5-HT1A receptor agonists enhance pyramidal cell firing in prefrontal cortex through a preferential action on GABA interneurons.


5-HT(1A) receptors (5-HT1AR) are expressed by pyramidal and γ-aminobutyric acidergic (GABAergic) neurons in medial prefrontal cortex (mPFC). Endogenous serotonin inhibits mPFC pyramidal neurons via 5-HT1AR while 5-HT1AR agonists, given systemically, paradoxically excite ventral tegmental area-projecting pyramidal neurons. This enhances mesocortical dopamine… (More)
