...The increase in frequency suggests that kainate changes the local microcircuit underlying gamma oscillations, reminiscent to that reported in the entorhinal cortex (Middleton et al., 2008)....

...Local network oscillation characteristics differ between models, depending on the involvement of different subsets of interneurons (Hajos et al., 2004; Palhalmi et al., 2004; Brown et al., 2006; Middleton et al., 2008) and different contributions of recurrent excitation (Bartos et al., 2007)....

...…unique interneurons target specific pyramidal cell compartments (somatic or dendritic) that differentially participate in network oscillations in hippocampal area (Chapman and Lacaille, 1999; Maccaferri and McBain, 1996; Pike et al., 2000) and in entorhinal cortex (Middleton et al., 2008)....

...This has been seen in primary auditory and visual cortices as well as parietal regions [50], and is particularly marked in entorhinal cortex in animal models [51]....

...These plastic changes, and in certain areas the very gamma rhythm that may control STDP in the first place, are all dependent on NMDA receptor function [51,54,55]....

...Modeling work has contributed to the understanding of the mechanism of generation of theta rhythmic subthreshold oscillations and spiking patterns [4,9–11,33] in single SCs, and in small networks including SCs and interneurons [8,10,11,37]....

...This mechanism can underlie gamma rhythms in a broad range of frequencies from around 20 Hz up to 70 Hz in the hippocampus (8) but cannot support higher frequencies such as those labeled as ‘‘high gamma’’ previously (9)....

...The basic mechanism of generation of population gamma rhythms by local neuronal circuits reveals an absolute dependence on the influence of fast spiking inhibitory interneurons at the level of principal cell somata (5, 6),with the frequency dependent on the magnitude and kinetics of gamma aminobutyric acid (GABAA) receptor-mediated synaptic events (7)....
