Microdialysis studies in the rat have consistently shown that most drugs of abuse increase extracellular dopamine levels preferentially in the shell subregion of the nucleus accumbens. The study of the relative roles of NAc subregions may considerably help our understanding of the neurobiological basis of drug addiction.

Abstract: The present study compared two different in vivo microdialysis methods which estimate the extracellular concentration of analytes at a steady state where there is no effect of probe sampling efficiency. Each method was used to estimate the basal extracellular concentration of dopamine (DA) in the nucleus accumbens of the rat.

In the present study, the in vivo microdialysis technique was used to directly manipulate extracellular dopamine concentrations in the nucleus accumbens (NAC) Avhandling: Taurine and dopamine-related effects of ethanol. By means of in vivo microdialysis we show that rats consuming high levels of ethanol respond C. Michael -- Rapid dopamine release in freely moving rats / Donita L. Robinson of dopamine near microdialysis probes / Hua Yang and Adrian C. Michael. Functional correlates of dopamine neurotransmission.

The microdialysis probe recoveries for dopamine, serotonin, methamphetamine, amphetamine, 4-hydroxymethamphetamine and 4-hydroxyamphetamine were tested in vitro. The microdialysis probes attached to the two-flow microdialysis system were incubated in well-stirred Ringer's solution bath containing 10 or 100 ng/mL of the six compounds at 37 °C. Dopamine is a catecholamine neurotransmitter that degrades rapidly in aqueous solutions; hence, its analysis following brain microdialysis is challenging. Abstract Measuring extracellular dopamine in the brain of living animals by means of microdialysis and/or voltammetry is a route towards understanding both normal brain function and pathology.

between reduction of D2 receptor binding measured with SPECT and peak dopamine release measured with microdialysis after various doses of amphetamine. Pretreatment with alpha MPT significantly reduced the effect of amphetamine on [123I]IBZM binding to D2 receptors, confirming that this effect was mediated by

Two quantitative microdialysis methods were used to determine the concentration of extracellular dopamine in the anterior striatum of the rat.

Melendez RI (1), Rodd-Henricks ZA, Engleman EA, Li TK, McBride WJ, Murphy JM. Microdialysis is commonly used in neuroscience to obtain information about the concentration of substances, including neurotransmitters such as dopamine (DA), in the extracellular space (ECS) of the brain. Microdialysis studies in the rat have consistently shown that most drugs of abuse increase extracellular dopamine levels preferentially in the shell subregion of the nucleus accumbens. The study of the relative roles of NAc subregions may considerably help our understanding of the neurobiological basis of drug addiction.
