High-frequency oscillations (HFOs) reflect rapid, synchronized bursts of neuronal assembly in frequencies extending beyond the traditional gamma bands and provide a testable mechanism for encoding and recalling specific memory items by neuronal assemblies in a given brain region. We explored the role of ripple frequency HFOs (80-200Hz) during verbal word-screening (WS) and free-recall (FR) memory tasks in 20 patients. We statistically determined HFO active channels and responses to a set of 180 words in the WS to compare HFO responses to the same words in the FR. Channels with active and inact
