Elevated plus maze: Data shown are least square means (± SEM) on the EPM during the 5 min test session. A,E: time (s) spent in open arms; B,F: number of open arm entries; C,G: latency to first open arm entry; and D,H: number of open arm head dips. Group A was tested on P57 and Group B on P122. Group sizes for Group A: Number of litters tested = 21; data are based on the following number of subjects/group: Control = 20, Flu3 = 20, Flu10 = 20, Par3 = 20, Par10 = 20, Par17 = 20. One litter's data were missing because of a DVD playback defect. For Group B: Number of litters tested = 20; data are based on the following number of subjects/group: Control = 16, Flu3 = 16, Flu10 = 16, Par3 = 16, Par10 = 16, Par17 = 16. Data were unrecoverable from 4 litters whose recorded data tracks would not playback from the DVD.
