Effects of stress on retention performance in a water maze task

(A) All stress groups spent less time in the target quadrant and spent more time in the opposite quadrant compared to the control group (B) The Average proximity (C) The platform location latency (D) The number of crossings in the area of the original location of the platform. Stress impaired memory retention, as evidenced by the fact that the stressed rats had significantly larger proximity values, more platform location latency, and lower number of crossings compared to the control group. Data are expressed as mean±SEM
