    • The mean number of pretraining days in the test environment was 17 (square-circle), 14 (two rooms), and 4 (black-white).

    • The rate threshold was 0.27 Hz. Similar results were obtained with rate thresholds of 0.10 Hz and 0.50 Hz (tables 51 and 52) (23).

    • If the external spatial input is strong enough, it is theoretically possible for large changes to occur in the firing rates of some cells, whereas intrinsic attractor dynamics of the network maintain the relative relations between the place fields of the ensemble (35).

    • In these studies, which all focused on CA1, much of the residual activity in the less active condition appeared inside the cell's place field in the more active condition [e.g., figure 8 in (30), figures 3 to 5 in (14), figures 2 to 6 in (15), figure 6 in (16), figures 6B and 9 in (12), and figure 4 in (13)], as expected if the remapping was primarily rate-based. In (30), 70% of the cells exhibited peak activity in the same quadrant in the two directions.
