Spatial memory formed in the Morris water maze under different stress conditions, warm (24 ± 1°C) and cold (19 ± 1°C) water, when interfered by a foot shock stress. (A) Mean escape latencies during the 4 final trials of initial training did not differ between WW and CW animals; (B) The foot shock interference procedure impaired memory retention as tested on day 3 (during relearning) in CW animals, but not in WW animals; (C) The mean escape latency of the cold water animals following interference during the first trial was significantly longer than that of the cold water group that experienced no interference (*p < 0.05). (CW, Cold water; WW, Warm Water; CW_I, Cold Water with interference; WW_I, Warm Water with interference).
