on shuttlebox-escape performance and elevated plus-maze behavior. It was concluded that neonatal androgens can affect open-field behavior and maze performance and argued that these sexually dimorphic behaviors probably do not require circulating androgens for their expression. In our laboratory, a video-tracking system(e.g., Any-Maze, purchased from Stoelting). Ninety-day old testosterone-treated females learned a Lashley III maze with significantly fewer errors and retracings than did normal females in this respect the treated females resembled the normal males.

The maze performance of animals from Experiment 2 was also studied. Y maze novel arm test - The ability to discriminate similar contexts and explore a new environment was tested in a Y maze. In Experiment 2, at both 30 and 70 days of age, normal females defecated significantly less often than either the males or the treated females. A similar but statistically nonsignificant effect was observed in the second test conducted at 70 days of age (adulthood). In both Experiment 1 (n = 54) and Experiment II (n = 47), the treated females behaved like normal males at 30 days of age (prepubesence), showing significantly lower ambulation scores than the normal females. Detour maze solvers versus non-solvers also show equal distributions across the sexes (b). In two experiments open-field behavior of female rats injected neonatally with testosterone propionate was compared to that of normal, oil-injected male and female littermates. median performance of 60 for any of the 3 test ratios (7:14, 8 vs 12, 9 vs 12)) (a).
