Figure 2

Cellular-resolution imaging of MEC grid cells. A. Field of layer 2 MEC neurons labeled with GCaMP-6f and imaged through MEC microprism with two-photon microscopy. B. GCaMP-6f ΔF/F versus linear track position traces for 10 grid cells shown in Figure 2A. Each of the 22 track traversals is shown for each of the 10 cells (bottom, significant transients highlighted in red) along with the mean of ΔF/F versus track position for all traversals (top), this mean trace is referred to as the mean track firing pattern. Significant grid fields highlighted in green. C. Mean of ΔF/F versus track position for all other grid cells shown in Figure 2A. D. Grid fields per meter and field width for all 259 grid cells (mean ± STD). E. Histograms of number of grid fields (left) and field widths (right) for all grid cells. F. Field width decreases with increasing fields per meter (n = 259 grid cells, P < 0.01 Spearman Rank Correlation Coefficient).
