Spatial computation with gamma oscillations [PDF]
Frontiers in Systems Neuroscience, 2014 Gamma oscillations in cortex have been extensively studied with relation to behavior in both humans and animal models; however, their computational role in the processing of behaviorally relevant signals is still not clear.

Human gamma oscillations during slow wave sleep. [PDF]
PLoS ONE, 2012 Neocortical local field potentials have shown that gamma oscillations occur spontaneously during slow-wave sleep (SWS). At the macroscopic EEG level in the human brain, no evidences were reported so far.

Parvalbumin Interneuron Dendrites Enhance Gamma Oscillations [PDF]
SSRN Electronic Journal, 2021 Dendrites are important determinants of the input-output relationship of single neurons, but their role in network computations is not well understood. Here, we used a combination of dendritic patch-clamp recordings and in silico modeling to determine how dendrites of parvalbumin (PV)-expressing basket cells contribute to network oscillations in the ...

Gamma Oscillation in Schizophrenia [PDF]
Psychiatry Investigation, 2011 Dysfunctional neural circuitry has been found to be involved in abnormalities of perception and cognition in patients with schizophrenia. Gamma oscillations are essential for integrating information within neural circuits and have therefore been associated with many perceptual and cognitive processes in healthy human subjects and animals.

Gamma oscillations and schizophrenia [PDF]
Journal of Psychiatry and Neuroscience, 2010 In the last 2 decades, it has become apparent that brain regions communicate by coordinating the firing of populations of neurons. When neurons synchronize their firing, their rhythmic input is reflected in the extracellular field potential as brain oscillations. Rhythmic brain activity in animals and humans can be recorded using noninvasive techniques

Mechanisms of Gamma Oscillations [PDF]
Annual Review of Neuroscience, 2012 Gamma rhythms are commonly observed in many brain regions during both waking and sleep states, yet their functions and mechanisms remain a matter of debate. Here we review the cellular and synaptic mechanisms underlying gamma oscillations and outline empirical questions and controversial conceptual issues.

Gamma Oscillations and Stimulus Selection [PDF]
Neural Computation, 2008 More coherent excitatory stimuli are known to have a competitive advantage over less coherent ones. We show here that this advantage is amplified greatly when the target includes inhibitory interneurons acting via GABAA-receptor-mediated synapses and the coherent input oscillates at gamma frequency.

New Light on Gamma Oscillations [PDF]
Neuron, 2017 Two papers in this issue of Neuron by Saleem et al. (2017) and Storchi et al. (2017) show that increases in background light intensity trigger proportional increases in narrowband gamma oscillations with a peak at 60 Hz in retina, lateral geniculate, and primary visual cortex of the mouse visual system.

Gamma oscillations and photosensitive epilepsy [PDF]
Current Biology, 2017 Certain visual images, even in the absence of motion or flicker, can trigger seizures in patients with photosensitive epilepsy. As of yet, there is no systematic explanation as to why some static images are likely to provoke seizures, while others pose little or no risk.
