Fig. 4.  Performance in the elevated plus maze. Adult rats exposed to isoflurane in utero  (n = 13) made more open arm entries (P = 0.005, significant after Benjamini-Hochberg correction; A ), though there were no differences in the time spent in the open arms (P = 0.02, not significant; B ), compared to controls (n = 11). Data are expressed as mean ± SEM.
