Ketamine, a dissociative anesthetic, induces behavioral and molecular alterations associated with psychosis-like phenotypes. However, the epigenetic mechanisms bridging its cellular effects with behavioral outcomes are poorly defined. Here, we report that ketamine induces histone H3 Ser10 phosphorylation in both hippocampal neurons (HT22 cells) and the mouse hippocampus, an effect primarily...

Repeated exposure to ketamine leads to mental behavioral disorders and cognitive deficits in mice. As a neurotransmitter receptor, dopamine receptor 1 (DRD1) is involved in mental regulation and memory formation. However, the role of DRD1 in ketamine's behavioral disorder and neurotoxicity remains unclear. We found that seven-day ketamine exposure induced anxiety-like, depressive-like behavior...

Psychotic disorders frequently result from repeated ketamine exposure, yet the underlying mechanisms remain elusive. We propose that repeated exposure to ketamine may induce psychotic-like behaviors via DRD1-mediated nuclear signaling pathways. Our investigation focused on phosphorylated DARPP-32 at Thr34, Thr75, and Ser97, alongside transcriptome profiling in both cell and mouse models. We...

Psychotic disorder is a significant consequence of ketamine abuse. However, the molecular mechanisms and biomarkers for this psychotic disorder and associated long-term cognitive impairment remain unclear. To investigate the behavioral changes and comprehensive gene expression alterations in mice following ketamine administration, we employed behavioral testing and RNA sequencing (RNA-seq). We...

Consciousness arises from the spatiotemporal neural dynamics, however, its relationship with neural flexibility and regional specialization remains elusive. We identified a consciousness-related signature marked by shifting spontaneous fluctuations along a unimodal-transmodal cortical axis. This simple signature is sensitive to altered states of consciousness in single individuals, exhibiting...
