The total number of 31 Wistar rats has been divided into six different experimental groups. Controls were run without (group 1) and with nimodipine (group 2). Group 3 (no nimodipine) and group 4 (with nimodipine) underwent a 2 h dummy implantation of the electrode carrier. EIS was being performed without (group 5) and in combination with nimodipine (group 6). Within the two EIS groups, three animals were used for each setup of stimulation (1.6, 50, 400 Hz).
