Table 4.

Mean firing field size for each of the four lap types and mean percentage of the trajectory covered by the field

Lap type	Mean field size (cm)	Percentage of trajectory (total length was 155 cm for sample laps and 280 cm for choice laps)a
Left sample laps	138.57 ± 29.62	86%
Right sample laps	134.51 ± 51.26	89%
Left choice laps	134.51 ± 51.26	48%
Right choice laps	140.71 ± 38.75	51%

^aNote that choice lap trajectories were longer than sample lap trajectories because choice laps included the return arm bins.
