EEG Gamma Activity Differentiates Episodic Memory Test Performance in Human Subjects

This study examined EEG activity during challenging, standardized memory tasks (NIH Toolbox, 2013), and if EEG waveforms displayed localized patterns of activity related to behavioral performance. Spectral density results highlight significant (p < .05) differences in gamma activity (25-40 Hz; memory practice vs. memory test) recorded from 9 electrode locations.
