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 ...

Signal Transduction and Targeted Therapy, 2021 The phenylalanine–tyrosine–dopa–dopamine pathway provides dopamine to the brain. In this process, tyrosine hydroxylase (TH) is the rate-limiting enzyme that hydroxylates tyrosine and generates levodopa (l-dopa) with tetrahydrobiopterin (BH4) as a ...

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 ...

Dopamine and glutamate in schizophrenia: biology, symptoms and treatment
World Psychiatry, 2020 Glutamate and dopamine systems play distinct roles in terms of neuronal signalling, yet both have been proposed to contribute significantly to the pathophysiology of schizophrenia.

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 ...

Electrochemical Biosensing of Dopamine Neurotransmitter: A Review
Biosensors, 2021 Neurotransmitters are biochemical molecules that transmit a signal from a neuron across the synapse to a target cell, thus being essential to the function of the central and peripheral nervous system.

Loss of angiotensin II receptor expression in dopamine neurons in Parkinson’s disease correlates with pathological progression and is accompanied by increases in Nox4- and 8-OH guanosine-related nucleic acid oxidation and caspase-3 activation [PDF]
, 2015 In rodent models of Parkinsons disease (PD), dopamine neuron loss is accompanied by increased expression of angiotensin II (AngII), its type 1 receptor (AT1), and NADPH oxidase (Nox) in the nigral dopamine neurons and microglia.
