Gating of Human Theta Oscillations by a Working Memory Task
Sridhar Raghavachari,Michael J. Kahana,Michael J. Kahana,Daniel S. Rizzuto,Jeremy B. Caplan,Matthew P. Kirschen,Blaise F. D. Bourgeois,Joseph R. Madsen,Joseph R. Madsen,John E. Lisman +9 more
TL;DR: The results suggest that theta oscillations could have an important role in organizing multi-item working memory and reveal a new phenomenon, the cognitive "gating" of a brain oscillation.
Journal ArticleDOI
Gamma Oscillations Correlate with Working Memory Load in Humans
Marc W. Howard,Daniel S. Rizzuto,Jeremy B. Caplan,Joseph R. Madsen,John E. Lisman,R. Aschenbrenner-Scheibe,Andreas Schulze-Bonhage,Michael J. Kahana +7 more
TL;DR: Intracranial recordings from two epileptic patients as they performed a working memory task provided the first evidence that gamma oscillations, widely implicated in perceptual processes, support the maintenance of multiple items in working memory.
Journal ArticleDOI
Reset of human neocortical oscillations during a working memory task
Daniel S. Rizzuto,Joseph R. Madsen,Edward B. Bromfield,Andreas Schulze-Bonhage,D. Seelig,R. Aschenbrenner-Scheibe,Michael J. Kahana +6 more
TL;DR: Findings implicate the reset of brain oscillations in human working memory in the 7- to 16-Hz range after randomly timed stimulus events, suggesting that stimulus events reset the phase of ongoing oscillations.
Journal ArticleDOI
Closed-loop stimulation of temporal cortex rescues functional networks and improves memory.
Youssef Ezzyat,Paul A. Wanda,Deborah F. Levy,Allison Kadel,Ada Aka,Isaac Pedisich,Michael R. Sperling,Ashwini Sharan,Bradley C. Lega,Alexis Burks,Robert E. Gross,Cory S. Inman,Barbara C. Jobst,Mark A. Gorenstein,Kathryn A. Davis,Gregory A. Worrell,Michal T. Kucewicz,Joel M. Stein,Richard Gorniak,Sandhitsu R. Das,Daniel S. Rizzuto,Michael J. Kahana +21 more
TL;DR: A closed-loop system is used to decode and stimulate periods of ineffective encoding, showing that stimulation of lateral temporal cortex can enhance memory and suggesting that such systems may provide a therapeutic approach for treating memory dysfunction.
Journal ArticleDOI
Direct Brain Stimulation Modulates Encoding States and Memory Performance in Humans
Youssef Ezzyat,James E. Kragel,John F. Burke,Deborah F. Levy,Anastasia Lyalenko,Paul A. Wanda,Logan O’Sullivan,Katherine B. Hurley,Stanislav Busygin,Isaac Pedisich,Michael R. Sperling,Gregory A. Worrell,Michal T. Kucewicz,Kathryn A. Davis,Timothy H. Lucas,Cory S. Inman,Bradley C. Lega,Barbara C. Jobst,Sameer A. Sheth,Kareem A. Zaghloul,Michael J. Jutras,Joel M. Stein,Sandhitsu R. Das,Richard Gorniak,Daniel S. Rizzuto,Michael J. Kahana +25 more
TL;DR: The hypothesis that targeted electrical stimulation can modulate neural encoding states and subsequent memory outcomes is tested and the conditions under which stimulation modulates memory are identified, suggesting strategies for therapeutically treating memory dysfunction.
