High Frequency Oscillations as Neuronal Substrate of Priming and Learning

Contemporary research in cognitive neuroscience suggests that induced high frequency synchronized neuronal activity in the gamma band range (>25Hz) is the neuronal mechanism of the formation of so-called Hebbian cell assemblies (networks). By means of learning paradigms, we were able to investigate the formation of cortical networks and their re-activation during memory retrieval. We demonstrated that synchronized neuronal activity acts as an important neuronal substrate of various mnemonic phenomena, e.g., repetition priming and information maintenance.
