Entropy analysis can quantify the dynamic states of the brain and reflect its information processing capacity. Nitrous oxide has shown rapid antidepressant effects in treatment-resistant depression (TRD) patients, but its biomarkers are not yet established. We recruited 44 TRD patients and randomly assigned them to two groups: one received a 1-hour nitrous oxide inhalation treatment, while the...
Currently, treatment options for patients with treatment-resistant depression (TRD) are extremely limited. Although the rapid antidepressant effects of nitrous oxide have been preliminarily validated, the underlying neurophysiological mechanisms remain unclear. In this study, we intended to explore impact on brain modules induced by nitrous oxide through a randomized controlled study. A total...
Cannabis is the most frequently used illicit drug worldwide. Although multiple structural MRI studies of individuals with cannabis use (CB) have been undertaken, the reports of the volume alterations in the amygdala, hippocampus, and pallidum are not consistent. This study aims to detect subregion-level morphological alterations, analyze the correlation areas with cannabis usage...
