Serotonin 5-HT2A receptors in the CA1 field of the hippocampus mediate head movements in the rabbit.
Kuldip D Dave et al.
Psychopharmacology, 176(3-4), 287-295 (2004-04-27)
Motor movements (head bobs) in the rabbit have been shown to be elicited by LSD-like hallucinogenic drugs through actions at central serotonin 5-HT(2A) receptors, though their central locus remains unknown. Serotonergic innervation of the hippocampus has been suggested to play
John A Harvey et al.
Psychopharmacology, 172(4), 435-442 (2003-12-20)
Associative learning during classical trace eyeblink conditioning has been shown to be regulated by serotonin 5-HT(2A )receptors and to be critically dependent on the integrity of frontal cortex. Chronic administration of 5-HT(2A) ligands has been shown to produce a selective
S E Welsh et al.
Psychopharmacology, 137(2), 157-163 (1998-06-18)
The 5-HT(2A/2C) receptor antagonist, ritanserin, was reported to retard the acquisition of conditioned responses (CRs) during classical conditioning of the rabbit's nictitating membrane (NM) response. The present study compared the effects of ritanserin on acquisition of CRs to a tone
C R Ashby et al.
Synapse (New York, N.Y.), 10(1), 7-15 (1992-01-11)
In the present study, we investigated the effects of various serotonin (5-HT) antagonists on 5-HT's action on medial prefrontal cortical cells (mPFc) using the techniques of single cell recording and microiontophoresis. The microiontophoretic application of 5-HT (10-80 nA) produced a
A G Romano et al.
Psychopharmacology, 184(2), 173-181 (2005-12-22)
Associative learning during Pavlovian eyeblink conditioning has been shown to be regulated by 5-HT2A receptors. The existence of inverse agonists that retard learning through an action at the 5-HT2A receptor suggests the existence of constitutive activity at that receptor and
