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.

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.

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.

Dopamine is electroactive, and can also be measured using carbon fiber microelectrodes coupled with voltammetry. 2019-12-02 · Dopamine (DA) is a monoamine neurotransmitter that plays a major role in motivation, learning, cognition and movement control of humans [1, 2].Concentrations of dopamine in the range between 10 nM and 1 μM are normally detected in the extracellular fluid of the central nervous system [3, 4]. In support of the role of dopamine (DA) in these actions, the results from a number of studies using in vivo microdialysis have reported an increase in extracellular levels of DA following Δ 9 ‐THC administration in various regions of the nigrostriatal and mesolimbic systems (Chen et al., 1990a, 1990b; Ng Cheong Ton et al., 1998; Tanda et al., 1997).

Microdialysis of dopamine in the nucleus accumbens of alcohol-preferring (P) rats during anticipation and operant self-administration of ethanol. 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. 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. 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.
