Theta-modulated gamma-band synchronization among activated regions during a verb generation task

Frontiers in Psychology, 2012
Expressive language is complex and involves processing within a distributed network of cortical regions. Functional MRI and magnetoencephalography (MEG) have identified brain areas critical for expressive language, but how these regions communicate ...

Emergence of Relaxation Oscillations in Neurons Interacting With Non-stationary Ambient GABA

Frontiers in Computational Neuroscience, 2018
Dynamics of a homogeneous neural population interacting with active extracellular medium were considered. The corresponding mathematical model was tuned specifically to describe the behavior of interneurons with tonic GABA conductance under the action of

The effect of temporal expectation on the correlations of frontal neural activity with alpha oscillation and sensory-motor latency

Scientific Reports, 2023
In a dynamic environment, we seek to enhance behavioral responses by anticipating future events. Previous studies have shown that the probability distribution of the timing of future events could shape our expectation of event timing; furthermore, the ...

Effect of total sleep deprivation on effective EEG connectivity for young male in resting-state networks in different eye states

Frontiers in Neuroscience, 2023
BackgroundMany studies have investigated the effect of total sleep deprivation (TSD) on resting-state functional networks, especially the default mode network (DMN) and sensorimotor network (SMN), using functional connectivity. While it is known that the

Temporal variations in English Populations of a forest insect pest, the green spruce aphid (Elatobium abietinum), associated with the North Atlantic Oscillation and global warming [PDF]

, 2007
Based on an exceptionally long modern ecological dataset (41 years), it has been possible to show that warm weather in England associated with a positive North Atlantic Oscillation (NAO) index causes the spring migration of the green spruce aphid ...

A continuum model for the dynamics of the phase transition from slow-wave sleep to REM sleep [PDF]

, 2010
Previous studies have shown that activated cortical states (awake and rapid eye-movement (REM) sleep), are associated with increased cholinergic input into the cerebral cortex.

Modulation of cross-frequency coupling by novel and repeated stimuli in the primate ventrolateral prefrontal cortex

Frontiers in Psychology, 2011
Adaptive behavior depends on an animal’s ability to ignore uninformative stimuli, such as repeated presentations of the same stimulus, and, instead, detect informative, novel stimuli in its environment.

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.
