ACS Chemical Neuroscience, 10(3), 1497–1505.

By: M. Spanos n, X. Xie n, J. Gras-Najjar n, S. White n & L. Sombers n

author keywords: Glutamate; acetylcholine; dopamine; sensory stimuli; ventral tegmental area
MeSH headings : Animals; Cell Body / drug effects; Cell Body / metabolism; Cholinergic Agonists / administration & dosage; Dopamine / metabolism; Male; Microinjections / methods; N-Methylaspartate / administration & dosage; Photic Stimulation / methods; Psychomotor Performance / drug effects; Psychomotor Performance / physiology; Rats; Rats, Sprague-Dawley; Receptors, N-Methyl-D-Aspartate / agonists; Receptors, N-Methyl-D-Aspartate / antagonists & inhibitors; Receptors, N-Methyl-D-Aspartate / metabolism; Ventral Tegmental Area / drug effects; Ventral Tegmental Area / metabolism
TL;DR: It is suggested that acetylcholine and glutamate synergistically act at dopamine cells in the VTA to modulate VTA-NAc shell dopaminergic output, and this underlies motivation to lever press for a motivationally neutral visual stimulus. (via Semantic Scholar)

Quantitation of Hydrogen Peroxide Fluctuations and Their Modulation of Dopamine Dynamics in the Rat Dorsal Striatum Using Fast-Scan Cyclic Voltammetry


By: M. Spanos n, J. Gras-Najjar n, J. Letchworth n, A. Sanford n, J. Toups n & L. Sombers n

author keywords: oxidative stress; reactive oxygen species; H2O2; FSCV; Parkinson's disease; basal dopamine concentrations
MeSH headings : Animals; Dopamine / metabolism; Electric Stimulation; Electrochemical Techniques; Hydrogen Peroxide / metabolism; Male; Neostriatum / drug effects; Neostriatum / metabolism; Oxidative Stress; Rats; Rats, Sprague-Dawley; Reactive Oxygen Species / metabolism; Rotenone / pharmacology; Uncoupling Agents / pharmacology
TL;DR: Increases in endogenous H2O2 in the dorsal striatum attenuated electrically evoked DA release, and also decreased basal DA levels in this brain region will help to disambiguate the chemical mechanisms underlying the progression of neurodegenerative disease states, such as Parkinson's disease, that involve oxidative stress.
