Alternating Sequences of Future and Past Behavior Encoded Within Hippocampal Theta Oscillations
… human episodic memory retrieval. Specifically, hippocampal function is critical for representation and storage of sequential information during spatial navigation of animals. Pyramidal neurons in the hippocampus have been found to intuitively encode locations in space, and are thus termed "place …

Phase-locking of neurons in the hippocampus and the medial prefrontal cortex of the rat to the hippocampal theta rhythm
The interactions between cortical and hippocampal circuits are critical for memory formation, yet their basic organization at the neuronal network level is not well understood. Here we investigate the timing relationships between neuronal activity in the medial prefrontal cortex of freely behaving …

Electrophysiological Signatures of Spatial and Temporal Coding in Humans
… the hippocampus). The presence of cortical and hippocampal theta oscillations predicts better subsequent memory and more efficient spatial navigation, but the exact relationship between neural oscillations and the coding of spatial distances and temporal durations are unknown. In this …

A central medullary circuit regulating REM sleep and pontine waves
… REM sleep is composed of tonic features such as hippocampal theta oscillations and skeletal muscle paralysis, which are interleaved with short-lived phasic events such as rapid eye movements, limb twitches, and spike-like pontine (P)-waves. Considered a key hallmark of REM sleep, P-waves are …

Simultaneous activation of multiple memory systems during learning : insights from electrophysiology and modeling
… reported. First, striatal LFPs showed prominent theta-band rhythms that were strongly modulated during behavior. Second, striatal and hippocampal theta rhythms were modulated differently during T-maze performance, and in rats that successfully learned the task, became highly coherent during the …

Granular retrosplenial cortex layer 2/3 generates high frequency oscillation events coupled with hippocampal sharp wave-ripples and Str. LM high gamma
… from brain region to brain region. In the hippocampal CA1 pyramidal layer local field potential (LFP), these processes take the form of theta and sharp wave ripples (SPW-Rs) for encoding and consolidation, respectively. As an animal runs through an environment, neurons become active at …
