Abstract Psilocybin holds strong therapeutic promise for treating major depressive disorder. However, the cellular and molecular substrates underlying its action have not been fully elucidated, especially in the primate brain. We combined multimodal MRI, magnetic resonance spectroscopy (MRS), cerebrospinal fluid (CSF) proteomics and metabolomics, and single-nucleus RNA sequencing (snRNA-seq) to...
General anesthesia induces reversible changes in consciousness through cortical activity and connectivity alterations, yet the functional connectome dynamics underlying propofol-induced unconsciousness remains unclear. We analyze high-density 128-channel electroencephalogram (EEG) from 31 surgical patients using source localization to identify neurobiological connectome signatures of propofol...
The development of ketamine-like rapid antidepressants holds promise for enhancing the therapeutic efficacy of depression, but the underlying cellular and molecular mechanisms remain unclear. Implicated in depression regulation, the neuropeptide pituitary adenylate cyclase-activating polypeptide (PACAP) is investigated here to examine its role in mediating the rapid antidepressant response. The...
Dear Editor, Mindfulness meditation alleviates symptoms of distress, pain, and many chronic diseases.1‒3 In schizophrenic patients, mindfulness intervention leads to better psychosocial functioning,4 improved positive emotions,5 and reduced negative symptoms.6 It is unknown if mindfulness meditation could reduce positive symptoms in the chronic schizophrenia patients. Five male patients,...
