Figure 4:Comparison of the effect of nimodipine on Fos expression in DCN. (A-D) The effect of nimodipine on Fos expression in DCN is compared to the data obtained from the untreated animals for each experimental setup: after dummy implantation of the electrode carrier (A) as well as following EIS at 1.6 Hz (B), 50 Hz (C) and 400 Hz (D). It is differentiated for both sides of DCN into the three analyzed layers. (***): p<0.001; (**): p<0.01; (*): p<0.05; Co: Control group; fusi: fusiform layer; deep: deep layer; vertical: vertical cell layer; nimo: nimodipine-treated group; i: ipsilateral; c: contralateral.
