Frequency Following Response (FFR) is the brain's tendency to synchronize its dominant EEG rhythm with the frequency of an external stimulus (e.g., binaural beats, flickering light, rhythmic sound). It underlies neural entrainment and state-shifting technologies.
Key Points
- •Entrainment — external rhythm "pulls" internal rhythm toward it
- •Stimulus types — auditory (binaural beats), visual (flicker), tactile
- •Individual variability — not everyone responds equally
