Normal rats trained to circle show asymmetric caudate dopamine release
TLDR
Monitoring of catecholamine release in male Sprague-Dawley rats trained to circle for sucrose/water reward provided evidence that dopamine is released asymmetrically from caudate in unlesioned rats during voluntary behavior.About:

The acute effects of methylenedioxymethamphetamine on dopamine release in the awake-behaving rat
TL;DR: This study provides the first evidence that MDMA induces dopamine release in vivo and that this effect is region, time- and dose-dependent.

Regional brain dopamine metabolism: a marker for the speed, direction, and posture of moving animals.
Curt R. Freed,Bryan K. Yamamoto +1 more
TL;DR: Dopamine metabolism in the nucleus accumbens was more strongly linked to the speed and direction of movement, while in the caudate nucleus dopamine and 3,4-dihydroxyphenylacetic acid were affected most by posture and direction.

Chemically modified electrode for in vivo monitoring of brain catecholamines
Charles D. Blaha,Ross F. Lane +1 more
TL;DR: The electrodes developed allow catecholamines to be electrochemically distinguished from ascorbic acid and the dopamine metabolite 3,4-dihydroxyphenylacetic acid and exhibits long-term response stability in brain tissue.

Electrocoating carbon fiber microelectrodes with Nafion improves selectivity for electroactive neurotransmitters
Michael. Brazell,Richard Kasser,Kenneth J. Renner,Jian Xing Feng,B. Moghaddam,Ralph N. Adams +5 more
TL;DR: A method which improves carbon fiber microelectrode selectivity for cationic amines by electrocoating the fiber with a thin film of the ionic polymer, Nafion, is described.

[Distribution of noradrenaline and dopamine (3-hydroxytyramine) in the human brain and their behavior in diseases of the extrapyramidal system].
H. Ehringer,Oleh Hornykiewicz +1 more
TL;DR: The distribution of noradrenaline and dopamine in human adult and newborn brains has been investigated in this paper, where the greatest amounts of dopamine were found in the hypothalamus, the central gray matter of the mesencephalon, the reticular formation and in the area postrema.

In vivo electrochemical detection of catechols in the neostriatum of anaesthetized rats: dopamine or DOPAC?
TL;DR: The DPV method used in conjunction with an electrochemical treatment of this electrode yields stable and reproducible peaks in which catecholamines and AA are resolved from each other, suggesting that the technique may be a useful means of following dopaminergic activity in vivo.
