Electrophysiological and hemodynamic measures of human brain activity have been shown to distinguish between episodes of encoding items that are later recalled versus those that are not recalled (Paller and Wagner, 2002). Using intracranial recordings from 793 widespread cortical and subcortical sites in 10 epileptic patients undergoing invasive monitoring, we compared oscillatory power at frequencies ranging from 2 to 64 Hz as participants studied lists of common nouns. Significant increases in oscillatory power during encoding predicted subsequent recall, with this effect predominantly in the 4-8 Hz (theta) and 28-64 Hz (gamma) frequency bands. Sites exhibiting increased theta activity during successful encoding were clustered in right temporal and frontal cortex, whereas those exhibiting increased gamma activity appeared bilaterally at widespread cortical locations. These findings implicate theta and gamma oscillatory activity, across a widespread network of cortical regions, in the formation of new episodic memories.

Gamma and beta bursts underlie working memory (2016, positive): “It was only by averaging across trials and recording sites that we observed the broad-band, smoothly varying oscillatory power that has been reported previously (Sederberg et al., 2003; Howard et al., 2003; Roux et al., 2012; Roux and Uhlhaas, 2014; Honkanen et al., 2015; Kornblith et al., 2015).”
High-frequency brain activity and muscle artifacts in MEG/EEG: a review and recommendations (2013, background): “…electrodes, 30–60 Hz high-frequency activity correlated positively with memory load in the Sternberg working memory task (Howard et al., 2003); and in another study, highfrequency activity during encoding predicted subsequent recall in frontal and more posterior electrodes (Sederberg et al., 2003).”
The Influences of Emotion on Learning and Memory (2017, background): “This finding was later supported by the revelation of increased theta activity in the right frontal (Friese et al., 2013) and right temporal cortices (Sederberg et al., 2003) and consequently associated with the successful encoding of new information.”
The role of oscillations and synchrony in cortical networks and their putative relevance for the pathophysiology of schizophrenia.

Functional segregation of rostral and caudal hippocampus in associative memory (2025, unknown): “…are widely recognized as key mechanisms for item memory formation and episodic binding, facilitating the integration of individual elements into cohesive memory traces (Hanslmayr et al., 2016; Headley and Weinberger, 2011; Henin et al., 2019; Sederberg et al., 2003; Staresina et al., 2016).”
Why does invasive brain stimulation sometimes improve memory and sometimes impair it? (2024, unknown): “However, it remains an open question if patients could benefit from receiving customized stimulation in relation to neural biomarkers at other non-theta frequencies, such as memory-related high-frequency activity [81,82].”
