Measurement of Dopamine Using Fast Scan Cyclic Voltammetry in Rodent Brain Slices.

Fast scan cyclic voltammetry (FSCV) is an electrochemical technique that allows sub-second detection of oxidizable chemical species, including monoamine neurotransmitters such as dopamine, norepinephrine, and serotonin. This technique has been used to record the physiological dynamics of these neurotransmitters in brain tissue, including their rates of release and reuptake as well as the activity of neuromodulators that regulate such processes. This protocol will focus on the use of FSCV for the detection of dopamine within the nucleus accumbens in slices obtained from rodents. We have included all necessary materials, reagents, recipes, procedures, and analyses in order to successfully perform this technique in the laboratory setting. Additionally, we have also included cautionary points that we believe will be helpful for those who are novices in the field.
