Differences in Visual-Spatial Input May Underlie Different Compression Properties of Firing Fields for Grid Cell Modules in Medial Entorhinal Cortex
Fig 3
Shows the compression in configuration B compared to configuration A.
(A) Simulated grid cell firing pattern from a simulated dorsal entorhinal cell for (A) configuration A (grid score 1.88) and (B) for configuration B (grid score 1.91). (C) Correlation values for different magnitudes of compression of B relative to A shows a peak correlation at a compression of ≈ 3.1%. (D) The simulated grid cell firing pattern from the ventral entorhinal cell for (D) configuration A (grid score 1.66) and (E) configuration B (grid score 1.25) based on inaccurately estimated locations in Fig 2F. (F) Correlation value for different magnitudes of compression of configuration B relative to configuration A shows that the grid cell firing in configuration B needs to be increased by a compression factor of ≈ 95.5% (about 50 cm) to obtain maximum correlation with the grid cell firing pattern from configuration A.
