Figure 1

Graphic representation of the average number of TH- positive neurons in the Pe and AVT- positive neurons in the MPA. A) The average total number of tyrosine hydroxylase neuronal cells per containing sections in the periventricular area (Pe) of the hypothalamus (significant main effect of genetic line, see Table 1), and B) the average total number of vasotocin neuronal cells per containing sections in the medial pre-optic area (MPA; significant main effect of rearing, see Table 1). Results presented as average ± SEM; analysis was performed on ranks with a Friedman's Two-way Nonparametric ANOVA. CL NO = control genetic line raised without a hen, CL HEN = control genetic line raised with a hen, LML NO = low mortality genetic line raised without a hen, LML HEN = low mortality genetic line raised with a hen.
