Figure 2.

Effect of learning on late-component occurrence rate. (A) Occurrence rate (measured as described in Materials and Methods) was compared between control (n = 7) and trained (n = 11) groups after learning. (*) P ≤ 0.05 (χ2 comparisons): significant difference between trained and control animals in the corresponding recording site. (B) Occurrence rate was compared between the different recording sites either before or after learning in animals of the trained group (n = 11). (*) P < 0.025, (**) P < 0.005 (Fisher's test): significant difference with the anterior piriform cortex (aPC) and the dentate gyrus (DG) measured after learning. (•) P < 0.005 (Fisher's test): significant difference with aPC and DG measured before learning.
