Strength of gamma rhythm depends on normalization. [PDF]
PLoS Biology, 2013 Neuronal assemblies often exhibit stimulus-induced rhythmic activity in the gamma range (30-80 Hz), whose magnitude depends on the attentional load. This has led to the suggestion that gamma rhythms form dynamic communication channels across cortical ...

The gamma rhythm as a guardian of brain health [PDF]
eLifeGamma oscillations in brain activity (30–150 Hz) have been studied for over 80 years. Although in the past three decades significant progress has been made to try to understand their functional role, a definitive answer regarding their causal implication

Speed controls the amplitude and timing of the hippocampal gamma rhythm. [PDF]
PLoS ONE, 2011 Cortical and hippocampal gamma oscillations have been implicated in many behavioral tasks. The hippocampus is required for spatial navigation where animals run at varying speeds.

Hippocampal theta modulation of neocortical spike times and gamma rhythm: a biophysical model study. [PDF]
PLoS ONE, 2012 The hippocampal theta and neocortical gamma rhythms are two prominent examples of oscillatory neuronal activity. The hippocampus has often been hypothesized to influence neocortical networks by its theta rhythm, and, recently, evidence for such a direct ...

Gamma rhythm in patients with ischemic stroke
Лечащий ВрачBackground. Gamma rhythm plays an important role in enabling cognitive processes. Studies confirm the association of gamma activity with visual and auditory perception, time perception, attention, consciousness and processing of semantic information ...

Period concatenation underlies interactions between gamma and beta rhythms in neocortex [PDF]
Frontiers in Cellular Neuroscience, 2008 The neocortex generates rhythmic electrical activity over a frequency range covering many decades. Specific cognitive and motor states are associated with oscillations in discrete frequency bands within this range, but it is not known whether ...

Different origins of gamma rhythm and high-gamma activity in macaque visual cortex. [PDF]
PLoS Biology, 2011 During cognitive tasks electrical activity in the brain shows changes in power in specific frequency ranges, such as the alpha (8-12 Hz) or gamma (30-80 Hz) bands, as well as in a broad range above ∼80 Hz, called the high-gamma band.

The role of syllabic rhythm in speech perception across languages [PDF]
Scientific ReportsThe insertion of silences at regular intervals restores the intelligibility of English utterances that have been accelerated beyond comprehension, as long as the duration of the resulting speech-silence chunks falls within the theta rhythm of natural ...

Brain gamma rhythm and potential treatment of neurodegenerative disease [PDF]
Journal of Neurorestoratology, 2020 In this mini-review, we illustrate the brain network oscillations in different brain areas, including the medial septal diagonal band complex (MSDB) and hippocampus, especially at gamma frequency bands (γ, 30–80 Hz) and theta frequency bands (θ, 4–12 Hz),

Frontiers in Neuroscience, 2022 Previous studies have demonstrated that open-loop transcranial ultrasound stimulation (TUS) can modulate theta and gamma rhythms of the local field potentials (LFPs) in the mouse hippocampus; however, the manner in which closed-loop TUS with different ...
