal impulse activity and neurotransmitter release remains elusive. This issue is especially poorly understood in the neuroendocrine system, with its particular demands on periodically voluminous release of neurohormones at the interface of axon terminals and vasculature.

BMJ, 1997 Renal failure often manifests as oliguria. Many therefore view oliguria as a sinister development that should be prevented or treated in the hope of avoiding renal failure. However, oliguria can be a normal physiological response and, in itself, is a poor predictor of acute renal failure.1 2 Nevertheless, dopamine infusions have gained popularity over ...
