Theta oscillations in human memory

NA Herweg, EA Solomon, MJ Kahana - Trends in cognitive sciences, 2020 - cell.com
Theta frequency (4–8 Hz) fluctuations of the local field potential have long been implicated
in learning and memory. Human studies of episodic memory, however, have provided mixed …

Oscillations and episodic memory: addressing the synchronization/desynchronization conundrum

S Hanslmayr, BP Staresina, H Bowman - Trends in neurosciences, 2016 - cell.com
Brain oscillations are one of the core mechanisms underlying episodic memory. However,
while some studies highlight the role of synchronized oscillatory activity, others highlight the …

Closed-loop stimulation of temporal cortex rescues functional networks and improves memory

Y Ezzyat, PA Wanda, DF Levy, A Kadel, A Aka… - Nature …, 2018 - nature.com
Memory failures are frustrating and often the result of ineffective encoding. One approach to
improving memory outcomes is through direct modulation of brain activity with electrical …

Direct brain stimulation modulates encoding states and memory performance in humans

Y Ezzyat, JE Kragel, JF Burke, DF Levy, A Lyalenko… - Current biology, 2017 - cell.com
People often forget information because they fail to effectively encode it. Here, we test the
hypothesis that targeted electrical stimulation can modulate neural encoding states and …

Widespread theta synchrony and high-frequency desynchronization underlies enhanced cognition

EA Solomon, JE Kragel, MR Sperling, A Sharan… - Nature …, 2017 - nature.com
The idea that synchronous neural activity underlies cognition has driven an extensive body
of research in human and animal neuroscience. Yet, insufficient data on intracranial …

Interacting networks of brain regions underlie human spatial navigation: a review and novel synthesis of the literature

AD Ekstrom, DJ Huffman… - Journal of …, 2017 - journals.physiology.org
Navigation is an inherently dynamic and multimodal process, making isolation of the unique
cognitive components underlying it challenging. The assumptions of much of the literature …

Directional coupling of slow and fast hippocampal gamma with neocortical alpha/beta oscillations in human episodic memory

BJ Griffiths, G Parish, F Roux… - Proceedings of the …, 2019 - National Acad Sciences
Episodic memories hinge upon our ability to process a wide range of multisensory
information and bind this information into a coherent, memorable representation. On a …

[HTML][HTML] Frequency-specific electrophysiologic correlates of resting state fMRI networks

CD Hacker, AZ Snyder, M Pahwa, M Corbetta… - Neuroimage, 2017 - Elsevier
Resting state functional MRI (R-fMRI) studies have shown that slow (< 0.1 Hz), intrinsic
fluctuations of the blood oxygen level dependent (BOLD) signal are temporally correlated …

Dynamic theta networks in the human medial temporal lobe support episodic memory

EA Solomon, JM Stein, S Das, R Gorniak, MR Sperling… - Current Biology, 2019 - cell.com
The medial temporal lobe (MTL) is a locus of episodic memory in the human brain. It is
comprised of cytologically distinct subregions that, in concert, give rise to successful …

Decreases in theta and increases in high frequency activity underlie associative memory encoding

JA Greenberg, JF Burke, R Haque, MJ Kahana… - Neuroimage, 2015 - Elsevier
Episodic memory encoding refers to the cognitive process by which items and their
associated contexts are stored in memory. To investigate changes directly attributed to the …
