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.

Cheng et al. reported that in vitro microdialysis combined with HPLC is a rapid, simple, and sensitive method for measurement of DOPAC, HVA, serotonin, and 5-hydroxyindolacetic acid in human plasma . The Coolidge effect describes the reinitiation of sexual behavior in a “sexually satiated” animal in response to a novel receptive mate. Given the role of the mesolimbic dopamine (DA) system in the initiation and maintenance of motivated behavior, microdialysis was used to monitor nucleus accumbens (NAC) DA transmission during copulation, sexual satiety, and the reinitiation of sexual Decreased striatal dopamine release induced by interferon (IFN)-alpha was reversed by levodopa (L-DOPA). IFN-alpha (20 MIU/m 2 subcutaneously) was administered to 4 rhesus monkeys for 4 weeks, and reverse in vivo microdialysis sampling with amphetamine (AMPH; 100 μM) stimulation was conducted in the presence or absence of the dopamine precursor, L-DOPA (10 μM administered by reverse in vivo the VTA, caused an increase of extracellular dopamine to -125% of controls in the ipsilateral nucleus accumbens (Fig.

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.

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.

Effect of muscimol and bicuculline, infused into the VTA, on the dialysate content of dopamine in the ipsilateral nucleus accumbens The GABA, agonist muscimol was infused via the microdialysis The tonic influence of dopamine D1 and D2receptors on the activity of striatal neurons in vivo was investigated by performing intracellular recordings concurrently with reverse microdialysis in chloral hydrate-anesthetized rats. Striatal neurons were recorded in the vicinity of the microdialysis probe to assess their activity during infusions of artificial CSF (aCSF), the D1 receptor in viva Microdialysis in Freely Moving Rats.

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

(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.

Pallidal dopamine, GABA and the endogenous opioid peptides enkephalins have independently been shown to be important controllers of sensorimotor processes. Using in vivo microdialysis coupled to liquid chromatography–mass spectrometry and a behavioral assay, we explored the interaction between these three neurotransmitters in the rat globus pallidus.
