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 ...
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 ...
Gamma-band oscillations in fronto-central areas during performance of a sensorimotor integration task: A qEEG coherence study
(ELSEVIER IRELAND LTD, 2010)
This study aimed to elucidate electrophysiological and cortical mechanisms involved in anticipatory actions when 23 healthy right-handed subjects had to catch a free falling object by qEEG gamma-band (30-100 Hz). It is ...
Cross-frequency interaction of the eye-movement related LFP signals in V1 of freely viewing monkeys
(2013)
Recent studies have emphasized the functional role of neuronal activity underlying oscillatory local field potential (LFP) signals during visual processing in natural conditions. While functionally relevant components in ...
Beta Oscillations Distinguish Between Two Forms of Mental Imagery While Gamma and Theta Activity Reflects Auditory Attention
(2018)
Visual sensory processing of external events decreases when attention is internally oriented toward self-generated thoughts and also differences in attenuation have been shown depending on the thought’s modality (visual ...
Dopamine Modulates Delta-Gamma Phase-Amplitude Coupling in the Prefrontal Cortex of Behaving Rats
(Frontiers in Bioscience, 2017-05)
Dopamine release and phase-amplitude cross-frequency coupling (CFC) have independently been implicated in prefrontal cortex (PFC) functioning. To causally investigate whether dopamine release affects phase-amplitude ...
Abnormal brain oscillations persist after recovery from bipolar depression
(Elsevier France-Editions Scientifiques Medicales Elsevier, 2017)
When directly perturbed in healthy subjects, premotor cortical areas generate electrical oscillations in the beta range (20-40 Hz). In schizophrenia, major depressive disorder and bipolar disorder (BD), these oscillations ...
The Critical Role of Intrinsic Membrane Oscillations
(Karger, 2019-04)
Intrinsic, rhythmic subthreshold oscillations have been described in neurons of regions throughout the brain and have been found to influence the timing of action potentials induced by synaptic inputs. Some oscillations ...
