Your brain's health is written in the tiny fluctuations of its signals. Scientists call it Brain Signal Variability (BSV) — a key marker of adaptability, creativity, and resilience.
BSV Metrics Explained
Metrics include entropy measures (approximate entropy, sample entropy) and network analysis via graph theory, describing how efficiently brain regions communicate.
Healthy Brain Entropy Levels
Entropy reflects a balance of order and unpredictability — too low and neural activity becomes rigid; the healthy zone sits in between.
