(43) During acute experiments conducted 2–4 h after implanting microdialysis probes, both DEX and XJB diminished the loss in amplitude of evoked dopamine (DA) responses measured by fast-scan cyclic voltammetry (FSCV). Retrograde microdialysis was used to stimulate or inhibit the activity of the locus coeruleus for a restricted period of time, and the response of extracellular noradrenaline and dopamine in the ipsilateral and contralateral medial prefrontal cortex was recorded with microdialysis probes.

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.

Microdialysis dopamine

For in vivo monitoring of dopamine and serotonin levels, the technique of microdialysis coupled with HPLC-ECD is widely used. However, levels of dopamine and serotonin in microdialysate can widely vary, and sometimes the level can be as low as the nM level. In studies, especially on mice, researchers use small active membrane lengths which results Typical microdialysis probes, those in widespread use, have diameters of at least 250 μm. (23, 35-37) Implanting these into the brain causes tissue damage, which in turn triggers a wound response. (38-50) The wound response involves a cascade of events, some of which begin right away and some of which develop over the course of several days.

Microdialysis dopamine

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.

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. Two quantitative microdialysis methods were used to determine the concentration of extracellular dopamine in the anterior striatum of the rat. The microdialysis probe recoveries for dopamine, serotonin, methamphetamine, amphetamine, 4-hydroxymethamphetamine and 4-hydroxyamphetamine were tested in vitro.

Although microdialysis is widely used to sample endogenous and exogenous substances in vivo, interpretation of the results obtained by this technique remains controversial. The goal of the present study was to examine recent criticism of microdialysis in the specific case of dopamine (DA) measurements in the brain extracellular microenvironment. The apparent steady‐state basal extracellular

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. Previous reports, however, suggest that the tissue response to implantation of devices may affect the outcome of the measurements. tomography (SPECT). In this study, we validated the measure of amphetamine-induced dopamine release with SPECT in nonhuman primates.

Pretreatment with alpha MPT significantly reduced the effect of amphetamine on [123I]IBZM binding to D2 receptors, confirming that this effect was mediated by
