O'Keefe and Recce [1993] Hippocampus 3:317–330 described an interaction between the hippocampal theta rhythm and the spatial firing of pyramidal cells in the CA1 region of the rat hippocampus: they found that a cell's spike activity advances to earlier phases of the theta cycle as the rat passes through the cell's place field. The present study makes use of large‐scale parallel recordings to clarify and extend this finding in several ways: 1) Most CA1 pyramidal cells show maximal activity at…

Population dynamics and theta rhythm phase precession of hippocampal place cell firing: A spiking neuron model
- BiologyHippocampus
- 1996
A neural network model based on integrate‐and‐fire neurons that accounts for the phase shift of neuronal spiking arises in the model as a result of asymmetric spread of activation through the network, caused by asymmetry in the synaptic interactions.
Spatial selectivity and theta phase precession in CA1 interneurons
- BiologyHippocampus
- 2007
The role of interneurons may extend beyond a global damping of the network by participating in a finely‐tuned local processing with the pyramidal cells, as well as the influence of the detailed shape of the inhibitory oscillation on a model of phase precession.
Hippocampus-independent phase precession in entorhinal grid cells
- BiologyNature
- 2008
It is shown that phase precession is expressed independently of the hippocampus in spatially modulated grid cells in layer II of medial entorhinal cortex, one synapse upstream of the amygdala, raising the possibility that hippocampal phasePrecession is inherited from entorHinal cortex.
Independence of the unimodal tuning of firing rate from theta phase precession in hippocampal place cells
- BiologyBiological Cybernetics

Simulations show that the regulable coupling of dendritic with the somatic compartment is critically responsible for the generation of unimodal firing rate profile in place cells, independent of phase precession.
Understanding hippocampal phase precession and phase relationships using phase response curves
- Biology
- 2008
It is shown that a certain phase response curve is consistent with phase relationships between CA1 pyramidal neurons and their inputs, and it has potential to be useful for studying the interaction of single hippocampal neurons with the oscillatory activity of the network.
Theta phase precession emerges from a hybrid computational model of a CA3 place cell
- BiologyCognitive Neurodynamics
- 2007
A neurobiologically based computational model of the emergence of theta phase precession in CA3 is presented in which the responses of a single model CA3 pyramidal cell are examined in the context of stimulation by realistic afferent spike trains and suggests that no one single factor offers a complete explanation of the phenomenon.
Theta phase precession beyond the hippocampus

How ventral striatal phase precession can advance the understanding of behaviors thought to depend on interactions between the hippocampus and the vStr, such as conditioned place preference and context-dependent reinstatement is outlined.
A Temporal Mechanism for Generating the Phase Precession of Hippocampal Place Cells
- BiologyJournal of Computational Neuroscience
- 2004
A minimal biophysical model of the phase precession of place cells in region CA3 of the hippocampus is presented and it is reported that phase precess is a temporally, and not spatially, controlled process.
Modeling Inheritance of Phase Precession in the Hippocampal Formation
- BiologyThe Journal of Neuroscience
- 2014
The inheritance model can explain why phase precession is observed throughout the hippocampal formation and other areas of the brain and suggests that the spatial distribution of field centers of a population of phase-precessing input cells determines, not only the place selectivity, but also the characteristics ofphase precession of the targeted output cell.
Bimodality of theta phase precession in hippocampal place cells in freely running rats.
- BiologyJournal of neurophysiology

The firing of hippocampal principal cells in freely running rats exhibits a progressive phase retardation as the animal passes through a cell's "place" field. This "phase precession" is more complex…

Phase relationship between hippocampal place units and the EEG theta rhythm

The phase was highly correlated with spatial location and less well correlated with temporal aspects of behavior, such as the time after place field entry, and the characteristics of the phase shift constrain the models that define the construction of place fields.

Theta-field in freely moving rats is generated by a rhythmic somatic inhibition phase-shifted with a distal apical-dendritic excitation, proposed to be the synaptic process generating the theta- field potentials in the urethananesthetized or curarized rat.

The theta rhythm usually exists in unanesthetized animals and becomes prominent after various kinds of afferent stimulation or after stimulation of the midbrain reticular formation, and in this descriptive sense the hippocampal EEG bears an inverse relationship to the neocortical EEG.
