(A) Distribution of EMD scores, selecting the lowest value on any of the four templates for each MEC neuron. Dark green represents the population of border cells in MEC that were classified previously using the border score. (B) The four templates used in this procedure, with firing fields attached to a single wall. (C) Spatial rate maps of 8 cells with the lowest EMD score on any of the templates (e.g., most left values in A). Top row: two examples of cells with localized firing nearby the wall, which resulted in a low EMD score. Middle row: three examples of cells not classified by the border score (e.g. values below 0.5), but still rather border-like. Bottom-row: three border cells identified by both methods.
