Theta rhythm of navigation: link between path integration and landmark navigation, episodic and semantic memory

G Buzsáki - Hippocampus, 2005 - Wiley Online Library
Five key topics have been reverberating in hippocampal‐entorhinal cortex (EC) research
over the past five decades: episodic and semantic memory, path integration (“dead …

What is the function of hippocampal theta rhythm?—Linking behavioral data to phasic properties of field potential and unit recording data

ME Hasselmo - Hippocampus, 2005 - Wiley Online Library
The extensive physiological data on hippocampal theta rhythm provide an opportunity to
evaluate hypotheses about the role of theta rhythm for hippocampal network function …

Complete replication of hepatitis C virus in cell culture

BD Lindenbach, MJ Evans, AJ Syder, B Wolk… - Science, 2005 - science.org
Many aspects of the hepatitis C virus (HCV) life cycle have not been reproduced in cell
culture, which has slowed research progress on this important human pathogen. Here, we …

Independent codes for spatial and episodic memory in hippocampal neuronal ensembles

S Leutgeb, JK Leutgeb, CA Barnes, EI Moser… - Science, 2005 - science.org
Hippocampal neurons were recorded under conditions in which the recording chamber was
varied but its location remained unchanged versus conditions in which an identical chamber …

Attractor dynamics in the hippocampal representation of the local environment

TJ Wills, C Lever, F Cacucci, N Burgess, J O'Keefe - Science, 2005 - science.org
Memories are thought to be attractor states of neuronal representations, with the
hippocampus a likely substrate for context-dependent episodic memories. However, such …

Dual phase and rate coding in hippocampal place cells: theoretical significance and relationship to entorhinal grid cells

J O'keefe, N Burgess - Hippocampus, 2005 - Wiley Online Library
We review the ideas and data behind the hypothesis that hippocampal pyramidal cells
encode information by their phase of firing relative to the theta rhythm of the EEG. Particular …

The theta/gamma discrete phase code occuring during the hippocampal phase precession may be a more general brain coding scheme

J Lisman - Hippocampus, 2005 - Wiley Online Library
In the hippocampus, oscillations in the theta and gamma frequency range occur together
and interact in several ways, indicating that they are part of a common functional system. It is …

Self‐motion and the origin of differential spatial scaling along the septo‐temporal axis of the hippocampus

AP Maurer, SR VanRhoads, GR Sutherland… - …, 2005 - Wiley Online Library
Spatial scaling of place specific activity in the hippocampus varies systematically from the
septal pole (high resolution) to the temporal pole (low resolution). Place fields get …

The temporal context model in spatial navigation and relational learning: toward a common explanation of medial temporal lobe function across domains.

MW Howard, MS Fotedar, AV Datey… - Psychological …, 2005 - psycnet.apa.org
The medial temporal lobe (MTL) has been studied extensively at all levels of analysis, yet its
function remains unclear. Theory regarding the cognitive function of the MTL has centered …

Analyzing functional connectivity using a network likelihood model of ensemble neural spiking activity

M Okatan, MA Wilson, EN Brown - Neural computation, 2005 - direct.mit.edu
