5-HT2CR mutant mice exhibit altered syntactic grooming chains. A, Increased duration of phase 3 and decreased duration of phase 4 syntactic grooming in 5-HT2CR mutant mice. Mean phase 3 duration was 29.8 ± 2.2 s in wild-type mice, 39.8 ± 5 s in 5-HT2CR mutant mice (p < 0.05); mean phase 4 duration was 239.2 ± 17.9 s in wild-type mice, 192.0 ± 14.2 s in 5-HT2CR mutant mice (p < 0.03). B, Alteration of nonsyntactic grooming properties in 5-HT2CR mutant mice. 5-HT2CR mutant mice exhibit increased nonsyntactic grooming event initiation (5.20 ± 0.4 grooming events per minute vs 4.07 ± 0.16 in wild types; p < 0.015) and reduced nonsyntactic grooming duration (1.89 ± 0.1 vs 2.55 ± 0.11 s in wild types, p < 0.0007). Data are represented as mean ± SEM. n = 8 per genotype. *p < 0.05; **p < 0.001.
