Spatial Representation of Hippocampal Place Cells in a T-Maze with an Aversive Stimulation
The hippocampus contains place cells representing spaces in an environment, and these place cells have been suggested to play a fundamental role in the formation of a cognitive map for spatial processing. However, how alterations in the firing patterns of place cells in response to aversive events encode the locations tied to these aversive events is unknown. Here, we analyzed spiking patterns ...
متن کاملDiscordance of spatial representation in ensembles of hippocampal place cells.
The extent to which small ensembles of neighboring hippocampal neurons alter their spatial firing patterns concurrently in response to stimulus manipulations was examined in young adult rats as well as in aged rats with and without memory impairment. Recordings from CA1 and CA3 cells were taken as rats performed a spatial radial-maze task that employed prominent distal visual stimuli attached t...
متن کاملHippocampal representation in place learning.
The generality of the place-learning impairment associated with hippocampal system damage was challenged using methods of training that permitted subjects to form an individual association between the place of escape and a particular navigational route in an open-field water maze. Both normal rats and rats with fornix lesions (FX rats) acquired this task rapidly, although FX rats were slightly ...
متن کاملHippocampal place cells encode intended destination, and not a discriminative stimulus, in a conditional T-maze task.
The firing of hippocampal place cells encodes instantaneous location but can also reflect where the animal is heading (prospective firing), or where it has just come from (retrospective firing). The current experiment sought to explicitly control the prospective firing of place cells with a visual discriminada in a T-maze. Rats were trained to associate a specific visual stimulus (e.g., a flash...
متن کاملThe Hippocampal Place Cells and Fingerprints of Places: Spatial Representation Animals, Animats and Robots
In this paper we address the problem of autonomous navigation seen from the neuroscience and the robotics point of view. A new topological mapping system is presented. It combines local features (i.e. visual and distance cues) in a unique structure – the “fingerprint of a place” that results in a consistent, compact and distinctive representation. Overall, the results suggest that a process of ...
