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, ...
Language acquisition in premature and full-term infants
(NATL ACAD SCIENCES, 2010)
We tested healthy preterm (born near 28 +/- 2 weeks of gestational age) and full-term infants at various different ages. We compared the two populations on the development of a language acquisition landmark, namely, the ...
Implications of gamma band activity in the pedunculopontine nucleus
(Springer Wien, 2016-07)
The fact that the pedunculopontine nucleus (PPN) is part of the reticular activating system places it in a unique position to modulate sensory input and fight-or-flight responses. Arousing stimuli simultaneously activate ...
Gamma oscillations in the pedunculopontine nucleus are regulated by F-actin: neuroepigenetic implications
(American Physiological Society, 2020-02)
The pedunculopontine nucleus (PPN) is part of the reticular activating system (RAS) in charge of arousal and rapid eye movement sleep. The presence of high-frequency membrane oscillations in the gamma-band range in the PPN ...
Cortical Oscillatory Activity Is Critical for Working Memory as Revealed by Deficits in Early-Onset Schizophrenia
(SOC NEUROSCIENCE, 2009)
Impairments in working memory (WM) are a core cognitive deficit in schizophrenia. Neurophysiological models suggest that deficits during WM maintenance in schizophrenia may be explained by abnormalities in the GABAergic ...
Gamma band oscillations under influence of bromazepam during a sensorimotor integration task: An EEG coherence study
(ELSEVIER IRELAND LTD, 2010)
The goal of the present study was to explore the dynamics of the gamma band using the coherence of the quantitative electroencephalography (qEEG) in a sensorimotor integration task and the influence of the neuromodulator ...
Differential effects of HDAC inhibitors on PPN oscillatory activity in vivo
(Pergamon-Elsevier Science Ltd, 2020-03)
The pedunculopontine nucleus (PPN) has long been known to be part of the reticular activating system (RAS) in charge of arousal and REM sleep. We previously showed that in vitro exposure to a HDAC Class I and II mixed ...
Selective Coupling between Theta Phase and Neocortical Fast Gamma Oscillations during REM-Sleep in Mice
(2011)
Background: The mammalian brain expresses a wide range of state-dependent network oscillations which vary in frequency
and spatial extension. Such rhythms can entrain multiple neurons into coherent patterns of activity, ...
Visualization of fast calcium oscillations in the parafascicular nucleus
(Springer, 2013-04)
The parafascicular nucleus (Pf) is an ascending target of the pedunculopontine nucleus (PPN) and is part of the “non-specific” intralaminar thalamus. The PPN, part of the reticular activating system, is mainly involved in ...
Brain to brain coupling in the gamma band as a marker of shared intentionality
(Frontiers Media, 2020)
Cooperation and competition are two ways of social interaction keys to life in society. Recent EEG-based hyperscanning studies reveal that cooperative and competitive interactions induce an increase in interbrain coupling. ...
