Abstract

We recently found that intracortical injection of the selective and competitive N‐methyl‐d‐aspartate (NMDA) receptor antagonist 3‐(R)‐2‐carboxypiperazin‐4‐propyl‐1‐phosphonic acid (CPP) impaired attentional performance in rats and blockade of 5‐hydroxytryptamine (5‐HT)2A receptors antagonized this effect. Here, we used the microdialysis technique in conscious rats to study the effect of CPP on extracellular glutamate (GLU) in the medial prefrontal cortex (mPFC) and the regulation of this effect by 5‐HT 2A receptors. Intraperitoneal injection of 20 mg/kg CPP increased extracellular GLU in the mPFC (201% of basal levels) but had no effect on 5‐HT. Intracortical infusion of 100 µ m CPP increased extracellular GLU (230% of basal values) and 5‐HT (150% of basal values) in the mPFC, whereas 30 µ m had no significant effect. The effect of 100 µ m CPP on extracellular GLU was abolished by tetrodotoxin, suggesting that neuronal activity is required. Subcutaneous injection of 40 µg/kg M100,907 completely antagonized the effect of 100 µ m cpp on extracellular GLU, whereas 10 µg/kg caused only partial attenuation. Likewise, intracortical infusion of 0.1 µ m M100,907 completely reversed the increase of extracellular GLU induced by CPP. These findings show that blockade of NMDA receptors in the mPFC is sufficient to increase extracellular GLU locally. The increase of cortical extracellular GLU may contribute to CPP‐induced cognitive deficits and blockade of 5‐HT 2A receptors may provide a molecular mechanism for reversing these deficits caused by dysfunctional glutamatergic transmission in the mPFC.

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.
