Neutrino oscillations and gamma-ray bursts [PDF]
The Astrophysical Journal, 1998 If the ordinary neutrinos oscillate into a sterile flavor in a manner consistent with the Super-Kamiokande data on the zenith-angle dependence of atmospheric mu-neutrino flux, an energy sufficient to power a typical cosmic gamma-ray burst (GRB) (about 10^

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.

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.

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.

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 ...
