Fig. 2: Types of place field activity among GCs.
From: Place cell maps slowly develop via competitive learning and conjunctive coding in the dentate gyrus
a Scheme of the treadmill showing the 3 pairs of landmarks fixed on the belt. b Individual cell examples for various types of GC representations: a single-field cell; a landmark-vector (LV) cell (showing two fields matching a type of landmark); a periodic cell (with three periodic fields); and an unspecific cell (with more than one field that are neither LV nor periodic). Top, scheme of the belt; middle, spike raster and color-coded firing rate map; bottom, mean firing rate. c Color-coded, firing rate maps of GCs from all sessions, sorted according to field positions and grouped by type of representation. Line plots, average of firing rate maps for each type of representation (lines, the mean; shadows, s.e.m; n = 178 single, 105 unspecific, 53 LV and 11 periodic cells). The color scale is the same as that used in (b).
