Abstract: The technique of microdialysis permits the assessment of neurotransmitter activity and the monitoring of other cellular entities in tissue extracellular fluid. The method is widely used for quantifying biogenic amine and amino acid transmitters, peptides, administered drugs, and other molecules in response to various experimental treatments. This article provides an overview of the manner in which the methodology of intracerebral microdialysis is utilized in the field of neurotoxicology to elucidate the actions of environmental agents. The technique is employed in a variety of creative ways to address specific experimental goals involving myriad toxicants. With appropriate consideration of method parameters, investigators have also been able to address mechanistic issues in their studies. These investigations consist of sampling of neurotransmitters in extracellular fluid after various protocols of environmental metal exposure as well as assessments of blood-brain barrier permeability, the detection of reactive oxygen species, and description of the toxicodynamics of environmental agents. The purpose of this examination is not to review the investigational findings, per se, but to highlight the various approaches utilized with this methodology and the experimental questions that have been addressed. © 2019 by John Wiley & Sons, Inc.
