New and Distinct Hippocampal Place Codes Are Generated Without Grid Cell Inputs

New and Distinct Hippocampal Place Codes Are Generated Without Grid Cell Inputs. This Neuron video abstract describes an experiment that used inactivation of the medial septal area to suppress the spatial firing patterns of grid cells to determine the role of grid cells in hippocampal place coding. The results of this study suggest that spatial inputs from grid cells are not required for hippocampal place cells to form a distinct spatial representation of a new environment.
