Dissociation between the experience-dependent development of hippocampal theta sequences and single-trial phase precession
T Feng, D Silva, DJ Foster - Journal of Neuroscience, 2015 - Soc Neuroscience
Theta sequences are circuit-level activity patterns produced when groups of hippocampal
place cells fire in sequences that reflect a compressed behavioral order of place fields within …

Functionally distinct high and low theta oscillations in the human hippocampus
Based on rodent models, researchers have theorized that the hippocampus supports
episodic memory and navigation via the theta oscillation, a~ 4–10 Hz rhythm that …

Hippocampal theta phases organize the reactivation of large-scale electrophysiological representations during goal-directed navigation
Humans are adept in simultaneously following multiple goals, but the neural mechanisms for
maintaining specific goals and distinguishing them from other goals are incompletely …

Self-generated theta oscillations in the hippocampus
Hippocampal theta rhythm is crucial for spatial memory and is thought to be generated by
extrinsic inputs. In contrast, using a complete rat hippocampus in vitro, we found several …

Coherent coding of spatial position mediated by theta oscillations in the hippocampus and prefrontal cortex
Interactions between the hippocampus (area CA1) and prefrontal cortex (PFC) are crucial for
memory-guided behavior. Theta oscillations (∼ 8 Hz) underlie a key physiological …

Theta phase–specific codes for two-dimensional position, trajectory and heading in the hippocampus
JR Huxter, TJ Senior, K Allen, J Csicsvari - Nature neuroscience, 2008 - nature.com
Temporal coding is a means of representing information by the time, as opposed to the rate,
at which neurons fire. Evidence of temporal coding in the hippocampus comes from place …
