Cortical Oscillations During Memory Encoding Predict Successful Retrieval

We examined the neurophysiological correlates of memory encoding that lead to successful retrieval. Previous work has demonstrated that changes in intracranial ERPs and fMRI BOLD signals predict subsequent recall in episodic memory tasks (Fernandez et al., 1999; Wagner et al., 1998). Recent work has shown that in free recall, 32–48Hz (gamma) phase synchrony in the medial temporal lobe (MTL) during study predicts subsequent recall (Fell et al., 2001).
