Replay of cortical spiking sequences during human memory retrieval

AP Vaz, JH Wittig Jr, SK Inati, KA Zaghloul - Science, 2020 - science.org
Episodic memory retrieval is thought to rely on the replay of past experiences, yet it remains
unknown how human single-unit activity is temporally organized during episodic memory …

[HTML][HTML] Backbone spiking sequence as a basis for preplay, replay, and default states in human cortex

AP Vaz, JH Wittig Jr, SK Inati, KA Zaghloul - Nature Communications, 2023 - nature.com
Sequences of spiking activity have been heavily implicated as potential substrates of
memory formation and retrieval across many species. A parallel line of recent evidence also …

[PDF][PDF] Large-scale communication in the human brain is rhythmically modulated through alpha coherence

JI Chapeton, R Haque, JH Wittig, SK Inati, KA Zaghloul - Current Biology, 2019 - cell.com
Recent evidence has suggested that coherent neuronal oscillations may serve as a gating
mechanism for flexibly modulating communication between brain regions. For this to occur, …

The medial temporal lobe supports the quality of visual short-term memory representation

…, JI Chapeton, S Bhasin, C Zawora, JH Wittig Jr… - Nature Human …, 2023 - nature.com
The quality of short-term memory (STM) underlies our ability to recall the exact details of a
recent event, yet how the human brain enables this core cognitive function remains poorly …

[HTML][HTML] Changing temporal context in human temporal lobe promotes memory of distinct episodes

MM El-Kalliny, JH Wittig Jr, TC Sheehan… - Nature …, 2019 - nature.com
Memories of experiences that occur around the same time are linked together by a shared
temporal context, represented by shared patterns of neural activity. However, shared temporal …

Dual origins of measured phase-amplitude coupling reveal distinct neural mechanisms underlying episodic memory in the human cortex

AP Vaz, RB Yaffe, JH Wittig Jr, SK Inati, KA Zaghloul - Neuroimage, 2017 - Elsevier
Phase-amplitude coupling (PAC) is hypothesized to coordinate neural activity, but its role in
successful memory formation in the human cortex is unknown. Measures of PAC are difficult …

Ripples reflect a spectrum of synchronous spiking activity in human anterior temporal lobe

APS Tong, AP Vaz, JH Wittig, SK Inati, KA Zaghloul - Elife, 2021 - elifesciences.org
Direct brain recordings have provided important insights into how high-frequency activity
captured through intracranial EEG (iEEG) supports human memory retrieval. The extent to …

[PDF][PDF] Human cortical neurons in the anterior temporal lobe reinstate spiking activity during verbal memory retrieval

AI Jang, JH Wittig, SK Inati, KA Zaghloul - Current Biology, 2017 - cell.com
When we recall an experience, we rely upon the associations that we formed during the
experience, such as those among objects, time, and place [1]. These associations are better …

Neuronal spiking responses to direct electrical microstimulation in the human cortex

D Youssef, JH Wittig, S Jackson, SK Inati… - Journal of …, 2023 - Soc Neuroscience
Microstimulation can modulate the activity of individual neurons to affect behavior, but the
effects of stimulation on neuronal spiking are complex and remain poorly understood. This is …
