WebMay 29, 2015 · We show that, in continuous speech, theta oscillations can flexibly track the syllabic rhythm and temporally organize the phoneme-level response of gamma neurons into a code that enables syllable identification. The tracking of slow speech fluctuations by theta oscillations, and its coupling to gamma-spiking activity both appeared as critical ... WebOct 1, 2010 · The second type of synchronization mechanism seen in the hippocampus during alert behaviors is the relatively fast gamma oscillation (∼25–140 Hz). Gamma oscillations in the hippocampus exhibit their largest amplitude when they are nested within the slower theta oscillations (5, 11, 49, 77).
