Efficient phase coding in hippocampal place cells
Published 2020-09-01“…To answer this, we developed a conductance-based spiking model for phase precession, a phase code of external space exhibited by hippocampal place cells. Our model accounted for several experimental observations on place cell firing and electrophysiology: the emergence of phase precession from exact spike timings of conductance-based models with neuron-specific ion channels and receptors; biological heterogeneities in neural components and excitability; the emergence of subthreshold voltage ramp, increased firing rate, enhanced theta power within the place field; a signature reduction in extracellular theta frequency compared to its intracellular counterpart; and experience-dependent asymmetry in firing-rate profile. …”

The place-cell representation of volumetric space in rats
Published 2020-02-01“…Here the authors record place cells in rats climbing through a 3D environment and report that they represent this space with 3D fields that are elongated along the axes of the environment and encode the vertical dimension less accurately.…”

Protocol for remapping of place cells in disease mouse models
Published 2021-09-01“…Summary: Hippocampal place cells and entorhinal grid cells exhibit distinct spike patterns in different environments called “remapping,” and we have recently shown that remapping of place cells becomes disrupted in a mouse model of Alzheimer's disease. …”

Place-cell capacity and volatility with grid-like inputs
Published 2021“…<jats:p>What factors constrain the arrangement of the multiple fields of a place cell? By modeling place cells as perceptrons that act on multiscale periodic grid-cell inputs, we analytically enumerate a place cell’s <jats:italic>repertoire</jats:italic> – how many field arrangements it can realize without external cues while its grid inputs are unique – and derive its <jats:italic>capacity</jats:italic> – the spatial range over which it can achieve any field arrangement. …”
