Gamma oscillation plasticity is mediated via parvalbumin interneurons [PDF]
Science Advances, 2023 Understanding the plasticity of neuronal networks is an emerging field of (patho-) physiological research, yet the underlying cellular mechanisms remain poorly understood. Gamma oscillations (30 to 80 hertz), a biomarker of cognitive performance, require and potentiate glutamatergic transmission onto parvalbumin-positive interneurons (PVIs)

Recording gamma band oscillations in pedunculopontine nucleus neurons [PDF]
, 2016 Synaptic efferents from the PPN are known to modulate the neuronal activity of several intralaminar thalamic regions (e.g., the centrolateral/ parafascicular; Cl/Pf nucleus).

Suppression of Low-Frequency Gamma Oscillations by Activation of 40-Hz Oscillation [PDF]
Cerebral Cortex, 2021 Abstract Gamma oscillations have received considerable attention owing to their association with cognitive function and various neuropsychiatric disorders. However, interactions of gamma oscillations at different frequency bands in humans remain unclear. In the present magnetoencephalographic study, brain oscillations in a wide frequency

Neuronal oscillations enhance stimulus discrimination by ensuring action potential precision [PDF]
, 2006 Although oscillations in membrane potential are a prominent feature of sensory, motor, and cognitive function, their precise role in signal processing remains elusive.

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

Posterior Beta and Anterior Gamma Oscillations Predict Cognitive Insight [PDF]
, 2009 Pioneering neuroimaging studies on insight have revealed neural correlates of the emotional “Aha!” component of the insight process, but neural substrates of the cognitive component, such as problem restructuring (a key to transformative reasoning ...
