Entropy and Network Integration: Quantifying Brain Dynamic States Under Psilocybin
Graph theory analysis reveals that psilocybin increases brain entropy and global signal integration, breaking down rigid modular boundaries.
Measuring Neural Signal Diversity
Using Lempel-Ziv complexity and Shannon entropy measures, neuroscientists quantify the richness and diversity of brain activity patterns during altered conscious states.
Global Functional Integration vs Modular Isolation
Under resting conditions, the brain operates in discrete, highly modular subnetworks. Psilocybin recruits long-range connections, merging subnetworks into a unified global workspace.
