Active inference and epistemic value (2015, background): “We have speculated (Friston, Samothrakis, & Montague, 2012) that these updates may be related to nested electrophysiological oscillations, such as phase coupling between gamma and theta oscillations in prefrontal–hippocampal interactions (Canolty et al., 2006).”
Neural syntax: cell assemblies, synapsembles and readers (2010, neutral): “…short lasting (Engel et al., 2001; Fries, 2005; Gray and Singer, 1989; Whittington et al., 2000; Sirota et al., 2008) and often grouped by slower oscillations (Bragin et al., 1995; Canolty et al., 2006; Chrobak and Buzsáki, 1998; Hasenstaub et al., 2005; Sirota et al., 2008; Steriade, 2006).”
Hippocampal sharp wave‐ripple: A cognitive biomarker for episodic memory and planning (2015, background): “, 2007; Buzs aki and Wang, 2012) and in the hippocampus they occur in several varieties: low-frequency (or “slow”; 30– 80 Hz), mid-frequency (60–120 Hz), and fast or “high” (>100 Hz; epsilon) gamma oscillations (Csicsvari et al., 1999a,b; Canolty et al., 2006; Belluscio et al., 2012).”
The Theta-Gamma Neural Code (2013, positive): “Theta-gamma coupling—Theta-gamma coupling during working memory has been demonstrated in humans both in cortex (Canolty et al., 2006; Lee et al., 2005) and in the hippocampus (van Vugt et al., 2010).”
Updating P300: an integrative theory of P3a and P3b. (2007, neutral): “These activation patterns also may reflect the effects of gamma band signals (Canolty et al., 2006).”
Gamma and Theta Rhythms in Biophysical Models of Hippocampal Circuits (2010, background): “The highfrequency rhythms seen in neocortex (Canolty et al., 2006) and hippocampus and striatum (Tort et al., 2008) are not considered gamma in this mechanistically based nomenclature.”
High-frequency brain activity and muscle artifacts in MEG/EEG: a review and recommendations (2013, methodology): “, 2012) and cross-frequency coupling (Canolty et al., 2006; Florin and Baillet, 2012; Voytek et al., 2013)—become progressively more complex, it is important that artifact-free data are being fed into these algorithms.”
Cross-frequency coupling supports multi-item working memory in the human hippocampus (2010, methodology): “First, the averagephaseφ( z) of the lower-frequency oscillation corresponding to a maximum amplitude of the high-frequency oscillation was estimated according to a previously suggested method (19) (for details, see below).”
Theta–gamma coupling increases during the learning of item–context associations (2009, background): “Phaseamplitude CFCs have been described in mice (8, 9, 26), rats (7), monkeys (4), and humans (5, 24, 25) and in multiple brain regions including neocortex (4, 5, 25), hippocampus (7), and basal ganglia (6, 24).”
Surrogate data for hypothesis testing of physical systems (2018, background): “[172] used time-shifting to demonstrate that an observed coupling strength between theta and high gamma oscillations in the human brain falls to much lower levels at large time lags, proving that this coupling was a significant observation.”
