A: motor milestones, B: sensory milestones. Circle: control, cross: control+peptides. Prenatal treatment with the peptides resulted in developmental enhancement of the control pups. The x axes indicate the days of testing and y axis the score from 0 to 1 on the behavior performance, with higher score indicating achievement of the developmental milestone. The milestones that were reached significantly earlier in the control pups treated with NAP+SAL (n=9 from 3 litters) as compared to the controls (n=18 from 6 litters) treated with placebo were righting, vibrissa placing, cliff aversion, screen climbing, ear twitch and weak tactile stimulation (4/5 motor and 2/5 sensory). Each point indicates mean score±s.e.m.
