A single psychotomimetic dose of ketamine decreases thalamocortical spindles and delta oscillations in the sedated rat [PDF]

arXiv, 2020
Background: In patients with psychotic disorders, sleep spindles are reduced, supporting the hypothesis that the thalamus and glutamate receptors play a crucial etio-pathophysiological role, whose underlying mechanisms remain unknown. We hypothesized that a reduced function of NMDA receptors is involved in the spindle deficit observed in schizophrenia.

Antibodies in the Diagnosis, Prognosis, and Prediction of Psychotic Disorders

Schizophrenia bulletin, 2018
Blood-based biomarker discovery for psychotic disorders has yet to impact upon routine clinical practice. In physical disorders antibodies have established roles as diagnostic, prognostic and predictive (theranostic) biomarkers, particularly in disorders
