Theta-burst microstimulation in the human entorhinal area improves memory specificity.
Ali S Titiz,Michael R H Hill,Michael R H Hill,Emily A. Mankin,Zahra M. Aghajan,Dawn Eliashiv,Natalia Tchemodanov,Uri Maoz,Uri Maoz,John M. Stern,Michelle Tran,Peter J Schuette,Eric Behnke,Nanthia Suthana,Itzhak Fried +14 more
TL;DR: It is suggested that microstimulation with physiologic level currents—a radical departure from commonly used deep brain stimulation protocols—is sufficient to modulate human behavior and provides an avenue for refined interrogation of the circuits involved in human memory.
Speed modulation of hippocampal theta frequency correlates with spatial memory performance
Gregory R. Richard,Ali S Titiz,Anna L. Tyler,Gregory L. Holmes,Rod C. Scott,Pierre-Pascal Lenck-Santini +5 more
TL;DR: Investigating whether hippocampal speed‐theta integration influences spatial memory and whether it could account for the memory deficits observed in TLE rats reveals that speed/theta frequency correlation with performance cannot merely be explained by the direct influence of speed on behavior.

Stimulation of the right entorhinal white matter enhances visual memory encoding in humans.
Emily A. Mankin,Zahra M. Aghajan,Peter J Schuette,Michelle Tran,Natalia Tchemodanov,Ali S Titiz,Guldamla Kalender,Dawn Eliashiv,John M. Stern,Shennan A. Weiss,Dylan Kirsch,Barbara J. Knowlton,Itzhak Fried,Nanthia Suthana +13 more
TL;DR: It is found that stimulation of right entorhinal white matter during learning had a beneficial effect on subsequent memory, while stimulation of adjacent gray matter or left-sided stimulation was ineffective.

Short-Range Temporal Interactions in Sleep; Hippocampal Spike Avalanches Support a Large Milieu of Sequential Activity Including Replay
TL;DR: This work decodes sequential firing structure within spike avalanches of all pyramidal cells recorded in sleeping rats after running in a circular track and finds that short sequences that combine into multiple long sequences capture the majority of the sequential structure during sleep, including replay of hippocampal place cells.
Joint time-frequency analysis of EEG signals based on a phase-space interpretation of the recording process
Markus E. Testorf,Barbara C. Jobst,Jonathan K. Kleen,Ali S Titiz,Guillory Sa,RC Scott,Krzysztof A. Bujarski,David W. Roberts,Gregory L. Holmes,P-P Lenck-Santini +9 more
TL;DR: For simultaneously improving the time and frequency resolution, and for representing the EEG of several channels or trials in a single time-frequency plane, a multichannel matching pursuit algorithm is used.
