Fig. 3: Progressive transformation of GC firing fields across days.
From: Place cell maps slowly develop via competitive learning and conjunctive coding in the dentate gyrus
a Color-coded, firing rate maps of GCs across days. Only the GCs showing firing fields are displayed for clarity. The rows of the matrices correspond to individual GCs and are sorted according to firing field positions. Top, scheme of the belt. b Color-coded, firing rate maps of GCs on day 1 (left) and on days 13, 16, and 20 combined (right), for each type of GC firing field. The color scale is the same as that used in (a). c Upper, proportion of GCs with a single field (black) and multiple fields (gray) across days. Lower, proportion of LV (light blue), periodic (dark blue) and unspecific GCs (red), among multiple-field GCs, across days. d Upper, definition of LV peak ratio as the ratio between LV fields’ peak firing rates (smaller peak over larger peak). Lower, distribution of LV peak ratios across days. Each dot is the LV peak ratio of one LV cell. Red line, linear fit. n = 53, r = −0.5, p = 1e−4, Pearson’s correlation, two-tailed t test.
