Neuronal gamma-band synchronization as a fundamental process in cortical computation. (2009, background): “Similarly activated network states, with fine spatial resolution, are created by attentional top-down control (Fries et al. 2001, 2008b; Bichot et al. 2005; Taylor et al. 2005; Womelsdorf et al. 2006).”
An improved index of phase-synchronization for electrophysiological data in the presence of volume-conduction, noise and sample-size bias (2011, neutral): “It is often stated that the direct coherence estimator is positively biased (e.g., see Benignus, 1969; Maris et al., 2007; Vinck et al., 2010b; Womelsdorf et al., 2006).”
Thalamocortical oscillations (2006, background): “Gamma activity is associated with attentiveness (Rougeul-Buser et al., 1975; Bouyer et al., 1981), focused arousal (Sheer, 1989), sensory perception (Gray et al., 1989), movement (Murthy and Fetz, 1992; Pfurtscheller and Neuper, 1992) and prediction (Womelsdorf et al., 2006).”
Spectral Changes in Cortical Surface Potentials during Motor Movement (2007, background): “, 2005), that (as we demonstrate here) high-frequency changes are a specific correlate of local behavior (Hoogenboom et al., 2006; Womelsdorf et al., 2006), and we postulate that they may directly reflect an increase in local cortical computation.”
Transient induced gamma-band response in EEG as a manifestation of miniature saccades. (2008, background): “It is clear that gamma activity widely exists in the brain and is crucial for its function (Canolty et al., 2008; Gray et al., 1989; Varela et al., 2001; Womelsdorf et al., 2006).”
Gamma-band synchronization in the neocortex: novel analysis methods and their application to sensory and motivational systems (2013, methodology): “Several methods exist to measure spike-LFP phase consistency (Fries et al., 1997; Jarvis & Mitra, 2001; Pesaran et al., 2002; Womelsdorf et al., 2006).”
Waking State: Rapid Variations Modulate Neural and Behavioral Responses (2015, neutral): “, 2007), and behavioral performance (Siegle et al., 2014; Womelsdorf et al., 2006).”
A critical role for the right fronto-insular cortex in switching between central-executive and default-mode networks (2008, background): “Several previous studies have shown that there is increased gamma band activity during visual or tactile attention in primates and humans (16, 17), and during human conscious perception [intracranial EEG recordings, (18)].”
Neural correlates of high-gamma oscillations (60–200 Hz) in macaque local field potentials and their potential implications in electrocorticography (2008, background): “…oscillations have been observed during several higher cortical processes such as selective attention (Tiitinen et al., 1993; Fries et al., 2001; Womelsdorf et al., 2006), sensorimotor integration (Murthy and Fetz, 1992; Roelfsema et al., 1997), binding of distributed representations (Gray et…”
Coupling between neuronal firing rate, gamma LFP, and BOLD fMRI is related to interneuronal correlations. (2007, background): “Precise phase-locking has typically been found between spiking activity and gamma LFP in moments of increased attention [32], so it is possible that future work focusing on particular moments of heightened attention might reveal a similar phenomenon in human data.”
Laminar differences in gamma and alpha coherence in the ventral stream (2011, background): “By contrast, attentional effects on firing rates were not significantly different across layers, but there was a significant effect of area, with the largest effects in area V4 (two-way ANOVA, main effect of area [F(2,222) = 9.”
Spontaneous fluctuations in posterior alpha-band EEG activity reflect variability in excitability of human visual areas. (2008, neutral): “…using in vivo recordings in animals (Arieli et al. 1996; Azouz and Gray 1999; Fries et al. 2001; Super et al. 2003; van der Togt et al. 2005, 2006; Womelsdorf et al. 2006), and EEG/ MEG (Rahn and Basar 1993; Ergenoglu et al. 2004; Babiloni et al. 2006) or fMRI techniques in humans (Ress et al.…”
