Does the dopamine hypothesis explain schizophrenia?
- Psychology, MedicineReviews in the neurosciences

It is argued that the current model of aberrant salience explains psychosis in schizophrenia and provides a plausible linkage between the pharmacological and cognitive aspects of the disease.
From prediction error to psychosis: ketamine as a pharmacological model of delusions
- Psychology, MedicineJournal of psychopharmacology
- 2007
It is suggested that ketamine may provide an appropriate model to investigate the formative stages of symptom evolution in schizophrenia, and thereby provide a window into the earliest and otherwise inaccessible aspects of the disease process.

Functional neuroimaging of pathophysiological mesolimbic dopamine system and aberrant motivational salience in schizophrenia
- Psychology, Biology
- 2017
Overall, the increased bottom-up activation of the vStr may result from an intensified recruitment of this region during exaggerated assignment of salience to the conditioned rewards irrespective of the context, and the finding of disturbed cortico-striatal functional interaction in schizophrenic patients is in line with the dysconnection hypothesis of schizophrenia.

Evidence links greater dopamine synthesis capacity to poorer cognitive performance and altered frontal cortical function measured using functional imaging during cognitive tasks, and the nature of other neurofunctional alterations in the disorder, in particular in the serotonergic system and neuroinflammation is reviewed.

- Psychology, MedicineSchizophrenia bulletin

The dopamine hypothesis of schizophrenia-version III is synthesized into a comprehensive framework that links risk factors, including pregnancy and obstetric complications, stress and trauma, drug use, and genes, to increased presynaptic striatal dopaminergic function.

Hyperactivity of Associations in Psychosis
- Psychology, MedicineThe Australian and New Zealand journal of psychiatry
- 1989
This essay has dealt exclusively with the positive (productive) symptoms of psychosis, and their treatment, and briefly traced the origin of the idea that hyperactive associations of thought (i.e. of inductive inference) play an important part in the psychology of acute psychosis.
Psychosis as a state of aberrant salience: a framework linking biology, phenomenology, and pharmacology in schizophrenia.
- Psychology, MedicineThe American journal of psychiatry
- 2003
A heuristic framework for linking the psychological and biological in psychosis is provided and it is proposed that a dysregulated, hyperdopaminergic state, at a "brain" level of description and analysis, leads to an aberrant assignment of salience to the elements of one's experience, at an "mind" level.

It is suggested that the pharmacological characteristics of the hypothetical learning process involved in generating psychotic symptoms are analogous to those of a simpler learning process, defineable in animal experiments — namely, the reward component in instrumental conditioning.

- Psychology, MedicineThe American journal of psychiatry

It is predicted that the atypical antipsychotic effect can be produced by appropriate modulation of the D(2) receptor alone; the blockade of other receptors is neither necessary nor sufficient.

The serotonin‐dopamine antagonists may prove to have many other uses in psychiatry beyond schizophrenia because of their low propensity to cause extrapyramidal symptoms and their pharmacologic mechanism of action may be more complex than only strong 5‐HT2A and weak D2 block.

Elevated synaptic dopamine was predictive of good treatment response of positive symptoms to antipsychotic drugs and increased stimulation of D(2) receptors by dopamine in schizophrenia, consistent with increased phasic activity of dopaminergic neurons.
