Multisensory Control of Hippocampal Spatiotemporal Selectivity
A Sense of Place Hippocampal place cells are believed to be mainly governed by visual and self-motion cues. However, the contribution of sensory cues such as smells, sounds, and textures, etc., is… Expand

Impaired spatial selectivity and intact phase precession in two-dimensional virtual reality
TLDR
We measured rodent hippocampal CA1 neuronal activity during random foraging in a two-dimensional body-fixed VR environment in which only distal visual cues provide reliable spatial information. Expand

Causal Influence of Visual Cues on Hippocampal Directional Selectivity
Hippocampal neurons show selectivity with respect to visual cues in primates, including humans, but this has never been found in rodents. To address this long-standing discrepancy, we measured… Expand

Theta Oscillations in the Human Medial Temporal Lobe during Real-World Ambulatory Movement
The theta rhythm-a slow (6-12 Hz) oscillatory component of the local field potential-plays a critical role in spatial navigation and memory by coordinating the activity of neuronal ensembles within… Expand

Enhancing the Ecological Validity of fMRI Memory Research Using Virtual Reality
TLDR
A mini-review surveys the growing body of fMRI studies that have incorporated VR to address critical questions about human memory. Expand

Reporting Guidelines and Issues to Consider for Using Intracranial Brain Stimulation in Studies of Human Declarative Memory
Participants with stimulating and recording electrodes implanted within the brain for clinical evaluation and treatment provide a rare opportunity to unravel the neuronal correlates of human memory,… Expand

Modulation of human intracranial theta oscillations during freely moving spatial navigation and memory
TLDR
We found that prevalence of theta oscillations within the medial temporal lobe (MTL) during spatial memory and navigation is critically linked to memory performance. Expand

1 Hippocampal Motifs
Dorsal Hippocampal neurons provide an allocentric map of space, characterized by three key properties. First, their firing is spatially selective, termed a rate code. Second, as animals traverse… Expand

Wireless Programmable Recording and Stimulation of Deep Brain Activity in Freely Moving Humans
TLDR
We developed a platform that enables wireless and programmable intracranial electroencephalographic recording and deep brain stimulation integrated with wearable technologies, when used in freely moving humans with implanted neural devices. Expand
