Left column of each panel: correlation of interval rate maps for cumulative 1-min blocks in AB vs. the corresponding rate map for the entire trial in either A|B (light red line) or AB (dark red line). Only the central half of the environment is included in the correlation analysis (center half of A, center half of B; together they covered 200 cm x 100 cm of the box). Time intervals increased cumulatively by 60s (block 1 is for 0–1 min, block 2 for 0–2 min, block 3 for 0–3 min, etc). Rat number and cell identity are indicated at the top (T = tetrode, C = cell). Right column: same as to the left but for the distal half of A|B (light grey line) or AB (dark grey line). Also here the distal half of A and distal half of B covered together 200 cm x 100 cm.
