The contribution of electrical synapses to field potential oscillations in the hippocampal formation
Frontiers in Neural Circuits, 2014 Electrical synapses are a type of cellular membrane junction referred to as gap junctions (GJs). GJs have been regarded as an important component within the neuronal networks that underlie synchronous neuronal activity and field potential oscillations ...

The spectro-contextual encoding and retrieval theory of episodic memory. [PDF]
, 2014 The spectral fingerprint hypothesis, which posits that different frequencies of oscillations underlie different cognitive operations, provides one account for how interactions between brain regions support perceptual and attentive processes (Siegel etal.,

High-frequency neural oscillations and visual processing deficits in schizophrenia [PDF]
, 2013 Visual information is fundamental to how we understand our environment, make predictions, and interact with others. Recent research has underscored the importance of visuo-perceptual dysfunctions for cognitive deficits and pathophysiological processes in

Turning a Negative into a Positive: Ascending GABAergic Control of Cortical Activation and Arousal
Frontiers in Neurology, 2015 Gamma-aminobutyric acid (GABA) is the main inhibitory neurotransmitter in the brain. Recent technological advances have illuminated the role of GABAergic neurons in control of cortical arousal and sleep.

A Microsaccadic Rhythm Modulates Gamma-Band Synchronization and Behavior [PDF]
The Journal of Neuroscience, 2009 Rhythms occur both in neuronal activity and in behavior. Behavioral rhythms abound at frequencies at or below 10 Hz. Neuronal rhythms cover a very wide frequency range, and the phase of neuronal low-frequency rhythms often rhythmically modulates the strength of higher-frequency rhythms, particularly of gamma-band synchronization (GBS).

Gamma Rhythm Analysis and Simulation Using Neuron Models
IFAC-PapersOnLine, 2022 Neural oscillations are electrical activities of the brain measurable at different frequencies. This paper studies the interaction between the fast and slow processes in the brain. We recorded signals intracranially from the simple Wistar rats, performed the signal processing, and computed the correlation between envelopes of the high-frequency gamma ...

Temporal interactions between cortical rhythms
Frontiers in Neuroscience, 2008 Multiple local neuronal circuits support different, discrete frequencies of network rhythm in neocortex. Relationships between different frequencies correspond to mechanisms designed to minimise interference, couple activity via stable phase interactions,

Modeling rhythmic patterns in the hippocampus
, 2012 We investigate different dynamical regimes of neuronal network in the CA3 area of the hippocampus. The proposed neuronal circuit includes two fast- and two slowly-spiking cells which are interconnected by means of dynamical synapses.

Frontiers in Neurology, 2022 Transcranial alternating current stimulation (tACS) is a relatively new non-invasive brain electrical stimulation method for the treatment of patients with Alzheimer's disease (AD), but it has poor offline effects.
