PSILOCYBIN, an indoleamine hallucinogen, produces a psychosis-like syndrome in humans that resembles first episodes of schizophrenia. In healthy human volunteers, the psychotomimetic effects of psilocybin were blocked dose-dependently by the serotonin-2A antagonist ketanserin or the atypical antipsychotic risperidone, but were increased by the dopamine antagonist and typical antipsychotic haloperidol. These data are consistent with animal studies and provide the first evidence in humans that… Expand
Crosstalk Between 5-HT2A and mGlu2 Receptors: Implications in Schizophrenia and Its Treatment
Recent advances in understanding of the crosstalk between these two receptors, as well as their implication in schizophrenia and antipsychotic drug action are reviewed. Expand
Psychedelics and schizophrenia
Results on the receptor, signalling and circuit mechanisms underlying the response to psychedelic and antipsychotic drugs might lead to unification of the serotonin and glutamate neurochemical hypotheses of schizophrenia. Expand
Hallucinogens and Serotonin 5-HT2A Receptor-Mediated Signaling Pathways.
Recent advances in understanding hallucinogen drug action are reviewed through characterization of structure, neuroanatomical location, and function of the 5-HT2A receptor. Expand
Serotonergic Hallucinogens and Emerging Targets for Addiction
• Converging lines of evidence from pharmacologic, electrophysiologic, and behavioral research in animals strongly suggest that activation of cortical 5-hydroxytryptamine-2A receptors is the mostExpand
Electrophysiology of 5-HT2A Receptors and Relevance for Hallucinogen and Atypical Antipsychotic Drug Actions
The electrophysiology of 5-HT2A receptors in the prefrontal cortex and their relevance for normal brain function and for hallucinogen and atypical antipsychotic drug actions are explored. Expand
Serotonin and serotonin receptors in hallucinogen action
Abstract Hallucinogens (psychedelics) are substances that induce profound changes in perception and cognition. The closely related 3,4-methylenedioxymethamphetamine (MDMA) produces euphoria and aExpand
Animal Models and Hallucinogenic Drugs
Recent advances in the understanding of the molecular mechanism of action of hallucinogenic drugs, as well as findings obtained in animal models are summarized. Expand
Animal models of serotonergic psychedelics.
The behavioral effects induced by psychedelic drugs in rodent models are reviewed, the translational potential of these findings are discussed, and areas where further research is needed to better understand the molecular mechanisms and neuronal circuits underlying their neuropsychological effects are defined.

Serotonin-Related Psychedelic Drugs
Serotonergic hallucinogens include the prototypical compounds such as mescaline, psilocybin, and LSD, representing the chemical classes of phenethylamines, tryptamines, and ergolines. Known asExpand

A modulatory role of serotonergic agents on dopamine transmission in schizophrenia is reinforced, which may contribute to the therapeutic effects of atypical antipsychotics. Expand

The chief evidence for this position is that clozapine (CLOZ) does not differ from typical antipsychotic drugs in these regards but is more effective than typical neuroleptic drugs. Expand
LSD and the phenethylamine hallucinogen DOI are potent partial agonists at 5-HT2A receptors on interneurons in rat piriform cortex.
It is concluded that LSD and DOI, a phenethylamine hallucinogen, act as highly potent partial agonists at cortical 5-HT2A receptors at rat piriform cortical interneurons. Expand
Dreams, hallucinogenic drug states, and schizophrenia: a psychological and biological comparison.
In the present article, certain fundamental areas of convergence between the three states are described and current neurophysiological theories of dream and hallucinogenic drug states are presented, with emphasis upon serotonin neurotransmission. Expand
Alterations in the cortical serotonergic system in schizophrenia: A postmortem study
Previous studies have suggested a disturbance in the cortical serotonergic (5-HT) system in schizophrenia; however, these studies have been confounded by suicide in the patients groups, which inExpand
DOI disruption of prepulse inhibition of startle in the rat is mediated by 5-HT(2A) and not by 5-HT(2C) receptors.
The view that MDL 100,907 may be a novel atypical antipsychotic is supported and the hypothesis that the 5-HT(2A) receptor is involved in the modulation of sensorimotor gating is supported. Expand
Lysergic acid diethylamide and 2,5-dimethoxy-4-methylamphetamine are partial agonists at serotonin receptors linked to phosphoinositide hydrolysis.
LSD partially antagonized the effect of 5-HT in the choroid plexus, consistent with a partial agonist effect at the 5- HT-1c receptor in this tissue. Expand
The dopamine receptor: differential binding of d-LSD and related agents to agonist and antagonist states.
It is observed that d-LSD interacts with considerable affinity at the dopamine receptor, which suggests that it is a mixed agonist-antagonist, which is consistent with its interactions with the dopamine-sensitive adenylate cyclase. Expand

The disease which thus evokes these new and wonderful talents and operations of the mind may be compared to an earthquake which, by convulsing the upper strata of our globe, throws upon its surfaceExpand
Schizophrenics show spatial working memory deficits.
It is demonstrated that schizophrenics are impaired on spatial delayed-response tasks, analogous to those that have been used to assess the working memory function of the dorsolateral prefrontal cortex in rhesus monkeys, and that this deficit is modality independent. Expand
