Effect of chronic ECS on TrkA immunoreactivity in the CA2 (A – B), and in the CA3 subfields of the hippocampus (C – D). Representative photographs illustrate TrkA immunoreactivity in sham treated control animals (A and C), and at 24 hr (B and D) after chronic ECS treatment. Histograms show the mean values (for each groups of animals; n=6) of the number of TrkA immunopositive cell processes after chronic ECS (solid bars), as compared to control (sham ECS) group (open bars). Asterisks indicate significant difference (*P<0.05 ; **P<0.01; ***P<0.001; ANOVA with Fisher’s test) from control group. The black boxes in the schematic brain section illustrate the areas from which the photographs and measurements were taken. Photographs were acquired at 10x (A – D) and 40x magnification (A’ – D’).
