Theta phase precession in hippocampal neuronal populations and the compression of temporal sequences
Large‐scale parallel recordings are made use of to clarify and extend the finding that a cell's spike activity advances to earlier phases of the theta cycle as the rat passes through the cell's place field, and to show Granule cells of the fascia dentata are also modulated by theta.
Deciphering the hippocampal polyglot: the hippocampus as a path integration system.
A hypothesis of how the path integration system may operate at the neuronal level is proposed, and it appears that viewpoint-specific visual information becomes secondarily bound to this structure by associative learning.
Replay of Neuronal Firing Sequences in Rat Hippocampus During Sleep Following Spatial Experience
The correlated activity of rat hippocampal pyramidal cells during sleep reflects the activity of those cells during earlier spatial exploration and this memory for temporal order of neuronal firing could be produced by an interaction between the temporal integration properties of long-term potentiation and the phase shifting of spike activity with respect to the hippocampal theta rhythm.
Dynamics of Mismatch Correction in the Hippocampal Ensemble Code for Space: Interaction between Path Integration and Environmental Cues
Although map alignment can be controlled by landmarks, hippocampal neurons do not explicitly represent objects or events, data suggest that when mismatches occur, path integration and external cues interact competitively to control place-cell firing.
A Model of the Neural Basis of the Rat's Sense of Direction
A model is formulated of the neural mechanisms underlying the head direction system, built out of simple ingredients, but it behaves in a sophisticated way and is consistent with most of the observed properties of real head direction cells.
An Information-Theoretic Approach to Deciphering the Hippocampal Code
Applying the formula, systematic differences in the information content of hippocampal "place cells" in different experimental conditions are found.
Paradoxical Effects of External Modulation of Inhibitory Interneurons
The neocortex, hippocampus, and several other brain regions contain populations of excitatory principal cells with recurrent connections and strong interactions with local inhibitory interneurons, and the dynamic behavior of this type of network is modeled, including external inputs.
Population dynamics and theta rhythm phase precession of hippocampal place cell firing: A spiking neuron model
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 information content and reliability of hippocampal CA1 neurons: Effects of visual input
The effects of darkness on quantitative spatial firing characteristics of 235 hippocampal CA1 “complex spike” (CS) cells were studied in young and old Fischer‐344 rats during food‐motivated
The Cerebellum
In addition to its direct role in motor control, the cerebellum is necessary for several types of motor learning, most notably learning to adjust to changes in sensorimotor relationships.
