(The layer II entorhinal stellate neurons are the projection neurons that are the main source of the perforant path into the hippocampus.)

| Grid cell spatial firing models (Zilli 2012) | |
| This package contains MATLAB implementations of most models (published from 2005 to 2011) of the hexagonal firing field arrangement of grid cells. | |
| Modular grid cell responses as a basis for hippocampal remapping (Monaco and Abbott 2011) | |
| "Hippocampal place fields, the local regions of activity recorded from place cells in exploring rodents, can undergo large changes in relative location during remapping. This process would appear to require some form of modulated global input. Grid-cell responses recorded from layer II of medial entorhinal cortex in rats have been observed to realign concurrently with hippocampal remapping, making them a candidate input source. However, this realignment occurs coherently across colocalized ensembles of grid cells (Fyhn et al., 2007). The hypothesized entorhinal contribution to remapping depends on whether this coherence extends to all grid cells, which is currently unknown. We study whether dividing grid cells into small numbers of independently realigning modules can both account for this localized coherence and allow for hippocampal remapping. ..." | |

| Development of spiking grid cells and place cells in the entorhinal-hippocampal system to represent positions in large spaces | |
| Synthesis of spatial tuning functions from theta cell spike trains (Welday et al., 2011) | |
| A single compartment model reproduces the firing rate maps of place, grid, and boundary cells by receiving inhibitory inputs from theta cells. The theta cell spike trains are modulated by the rat's movement velocity in such a way that phase interference among their burst pattern creates spatial envelope function which simulate the firing rate maps. | |
