Abstract

We studied the role of 5‐HT 1A receptors in controlling the release of glutamate (GLU) in the medial prefrontal cortex (mPFC) of conscious rats with the in vivo microdialysis technique. The effect of the 5‐HT 1A receptor agonist 8‐hydroxy‐2‐(di‐n‐propylamino)tetralin infused in the prefrontal cortex was examined under basal conditions and on the rise of extracellular GLU (+106%) induced by co‐infusion of the competitive N‐methyl‐d‐aspartate receptor antagonist 3‐[(R)‐2‐carboxypiperazin‐4yl]‐propyl‐1‐phosphonic acid (CPP). 8‐OH‐DPAT (0.3 and 3 μ m) had no effect on basal extracellular GLU, but the higher concentration completely abolished the rise of extracellular GLU induced by CPP. CPP also increased extracellular serotonin (5‐HT) in the mPFC (+50%) and this effect was antagonized by 3 μ m 8‐OH‐DPAT which, by itself, had no effect on basal 5‐HT release. The effects of 8‐OH‐DPAT on extracellular GLU and 5‐HT were reversed by the 5‐HT 1A receptor antagonist WAY100 635 (100 μ m), indicating a selective involvement of 5‐HT 1A receptors. WAY100 635 had no effect by itself. These results show that the stimulation of cortical 5‐HT 1A receptors prevents the CPP‐evoked rise of extracellular GLU and 5‐HT and suggest that these effects may contribute to the ability of intracortical 8‐OH‐DPAT to counteract cognitive deficits caused by the blockade of NMDA receptors.

  • 5-HT1A antagonism with 8-OH-DPAT within the PFC blocks CPP-induced elevations in extracellular glutamate.

    “5-HT1A antagonism with 8-OH-DPAT within the PFC was also able to block CPP-induced elevations in extracellular glutamate (Calcagno et al 2006).”

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.
