The medial septum controls hippocampal supra-theta oscillations
Nature Communications, 2023 Hippocampal theta oscillations orchestrate faster beta-to-gamma oscillations facilitating the segmentation of neural representations during navigation and episodic memory.

eLife, 2015 Neural computations underlying cognitive functions require calibration of the strength of excitatory and inhibitory synaptic connections and are associated with modulation of gamma frequency oscillations in network activity.

MEG studies of motor cortex gamma oscillations: Evidence for a gamma fingerprint in the brain?
Frontiers in Human Neuroscience, 2013 The human motor cortex exhibits transient bursts of high frequency gamma oscillations in the 60 to 90 Hz range during movement. It has been proposed that gamma oscillations generally reflect local intracortical activity. However, movement-evoked gamma is

Brain Sciences, 2020 Autism spectrum disorder (ASD) is a behaviorally diagnosed neurodevelopmental condition of unknown pathology. Research suggests that abnormalities of elecltroencephalogram (EEG) gamma oscillations may provide a biomarker of the condition.

Firing rate models for gamma oscillations [PDF]
Journal of Neurophysiology, 2019 Gamma oscillations are readily observed in a variety of brain regions during both waking and sleeping states. Computational models of gamma oscillations typically involve simulations of large networks of synaptically coupled spiking units. These networks can exhibit strongly synchronized gamma behavior, whereby neurons fire in near synchrony on every ...

Gamma Oscillations and Emotional Memory [PDF]
, 2022 AbstractIncreased visual gamma band activity is known to relate to memory and encoding in cognitive tasks and has been shown to be present during arousing compared to neutral stimulus processing. Here, we set out to investigate whether gamma activity is stronger for later remembered compared to later forgotten emotional pictures.

Gamma oscillations in cognitive disorders
Current Opinion in Neurobiology, 2018 Gamma oscillations (∼25-100 Hz) are believed to play a role in cognition. Accordingly, aberrant gamma oscillations have been observed in several cognitive disorders, including Alzheimer's disease and Fragile X syndrome. Here, we review how recent results showing abnormal gamma rhythms in Alzheimer's disease and Fragile X syndrome help reveal links ...

Gamma-oscillations from bench to bed [PDF]
Clinical Neurophysiology, 2012 In the presurgical evaluation of patients with pharmacoresistant epilepsies, the borders between disciplines tend to oscillate. In particular, the necessity to evaluate the functional capacity of a cortical area that has been shown to be epileptogenic and is thus being considered for resection often makes it impossible not to trespass between ...

Frontiers 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 ...

Autaptic connections and synaptic depression constrain and promote gamma oscillations.
PLoS ONE, 2014 Computational models of gamma oscillations have helped increase our understanding of the mechanisms that shape these 40-80 Hz cortical rhythms. Evidence suggests that interneurons known as basket cells are responsible for the generation of gamma ...
