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.

Gamma oscillations in human primary somatosensory cortex reflect pain perception. [PDF]
PLoS Biology, 2007 Successful behavior requires selection and preferred processing of relevant sensory information. The cortical representation of relevant sensory information has been related to neuronal oscillations in the gamma frequency band. Pain is of invariably high

The Gamma Oscillation: Master or Slave? [PDF]
Brain Topography, 2009 The idea that gamma enhancement reflects a state of high neuronal excitability and synchrony, critical for active brain operations, sets gamma up as a "master" or executor process that determines whether an input is effectively integrated and an effective output is generated.

Gamma oscillations and episodic memory
Trends in Neurosciences, 2023 Enhanced gamma oscillatory activity (30-80 Hz) accompanies the successful formation and retrieval of episodic memories. While this co-occurrence is well documented, the mechanistic contributions of gamma oscillatory activity to episodic memory remain unclear.

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.

Proteomic measures of gamma oscillations [PDF]
Heliyon, 2019 Gamma oscillations serve complex processes, and the first stage of their generation is the reticular activating system (RAS), which mediates the gamma-activity states of waking and paradoxical sleep. We studied whether the pedunculopontine nucleus (PPN), part of the RAS in which every cell manifests intrinsic gamma oscillations, undergoes changes ...

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 ...
