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 measuredExpand

Dynamics of cortical dendritic membrane potential and spikes in freely behaving rats
Dendrites are more active than expected Dendrites occupy more than 90% of neuronal tissue. However, it has not been possible to measure distal dendritic membrane potential and spiking in vivo over aExpand

Visual cues determine hippocampal directional selectivity
Both spatial and directional information are necessary for navigation. Rodent hippocampal neurons show spatial selectivity in all environments1, but directional tuning only on linear paths2–8.TheExpand

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 traverseExpand

Multisensory Representations of Space in Hippocampal CA1
Author(s): Acharya, Lavanya | Advisor(s): Mehta, Mayank R; Cohen, Mark | Abstract: How the brain represents space is a long-standing question, whose answer is most likely to be found within theExpand

Dynamics of Cortical Dendritic Membrane Potential and Spikes in Freely Behaving Rats
Neural activity in vivo is primarily measured using extracellular somatic spikes, which provide limited information about neural computation. Hence, it is necessary to record from neuronal dendrites,Expand
