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 ...
Mechanism behind gamma band activity in the pedunculopontine nucleus
(Wiley, 2011-07)
The pedunculopontine nucleus (PPN), part of the reticular activating system, modulates waking and paradoxical sleep. During waking and paradoxical sleep, EEG responses are characterized by low-amplitude, high-frequency ...
Recording gamma band oscillations in pedunculopontine nucleus neurons
(JoVE, 2016-09)
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). The activation of either the PPN or Cl/Pf nuclei ...
New recurrent deletions in the PPAR gamma and TP53 genes are associated with childhood myelodysplastic syndrome
(Pergamon-Elsevier B.V. Ltd, 2009-01-01)
Myelodysplastic syndrome (MDS) is a rare hematological malignancy in children. It was performed FISH analysis in 19 pediatric MDS patients to investigate deletions involving the PPAR gamma and TP53 genes. Significant losses ...

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 ...
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 ...
Functional differences of low- and high-frequency oscillatory dynamics during illusory border perception
(ELSEVIER, 2010)
Neuronal oscillations are an essential part of several brain processes like perception, memory and attention, but little is known about the simultaneous dynamics of different frequency bands in such processes. Here, we ...
