Evoked Extracellular Dopamine In Vivo in the Medial Prefrontal Cortex
Abstract
Abstract:The measurement of evoked extracellular dopamine in the medial prefrontal cortex by using fast‐scan cyclic voltammetry with carbon‐fiber microelectrodes was established and release characteristics of mesoprefrontal dopamine neurons were examined in vivo in anesthetized rats. Despite the sparse dopaminergic innervation and the presence of more dense noradrenergic and serotonergic innervations overall in the medial prefrontal cortex, the measurement of extracellular dopamine was achieved by selective recording in dopamine‐rich terminal fields and selective activation of ascending dopamine neurons. This was confirmed by electrochemical, pharmacological, and anatomical evidence. An increased release capacity for mesoprefrontal dopamine neurons was also demonstrated by the slower decay of the evoked dopamine response after inhibition of catecholamine synthesis and the maintenance of the evoked dopamine response at higher levels in the medial prefrontal cortex compared with the striatum during supraphysiological stimulation.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
