Oscillatory and fractal biomarkers of human memory
Joseph Rudoler,Michael Kahana,Nora A Herweg · COSYNE 2022
Human direct brain recordings have implicated 4-8 Hz theta-band activity in a wide range of cognitive processes including spatial navigation, working memory, and associative recall (Kahana et al. (2001); Nyhus & Curran (2010)). Yet, many highly-powered memory studies indicate that good memory appears during periods of reduced theta and alpha (8-12 Hz) activity and enhanced high-frequency (>40 Hz activity), a pattern known as the spectral tilt (Burkeet al., 2015). In a meta-analysis of prior work, Herweg et al. (2020) suggest several possible resolutions to these discrepant results:
