Preclinical models of antipsychotic drug action.
One of the main obstacles faced by translational neuroscience is the development of animal models of psychiatric disorders. Behavioural pharmacology studies indicate that psychedelic drugs, such as lysergic acid diethylamide (LSD) and dissociative drugs, such as phencyclidine (PCP), induce in healthy human volunteers psychotic and cognitive symptoms that resemble some of those observed in schiz...
متن کاملDisruption of thalamocortical activity in schizophrenia models: relevance to antipsychotic drug action.
Non-competitive NMDA receptor antagonists are widely used as pharmacological models of schizophrenia due to their ability to evoke the symptoms of the illness. Likewise, serotonergic hallucinogens, acting on 5-HT(2A) receptors, induce perceptual and behavioural alterations possibly related to psychotic symptoms. The neurobiological basis of these alterations is not fully elucidated. Data obtain...
متن کاملReevaluation of the mesolimbic hypothesis of antipsychotic drug action.
Conventional neuroleptic drugs are thought to derive their antipsychotic efficacy through influences on the mesolimbic dopamine (DA) system. In contrast, motor side effects of these drugs are suggested to follow from influences on the nigrostriatal DA system. This conceptualization is based on the assumption that behaviors mediated by the mesolimbic DA system are involved in schizophrenia while...
متن کاملAn investigation of the behavioral mechanisms of antipsychotic action using a drug-drug conditioning paradigm.
Antipsychotic drugs at noncataleptic doses selectively suppress conditioned avoidance response in rats. In our previous study, we had used a two-way active avoidance response paradigm to show that the antipsychotic-induced interoceptive state is one of the mechanisms underlying the avoidance-disruptive effect of antipsychotics. In this study, we sought to further examine this mechanism using a ...
متن کاملRethinking models of psychotropic drug action.
Theoretical assumptions about how psychotropic drugs 'work' are rarely discussed explicitly. In a 'disease-centred model,' drugs are believed to work by acting on a disease process. In contrast, in a 'drug-centred model,' the characteristic physiological, behavioural and subjective effects of drugs are used to define drug action. The therapeutic value of a drug stems from the usefulness of thes...
