c-Fos expression in basolateral complex (BLC), central (CeA), cortical
(CoA), and medial (MeA) amygdalar nuclei in control and experimental groups of
rats. The data represent the average number of c-Fos immunostained cells of
left and right nuclei except the handled group, where the data from right
(Handled) and left (Handled_Vehicle) nuclei were presented separately. (*)
Significant differences between right and left (vehicle-injected) sides in
group of handled rats; (#) significant differences from naive rats; (+)
significant differences from Trained-Vehicle group, p < 0.05 in
each case (Newman-Keuls post hoc tests; see text for results of ANOVAs).
