High-frequency oscillations (HFOs) have commonly been associated with the pathophysiology of epilepsy but recent evidence points to a cognitive role of neural activities in the gamma, ripple and fast ripple frequency bands (60-500Hz). In particular, encoding and recall of memory induces bursts of HFOs at distinct frequency and latency depending on the cortical location. How these local neural assembly activities are globally coordinated across the brain during memory processing remains elusive. Intracranial local field potential recordings from epilepsy patients were used to detect individual
