Abstract
Tonic neurochemical dopamine activity underlies many brain functions; however a consensus on this important concentration has not yet been reached. In this work, we introduce in vivo fast-scan controlled-adsorption voltammetry to report tonic dopamine concentrations (90 ± 9 nM) and the dopamine diffusion coefficient (1.05 ± 0.09 × 10(-6) cm(2) s(-1)) in the mouse brain.
摘要
张力性神经化学多巴胺活性是许多脑功能的基础；然而，关于这一重要浓度尚未达成共识。在这项工作中，我们引入体内快速扫描控制吸附伏安法来报告小鼠脑中的张力性多巴胺浓度（90±9 nM）和多巴胺扩散系数（1.05±0.09×10(-6) cm(2) s(-1)）。
