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 ...
Increased Prefrontal-Parietal EEG Gamma Band Correlation during Motor Imagery in Expert Video Game Players
(Universidad de Costa Rica, 2014)
Synchronization of neural activity across cortical areas correlates with conscious perception
(SOC NEUROSCIENCE, 2007)
Subliminal stimuli can be deeply processed and activate similar brain areas as consciously perceived stimuli. This raises the question which signatures of neural activity critically differentiate conscious from unconscious ...
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 ...
Rhythmic activities of the brain: quantifying the high complexity of beta and gamma oscillations during visuomotor tasks
(American Institute of Physics, 2018-07)
Electroencephalography (EEG) signals depict the electrical activity that take place at the surface of the brain, and provide an important tool for understanding a variety of cognitive processes. The EEG are the product of ...
Bottom-up gamma and bipolar disorder, clinical and neuroepigenetic implications
(Wiley Blackwell Publishing, Inc, 2019-03)
Objectives: This limited review examines the role of the reticular activating system (RAS), especially the pedunculopontine nucleus (PPN), one site of origin of bottom-up gamma, in the symptoms of bipolar disorder (BD).Methods: ...
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 ...
Pedunculopontine nucleus gamma band activity-preconscious awareness, waking, and REM sleep
(Frontiers, 2014-10)
The pedunculopontine nucleus (PPN) is a major component of the reticular activating system (RAS) that regulates waking and REM sleep, states of high-frequency EEG activity. Recently,we described the presence of high ...
Meditation Increases the Entropy of Brain Oscillatory Activity
(Pergamon-Elsevier Science Ltd, 2020-04-01)
We address the hypothesis that the entropy of neural dynamics indexes the intensity and quality of conscious content. Previous work established that serotonergic psychedelics can have a dysregulating effect on brain activity, ...
