Effect of ECS on NGF and TrkA immunoreactivity in the amygdala. A–B: Representative photographs of NGF immunoreactivity in (A) sham treated control animals, and (B) at 24 hr after chronic ECS treatment; C–D: Representative photographs of TrkA immunoreactivity in (C) sham treated control animals and (D) at 7 hr after chronic ECS treatment. Histograms show the mean values (for each groups of animals; n=6) of the number of NGF or TrkA immunopositive cells after acute (striped bars) or chronic ECS (solid bars), as compared to control (sham ECS) group (open bars). Asterisks indicate significant difference (*P<0.05 ; **P<0.01; ANOVA with Fisher’s test) from control group. A black box in the schematic brain section illustrates the area from which the photographs and measurements were taken. Photographs were acquired at 10x (A – D) and 40x magnification (A’ – D’).
