Journal ArticleDOI
Neuronal long-range temporal correlations and avalanche dynamics are correlated with behavioral scaling laws
J. Matias Palva,Alexander Zhigalov,Jonni Hirvonen,Onerva Korhonen,Klaus Linkenkaer-Hansen,Satu Palva,Satu Palva +6 more
TL;DR: In this article, the authors used source reconstructed magneto-and electroencephalographic recordings to characterize the dynamics of ongoing cortical activity and found robust power-law scaling in neuronal LRTCs and avalanches in resting-state data and during the performance of audiovisual threshold stimulus detection tasks.
Journal ArticleDOI
Phase and amplitude correlations in resting-state activity in human stereotactical EEG recordings.
TL;DR: It is demonstrated here that with CW referencing, the superior anatomical accuracy of SEEG can be leveraged to yield accurate quantification and qualitatively novel insight into phase and amplitude interactions in human brain activity.
Journal ArticleDOI
Whole-Brain Source-Reconstructed MEG-Data Reveal Reduced Long-Range Synchronization in Chronic Schizophrenia
TL;DR: Test data highlight that ScZ is associated with a profound disruption of transient synchronization, providing critical support for the notion that core aspect of the pathophysiology arises from an impairment in coordination of distributed neural activity.
Journal ArticleDOI
Long-range phase synchronization of high-frequency oscillations in human cortex.
Gabriele Arnulfo,Gabriele Arnulfo,Sheng H. Wang,Sheng H. Wang,Vladislav Myrov,Vladislav Myrov,Benedetta Toselli,Jonni Hirvonen,Marco Fato,Lino Nobili,Lino Nobili,Francesco Cardinale,Annalisa Rubino,Alexander Zhigalov,Alexander Zhigalov,Satu Palva,Satu Palva,Jaakko Matias Palva +17 more
TL;DR: It is shown, using human intracerebral recordings, that 100–400 Hz high-frequency oscillations (HFOs) may be synchronized between widely distributed brain regions and exhibits reliable connectivity patterns that show stable community structuring.
Journal ArticleDOI
Dynamic large-scale network synchronization from perception to action
TL;DR: It is found that perceiving and reporting of weak somatosensory stimuli was correlated with sustained strengthening of large-scale phase synchronization concurrently in delta/theta- (3-7 Hz) and gamma- (40-60 Hz) frequency bands, suggesting that large- scale network synchronization may coordinate neuronal processing across brain regions during perception, decision making, and responding to weak somatoensory stimulus.
