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 ...
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 ...
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 ...
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 ...
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 ...
Gamma band activity in the developing parafascicular nucleus
(American Physiological Society, 2012-02)
The parafascicular nucleus (Pf) receives cholinergic input from the pedunculopontine nucleus, part of the reticular activating system involved in waking and rapid eye movement (REM) sleep, and sends projections to the ...
Class II histone deacetylases require P/Q-type Ca2+ channels and CaMKII to maintain gamma oscillations in the pedunculopontine nucleus
(Nature Publishing Group, 2018-12)
Epigenetic mechanisms (i.e., histone post-translational modification and DNA methylation) play a role in regulation of gene expression. The pedunculopontine nucleus (PPN), part of the reticular activating system, manifests ...
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 ...
