A learned map for places and concepts in the human MTL

Nora Alicia Herweg, Lukas Kunz, Daniel R. Schonhaut, Armin Brandt, Paul A. Wanda, Ashwini Dayal Sharan, Michael R. Sperling, Andreas Schulze‐Bonhage, Michael J. Kahana

The paper studies how the human medial temporal lobe (MTL) represents spatial and semantic information through micro-wire recordings, showing that learned representations support navigation and prediction.

Functionally distinct high and low theta oscillations in the human hippocampus

Abhinav Goyal, Jonathan F. Miller, Salman E. Qasim, Andrew J. Watrous, Honghui Zhang, Joel M. Stein, Cory S. Inman, Robert E. Gross, Jon Timothy Willie, Bradley Charles Lega, Jui-Jui Lin, Ashwini Dayal Sharan, Chengyuan Wu, Michael R. Sperling, Sameer Anil Sheth, , Joshua Jacobs

The paper investigates human hippocampal theta oscillations, finding distinct high (8-Hz) and low (3-Hz) frequencies associated with spatial navigation and non-spatial processes respectively.

Reactivated spatial context guides episodic recall

Nora Alicia Herweg, Ashwini Dayal Sharan, Michael R. Sperling, Armin Brandt, Andreas Schulze‐Bonhage, Michael J. Kahana

This study investigates how spatial information is reactivated in the medial temporal lobe during episodic recall and identifies theta oscillations as a shared mechanism for spatial coding and memory retrieval.

Single-neuron representations of spatial targets in humans

Melina Tsitsiklis, Jonathan F. Miller, Salman E. Qasim, Cory S. Inman, Robert E. Gross, Jon Timothy Willie, Elliot H. Smith, Sameer Anil Sheth, Catherine A. Schevon, Michael R. Sperling, Ashwini Dayal Sharan, Joel M. Stein, Joshua Jacobs

This study examines how neurons in the human medial-temporal lobe represent spatial targets during navigation, finding that firing rates change based on target position and heading direction.

Tonic resting-state hubness supports high-frequency activity defined verbal-memory encoding network in epilepsy

Ganne Chaitanya, Walter A. Hinds, James E. Kragel, Xiaosong He, Noah Sideman, Youssef Ezzyat, Michael R. Sperling, Ashwini Dayal Sharan, Joseph I. Tracy

The paper examines how high-frequency gamma activity in epilepsy patients correlates with resting-state BOLD fluctuations, showing distinct hubness in memory encoding networks.

Electrical stimulation in hippocampus and entorhinal cortex impairs spatial and temporal memory

Abhinav Goyal, Jonathan F. Miller, Andrew J. Watrous, Sang Ah Lee, Tom Coffey, Michael R. Sperling, Ashwini Dayal Sharan, Gregory A. Worrell, Brent M Berry, Bradley Charles Lega, Barbara C. Jobst, Kathryn A. Davis, Cory S. Inman, Sameer Anil Sheth, Paul A. Wanda, , Joshua Jacobs

This study uses electrical brain stimulation to show that the medial temporal lobe impairs spatial and temporal memory organization in humans.
