The role of gamma oscillations in central nervous system diseases: Mechanism and treatment

open access: yesFrontiers in Cellular Neuroscience, 2022
Gamma oscillation is the synchronization with a frequency of 30–90 Hz of neural oscillations, which are rhythmic electric processes of neuron groups in the brain.

Parietal gamma oscillations decreased in cognitive biotype of depression [PDF]

open access: yesScientific Reports
Cognitive biotype in depression has long been associated with abnormalities in neural oscillations. Among them, gamma oscillations are widely observed correlates of cognitive dysfunction. However, whether gamma oscillations implement causal mechanisms of

Impaired In Vivo Gamma Oscillations in the Medial Entorhinal Cortex of Knock-in Alzheimer Model

open access: yesFrontiers in Systems Neuroscience, 2017
The entorhinal cortex (EC) has bidirectional connections with the hippocampus and plays a critical role in memory formation and retrieval. EC is one of the most vulnerable regions in the brain in early stages of Alzheimer’s disease (AD), a ...

Do cortical gamma oscillations promote or suppress perception? An under-asked question with an over-assumed answer

open access: yesFrontiers in Human Neuroscience, 2013
Cortical gamma oscillations occur alongside perceptual processes, and in proportion to perceptual salience. They have a number of properties that make them ideal candidates to explain perception, including incorporating synchronised discharges of neural ...

Aberrant hippocampal gamma oscillations in a mouse model of fragile X syndrome: insights from in vitro slice models [PDF]

open access: yesMolecular Autism
Background Fragile X syndrome (FXS) is the most common inherited intellectual disability, caused by the loss of fragile X mental retardation protein (FMRP), which regulates neuronal signaling and plasticity.

Cortico-striatal gamma oscillations are modulated by dopamine D3 receptors in dyskinetic rats [PDF]

open access: yesNeural Regeneration Research
Long-term levodopa administration can lead to the development of levodopa-induced dyskinesia. Gamma oscillations are a widely recognized hallmark of abnormal neural electrical activity in levodopa-induced dyskinesia.

Gamma oscillations weaken with age in healthy elderly in human EEG

open access: yesNeuroImage, 2020
Gamma rhythms (~20–70 ​Hz) are abnormal in mental disorders such as autism and schizophrenia in humans, and Alzheimer’s disease (AD) models in rodents. However, the effect of normal aging on these oscillations is unknown, especially for elderly subjects ...

Bidirectionally Regulating Gamma Oscillations in Wilson-Cowan Model by Self-Feedback Loops: A Computational Study

open access: yesFrontiers in Systems Neuroscience, 2022
The Wilson-Cowan model can emulate gamma oscillations, and thus is extensively used to research the generation of gamma oscillations closely related to cognitive functions. Previous studies have revealed that excitatory and inhibitory inputs to the model

Integration, coincidence detection and resonance in networks of spiking neurons expressing Gamma oscillations and asynchronous states.

open access: yesPLoS Computational Biology, 2021
Gamma oscillations are widely seen in the awake and sleeping cerebral cortex, but the exact role of these oscillations is still debated. Here, we used biophysical models to examine how Gamma oscillations may participate to the processing of afferent ...

Gamma oscillations in human primary somatosensory cortex reflect pain perception. [PDF]

open access: yesPLoS 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
