Effect of Long-Term Sodium Salicylate Administration on Learning, Memory, and Neurogenesis in the Rat Hippocampus

Figure 4

NaSal administration impaired the expression of delta-FosB during spatial memory retrieval. (a) Representative immunohistochemical staining of delta-FosB-positive cells in the hippocampal CA1 region from NaSal-treated and control rats. (b) Contrasting expression of delta-FosB during the retrieval of the spatial memory in NaSal-treated and control rats. Independent-samples -tests revealed that NaSal treatment showed a significant decrease on the day of the probe test in the rats treated for 7 [ (15) = 3.521, ] and 14 [ (15) = 5.859, ] days. –10, mean ± SEM, , .
