Top panels: male mice. Top left: Self-directed grooming behavior in the three-chamber test. Grooming was elevated by MIA treatment, and this effect was reversed completely by KD feeding. Post hoc tests were restricted to within-phase comparisons; n = 8–10. Top right: Self-directed behavior in the single chamber test. Grooming was elevated by MIA treatment, and this effect was partially reversed by KD feeding. **p<0.01, ***p<0.001 compared to CD-fed control offspring. ##p<0.01 compared to CD-fed MIA mice; n = 8–10. Bottom panels: female mice. Bottom left: Grooming in the three-chamber test was not elevated by MIA treatment in females; it was, however, lowered by KD feeding; n = 11–12. Bottom right: Grooming in the one-chamber test was not affected by MIA or KD in females. *p<0.05, ***p<0.001 compared to CD-fed control mice.
