Figure 2.

FCbP median split shows that only half of FCbP rats displayed freezing behavior when tested 24 h after the FCbP training session. The upper half of the FCbP rats (FCbP+) froze more than the lower half (FCbP-) of the FCbP and the naïve control rats (p<.05). Fear-conditioned rats froze significantly (p < 0.05) more than either FCbP or naïve rats.
