From perception to action: phase-locked gamma oscillations correlate with reaction times in a speeded response task

BMC Neuroscience, 2007
Background Phase-locked gamma oscillations have so far mainly been described in relation to perceptual processes such as sensation, attention or memory matching.

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.

Alpha band oscillations track temporal orienting of attention [PDF]

, 2010
Introduction: Recent investigations using field-potential recordings in visual and auditory cortices have shown that oscillatory activity in neuronal ensembles become entrained to the timing of rhythmically presented stimuli according to their modality ...

CaMKIV over-expression boosts cortical 4-7 Hz oscillations during learning and 1-4 Hz delta oscillations during sleep

Molecular Brain, 2010
Mounting evidence suggests that neural oscillations are related to the learning and consolidation of newly formed memory in the mammalian brain. Four to seven Hertz (4-7 Hz) oscillations in the prefrontal cortex are also postulated to be involved in ...

Investigation of stability in a two-delay model of the ultradian oscillations in glucose-insulin regulation [PDF]

, 2015
In this paper, a two-delay model for the ultradian oscillatory behaviour of the glucose-insulin regulation system is studied. Hill functions are introduced to model nonlinear physiological interactions within this system and ranges on parameters ...

Gamma Oscillations in Rat Hippocampal Subregions Dentate Gyrus, CA3, CA1, and Subiculum Underlie Associative Memory Encoding

Cell Reports, 2017
Neuronal oscillations in the rat hippocampus relate to both memory and locomotion, raising the question of how these cognitive and behavioral correlates interact to determine the oscillatory network state of this region. Here, rats freely locomoted while

A computational study on altered theta-gamma coupling during learning and phase coding [PDF]

, 2012
There is considerable interest in the role of coupling between theta and gamma oscillations in the brain in the context of learning and memory. Here we have used a neural network model which is capable of producing coupling of theta phase to gamma ...

Contribution of transcranial oscillatory stimulation to research on neural networks: An emphasis on hippocampo-neocortical rhythms

Frontiers in Human Neuroscience, 2013
EEG rhythms reflect the synchronized activity of underlying biological neuronal network oscillations, and certain predominant frequencies are typically linked to certain behavioral states.

Sleep spindle maturity promotes slow oscillation-spindle coupling across child and adolescent development

eLife, 2023
The synchronization of canonical fast sleep spindle activity (12.5–16 Hz, adult-like) precisely during the slow oscillation (0.5–1 Hz) up peak is considered an essential feature of adult non-rapid eye movement sleep. However, there is little knowledge on

Parkinsonian beta oscillations in the external globus pallidus and their relationship with subthalamic nucleus activity [PDF]

, 2008
Inappropriately synchronized beta (β) oscillations (15–30 Hz) in the subthalamic nucleus (STN) accompany movement difficulties in idiopathic Parkinson's disease (PD).
