Gamma band activity in the reticular activating system
(Frontiers Head Office-Online publication, 2012-01)
This review considers recent evidence showing that cells in three regions of the reticular activating system (RAS) exhibit gamma band activity, and describes the mechanisms behind such manifestation. Specifically, we discuss ...
Gamma band activity in the RAS-intracellular mechanism
(Springer, 2014-05)
Gamma band activity participates in sensory perception, problem solving, and memory. This review considers recent evidence showing that cells in the reticular activating system (RAS) exhibit gamma band activity, and describes ...
Intracellular mechanisms modulating gamma band activity in the pedunculopontine nucleus (PPN)
(Wiley Blackwell Publishing, Inc, 2016-06)
The pedunculopontine nucleus is a part of the reticular activating system, and is active during waking and REM sleep. Previous results showed that all PPN cells tested fired maximally at gamma frequencies when depolarized. ...
Cholinergic and glutamatergic agonists induce gamma frequency activity in dorsal subcoeruleus nucleus neurons
(American Physiological Society, 2011-05)
The dorsal subcoeruleus nucleus (SubCD) is involved in generating two signs of rapid eye movement (REM) sleep: muscle atonia and ponto-geniculo-occipital (PGO) waves. We tested the hypothesis that single cell and/or ...
Increased Prefrontal-Parietal EEG Gamma Band Correlation during Motor Imagery in Expert Video Game Players
(2014-11-19)
Abstract. The aim of this study was to characterize the prefrontal-parietal EEG correlation in experienced video game players (VGPs) in relation to individuals with little or no video game experience (NVGPs) during a motor ...
Task-related gamma-band dynamics from an intracerebral perspective: Review and implications for surface EEG and MEG
(2009)
Although non-invasive techniques provide functional activation maps at ever-growing spatiotemporal precision, invasive recordings offer a unique opportunity for direct investigations of the fine-scale properties of neural ...
High-Threshold Ca2+ channels behind gamma band activity in the pedunculopontine nucleus (PPN)
(American Physiological Society and The Physiological Society, 2015-07)
The pedunculopontine nucleus (PPN) is part of the Reticular Activating System, and active during waking and REM sleep. Previous results showed that all PPN cells plateau at gamma frequencies and intrinsic membrane oscillations ...
Membrane electrical activity elicits inositol 1,4,5-trisphosphate-dependent slow Ca2+ signals through a G beta gamma/phosphatidylinositol 3-kinase gamma pathway in skeletal myotubes
(AMER SOC BIOCHEMISTRY MOLECULAR BIOLOGY INC, 2006-04-28)
Tetanic electrical stimulation of myotubes evokes a ryanodine receptor-related fast calcium signal, during the stimulation, followed by a phospholipase C/inositol 1,4,5-trisphosphate-dependent slow calcium signal few seconds ...
Pedunculopontine arousal system physiology– deep brain stimulation (DBS)
(Elsevier Science, 2015-11)
This review describes the wake/sleep symptoms present in Parkinson׳s disease, and the role of the pedunculopontine nucleus in these symptoms. The physiology of PPN cells is important not only because it is a major element ...
Modulation of gamma oscillations in the pedunculopontine nucleus by neuronal calcium sensor protein-1: Relevance to schizophrenia and bipolar disorder
(American Physiological Society, 2015-02)
Reduced levels of gamma-band activity are present in schizophrenia and bipolar disorder patients. In the same disorders, increased neuronal calcium sensor protein-1 (NCS-1) expression was reported in a series of postmortem ...
