Inhibition of Inhibition in Visual Cortex: The Logic of Connections Between Molecularly Distinct Interneurons (2013, positive): “The reciprocal connections among Pvalb cells but not Sst cells is another striking difference between the two cell-types, which may allow Pvalb cells to control their own firing rate, as well as pace and synchronize each other during gamma-oscillations[48].”
Frontiers in Integrative Neuroscience Integrative Neuroscience Neural Synchrony in Cortical Networks: History, Concept and Current Status (neutral): “Through this additional function they assume a pivotal role in the temporal structuring and coordination of neuronal responses (Cardin et al., 2009; Sohal et al., 2009; for a review see Bartos et al., 2007).”
Exploring mechanisms of spontaneous functional connectivity in MEG: How delayed network interactions lead to structured amplitude envelopes of band-pass filtered oscillations (2014, positive): “…of experimental and theoretical studies showing that neural activity at the population level usually exhibits oscillations with a moderate level of synchrony, in particular in the gamma frequency range (30–80 Hz) (Bartos et al., 2007; Borgers and Kopell, 2003; Brunel, 2000; Brunel and Wang, 2003).”
Common circuit defect of excitatory-inhibitory balance in mouse models of autism (2009, positive): “These findings lead to a model of a network of interconnected inhibitory neurons, namely the PV-basket cells, which generate the γ -oscillations [31].”
Different Origins of Gamma Rhythm and High-Gamma Activity in Macaque Visual Cortex (2011, background): “Several mechanisms have been proposed for the generation of gamma rhythms, typically involving a network of inhibitory interneurons with or without reciprocal connections with pyramidal cells (ING and PING networks; [39–43], for reviews see [44,45]).”
A second function of gamma-frequency oscillations: a E%-max winner-take-all mechanism selects which cells fire (2009, background): “Importantly, inhibition itself is modulated at gamma frequency (Soltesz and Deschênes, 1993); indeed, gamma oscillations appears to arise through a feedback process in which principal cells excite interneurons, which then inhibit the principal cells (Miles, 1990; Fisahn et al., 1998; Bartos et al., ”
High-frequency brain activity and muscle artifacts in MEG/EEG: a review and recommendations (2013, background): “Finally, patients undergoing iEEG procedures are usually medicated with drugs that have some interaction with high-frequency activity, which is thought to reflect the excitation-inhibition balance in the brain (Traub et al., 1996; Brunel and Wang, 2003; Bartos et al., 2007).”
Neurophysiological and Computational Principles of Cortical Rhythms in Cognition (2010, background): “Given such input variations, and the high heterogeneity of both cellular and synaptic properties in interneurons (887), how can synchronous oscillations be maintained robustly? Modeling studies suggest that synchrony can be more robustly realized in spite of heterogeneity when GABAA receptor-mediate”
