Journal ArticleDOI
High gamma power is phase-locked to theta oscillations in human neocortex.
Ryan T. Canolty,Erik Edwards,Erik Edwards,Sarang S. Dalal,Maryam Soltani,Maryam Soltani,Srikantan S. Nagarajan,Heidi E. Kirsch,Mitchel S. Berger,Nicholas M. Barbaro,Robert T. Knight +10 more
TL;DR: The results indicate that transient coupling between low- and high-frequency brain rhythms coordinates activity in distributed cortical areas, providing a mechanism for effective communication during cognitive processing in humans.
Journal ArticleDOI
Five-dimensional neuroimaging: Localization of the time-frequency dynamics of cortical activity
Sarang S. Dalal,Adrian G. Guggisberg,Adrian G. Guggisberg,Erik Edwards,Erik Edwards,Kensuke Sekihara,Anne M. Findlay,Ryan T. Canolty,Mitchel S. Berger,Robert T. Knight,Nicholas M. Barbaro,Heidi E. Kirsch,Srikantan S. Nagarajan +12 more
TL;DR: This method enables the ultimate promise of MEG and EEG for five-dimensional imaging of space, time, and frequency activity in the brain and renders it applicable for widespread studies of human cortical dynamics during cognition.
Journal ArticleDOI
Task-related gamma-band dynamics from an intracerebral perspective: review and implications for surface EEG and MEG.
Karim Jerbi,Tomás Ossandón,Carlos M. Hamamé,S. Senova,S. Senova,Sarang S. Dalal,Julien Jung,Lorella Minotti,Olivier Bertrand,Alain Berthoz,Philippe Kahane,Jean-Philippe Lachaux +11 more
TL;DR: The characteristics of invasive data acquired from implanted epilepsy patients using stereotactic‐electroencephalography (SEEG) and electrocorticography (ECoG) and the use of spectral analysis to reveal task‐related modulations in multiple frequency components are discussed.
Journal ArticleDOI
Spatiotemporal dynamics of word processing in the human brain.
Ryan T. Canolty,Maryam Soltani,Maryam Soltani,Sarang S. Dalal,Erik Edwards,Erik Edwards,Erik Edwards,Nina F. Dronkers,Srikantan S. Nagarajan,Heidi E. Kirsch,Nicholas M. Barbaro,Robert T. Knight +11 more
TL;DR: Details on the first few hundred milliseconds of the spatiotemporal evolution of cortical activity during word processing are provided to provide evidence consistent with the hypothesis that an oscillatory hierarchy coordinates the flow of information between distinct cortical regions during goal-directed behavior.
Journal ArticleDOI
Spatiotemporal imaging of cortical activation during verb generation and picture naming
Erik Edwards,Srikantan S. Nagarajan,Sarang S. Dalal,Ryan T. Canolty,Heidi E. Kirsch,Nicholas M. Barbaro,Robert T. Knight +6 more
TL;DR: Novel evidence is provided for the role of premotor cortex in speech perception and of Wernicke's and surrounding cortex inspeech production, and a "dual ventral stream" hybrid of leading speech perception models is given.
