Journal ArticleDOI
Functional control of electrophysiological network architecture using direct neurostimulation in humans
Ankit N. Khambhati,Ari E. Kahn,Ari E. Kahn,Julia Costantini,Youssef Ezzyat,Ethan A. Solomon,Robert E. Gross,Barbara C. Jobst,Sameer A. Sheth,Kareem A. Zaghloul,Gregory A. Worrell,Sarah Seger,Bradley C. Lega,Shennan A. Weiss,Michael R. Sperling,Richard Gorniak,Sandhitsu R. Das,Joel M. Stein,Daniel S. Rizzuto,Michael J. Kahana,Timothy H. Lucas,Kathryn A. Davis,Joseph I. Tracy,Danielle S. Bassett +23 more
TL;DR: The ability to predictably reconfigure patterns of interactions between functional brain areas by modulating the strength and location of stimulation is demonstrated, suggesting that stimulation may be tuned to influence different scales of network interactions driving cognition.
Journal ArticleDOI
Medial temporal lobe functional connectivity predicts stimulation-induced theta power
Ethan A. Solomon,James E. Kragel,Robert E. Gross,Bradley C. Lega,Michael R. Sperling,Gregory A. Worrell,Sameer A. Sheth,Kareem A. Zaghloul,Barbara C. Jobst,Joel M. Stein,S. Das,Richard Gorniak,Cory S. Inman,Sarah Seger,Daniel S. Rizzuto,Michael J. Kahana +15 more
TL;DR: The authors show that the low-frequency functional connectivity profile of a stimulation target predicts where induced theta activity occurs, demonstrating that functional connectivity is predictive of causal changes in the brain, capturing evoked activity across brain regions and frequency bands.
Journal ArticleDOI
Cross-regional phase amplitude coupling supports the encoding of episodic memories.
TL;DR: In this paper, a cross-regional phase amplitude coupling (xPAC) between theta and gamma oscillations was observed in human subjects engaged in mnemonic processing, and the magnitude of xPAC predicted memory encoding success and specific frequencies within the broad 2-9 Hz theta range.
Journal ArticleDOI
Distinct neurophysiological correlates of the fMRI BOLD signal in the hippocampus and neocortex.
Paul F. Hill,Sarah Seger,Hye Bin Yoo,Danielle R. King,David X. Wang,Bradley C. Lega,Michael D. Rugg,Michael D. Rugg +7 more
TL;DR: In this paper, the authors examined the neurophysiological correlates of the fMRI BOLD signal in the hippocampus and neocortex, where differences in neural architecture might result in a different relationship between the respective signals.

Predictive control of electrophysiological network architecture using direct, single-node neurostimulation in humans
Ankit N. Khambhati,Ari E. Kahn,Ari E. Kahn,Julia Costantini,Youssef Ezzyat,Ethan A. Solomon,Robert E. Gross,Barbara C. Jobst,Sameer A. Sheth,Kareem A. Zaghloul,Gregory A.

Tracy,Danielle S. Bassett +23 more
TL;DR: In this paper, the authors use tools from network control theory to examine the dynamic reconfiguration of functionally interacting neuronal ensembles during targeted neuro-stimulation of cortical and subcortical brain structures.
