a Time needed to find the hidden platform 5 weeks after cardiac arrest in 8 min (min) cardiac arrest (CA) study group (n = 9); control, untreated control group (n = 10). Mean time ± SEM in seconds (sec) to find the hidden platform in this first Morris Water Maze paradigm with 3 trials (maximum time 120 s) daily (a, b, c) on 4 consecutive days (1–4). b and c Probe trial 24 h (b) and 7 days (c) after the last trial; mean time in seconds ± SEM (p values target sector vs each other quadrant * p < 0.05, n.s. not significant). TS target sector = SE south east sector, NW north west sector, NE north east sector, SW south west sector
