Nest building performance and nest complexity. The assessment of nest building performance during the 4-day observation period showed that in prepubescent (A) and sexually mature mice (B) mice, a significant effect of genotype on nest complexity scores was detected for several of the four observation days. Genotype significantly interacted with sex, reflecting decreased nest scores in female Gria1^–/– mice when compared to female wild-type littermates on the first day in prepubescent mice (A) and on the second day in sexually mature mice (B). The analysis of nest complexity sum scores revealed significantly decreased scores in prepubescent (C) and sexually mature (D) Gria1^–/– mice as compared to wild-type littermates. ART ANOVA, followed by FDR correction or Bonferroni multiple comparison post hoc tests. n = 4–5 per genotype per sex. *p < 0.05 and #p < 0.05 (females). (A,B) Illustrate the median, in (C,D) error bars indicate the standard error of the mean (SEM).
