Effects of reproductive experience on working memory in middle-aged nulliparous (n = 9, dashed lines) and primiparous (n = 8, continuous lines) female rats when the ITI was 10 min (ITI 10) or 60 min (ITI 60). (A) Latency to find platform (s). (B) Path length (cm). (C) Swim speed (cm/s). (D) Number of entries into the previous day's critical counter. (E) Percentage of time spent within the quadrant in which the platform was located on the previous day. (F) Percentage of time spent within the inner ring. (G) Percentage of time spent within the intermediate ring. (H) Percentage of time spent within the outer ring. (I) Percentage of time spent within the previous day's critical counter. Data are expressed as mean ± SEM for the trials across days 1 through 8 (ITI 10) and days 9 through 13 (ITI 60).
