Interaction of sensory responses with spontaneous depolarization in layer 2/3 barrel cortex
The rodent primary somatosensory cortex is spontaneously active in the form of locally synchronous membrane depolarizations (UP states) separated by quiescent hyperpolarized periods (DOWN states)Expand

Role of experience and oscillations in transforming a rate code into a temporal code
We propose a mechanism by which a temporal code can be generated through an interaction between an asymmetric rate code and oscillatory inhibition that satisfies the temporal order constraints of hebbian learning. Expand

Experience-Dependent Asymmetric Shape of Hippocampal Receptive Fields
We propose a novel parameter, namely, the skewness, or asymmetry, of the shape of a receptive field to characterize two properties of hippocampal place fields. First, a majority of hippocampalExpand

Experience-dependent, asymmetric expansion of hippocampal place fields.
Theories of sequence learning based on temporally asymmetric, Hebbian long-term potentiation predict that during route learning the spatial firing distributions of hippocampal neurons should enlargeExpand

Running Speed Alters the Frequency of Hippocampal Gamma Oscillations
Successful spatial navigation is thought to employ a combination of at least two strategies: the following of landmark cues and path integration. Path integration requires that the brain use theExpand

Multisensory Control of Hippocampal Spatiotemporal Selectivity
A Sense of Place Hippocampal place cells are believed to be mainly governed by visual and self-motion cues. However, the contribution of sensory cues such as smells, sounds, and textures, etc., isExpand

Phase-locking of hippocampal interneurons' membrane potential to neocortical up-down states
During quiet wakefulness and sleep, and under anesthesia, the membrane potentials of neocortical pyramidal neurons show synchronous, slow oscillations, so-called up-down states (UDS), that can beExpand

Speed Controls the Amplitude and Timing of the Hippocampal Gamma Rhythm
Cortical and hippocampal gamma oscillations have been implicated in many behavioral tasks. The hippocampus is required for spatial navigation where animals run at varying speeds. Hence we tested theExpand

Differential responses of hippocampal subfields to cortical up–down states
The connectivity of the hippocampal trisynaptic circuit, formed by the dentate gyrus, the CA3 and the CA1 region, is well characterized anatomically and functionally in vitro. The functionalExpand

Impaired spatial selectivity and intact phase precession in two-dimensional virtual reality
We measured rodent hippocampal CA1 neuronal activity during random foraging in a two-dimensional body-fixed VR environment in which only distal visual cues provide reliable spatial information. Expand
