Whether propofol-induced loss of consciousness (LOC) reflects a single thalamocortical transition or involves temporally dissociable local and interregional dynamics remains unclear. Using stereo-electroencephalography recordings from the anterior nucleus of the thalamus, prefrontal cortex, and temporal cortex during anesthesia induction, we quantified permutation entropy, spectral power,...
The search for neurophysiological markers of consciousness and their neural substrates remains a focal point in neuroscience research. The integrated information theory (IIT) provides a promising quantitative framework for consciousness assessment, but computational limitations of existing Φ estimation methods hinder an in-depth understanding of large-scale cortical integration. Here, we...
Recent advancements in the study of mushroom-derived tryptamines, particularly psilocybin and its metabolite psilocin, highlight their unique psychedelic properties and potential therapeutic applications, especially for mental health conditions like depression. This study examines how the position of the hydroxyl group on the indole ring affects the 5-HT2A receptor activity and psychedelic-like...
