The neural and molecular basis of working memory function in psychosis: a multimodal PET-fMRI study.

Molecular psychiatry

Working memory (WM) deficits predict clinical and functional outcomes in schizophrenia but are poorly understood and unaddressed by existing treatments. WM encoding and WM retrieval have not been investigated in schizophrenia without the confounds of illness chronicity or the...

Dopamine and glutamate in schizophrenia: biology, symptoms and treatment.

World psychiatry : official journal of the World Psychiatric Association (WPA)

McCutcheon RA, Krystal JH, Howes OD.
PMID: 31922684
World Psychiatry. 2020 Feb;19(1):15-33. doi: 10.1002/wps.20693.

Glutamate and dopamine systems play distinct roles in terms of neuronal signalling, yet both have been proposed to contribute significantly to the pathophysiology of schizophrenia. In this paper we assess research that has implicated both systems in the aetiology...

The neurobiology of treatment-resistant schizophrenia: paths to antipsychotic resistance and a roadmap for future research.

NPJ schizophrenia

NPJ Schizophr. 2020 Jan 07;6(1):1. doi: 10.1038/s41537-019-0090-z.

Treatment-resistant schizophrenia (TRS), the persistence of positive symptoms despite ≥2 trials of adequate dose and duration of antipsychotic medication with documented adherence, is a serious clinical problem with heterogeneous presentations. TRS can vary in its onset (at the first...

Variability in Action Selection Relates to Striatal Dopamine 2/3 Receptor Availability in Humans: A PET Neuroimaging Study Using Reinforcement Learning and Active Inference Models.

Cerebral cortex (New York, N.Y. : 1991)

Adams RA, Moutoussis M, Nour MM, Dahoun T, Lewis D, Illingworth B, Veronese M, Mathys C, de Boer L, Guitart-Masip M, Friston KJ, Howes OD, Roiser JP.

Cereb Cortex. 2020 May 18;30(6):3573-3589. doi: 10.1093/cercor/bhz327.

Choosing actions that result in advantageous outcomes is a fundamental function of nervous systems. All computational decision-making models contain a mechanism that controls the variability of (or confidence in) action selection, but its neural implementation is unclear-especially in humans....

The effects of voice content on stress reactivity: A simulation paradigm of auditory verbal hallucinations.

Schizophrenia research

Baumeister D, Peters E, Pruessner J, Howes O, Chadwick P.
PMID: 31377050
Schizophr Res. 2019 Aug 01; doi: 10.1016/j.schres.2019.07.019. Epub 2019 Aug 01.

OBJECTIVES: Psychosis is associated with increased subjective and altered endocrine and autonomic nervous system stress-reactivity. Psychosis patients often experience auditory verbal hallucinations, with negative voice content being particularly associated with distress. The present study developed a voice-simulation paradigm and...

Psychosis is a heterogeneous psychiatric condition for which a multitude of risk and protective factors have been suggested. This umbrella review aimed to classify the strength of evidence for the associations between each factor and psychotic disorders whilst controlling...

Enhanced Dopamine in Prodromal Schizophrenia (EDiPS): a new animal model of relevance to schizophrenia.

NPJ schizophrenia

Petty A, Cui X, Tesiram Y, Kirik D, Howes O, Eyles D.

One of the most robust neurochemical abnormalities reported in patients living with schizophrenia is an increase in dopamine (DA) synthesis and release in the dorsal striatum (DS). Importantly, it appears that this increase progresses as a patient transitions from...
