English: Firing of a boundary cell recorded in rat subiculum in 1 x 1 metre square-walled box with 50cm-high walls. A 50cm-long barrier inserted into box elicits second field along north side of barrier in addition to original field along south wall.

Left: Firing rate map, one of 5 colours in locational bin indicates spatially-smoothed firing rate in that bin (autoscaled to firing rate peak, dark blue: 0-20%; light blue: 20-40%; green: 40-60%; yellow: 60-80%; red: 80-100%. The maximum firing rate is 14.2 Hz). Right: path taken by rat is shown in black, locations where spikes were recorded indicated by green squares.
