Systematic analysis of goal-related movement sequences during maternal behaviour in a female mouse model for Rett syndrome.

Rodent dams seek and gather scattered pups back to the nest (pup retrieval), an essential aspect of maternal care. Systematic analysis of the dynamic sequences of goal-related movements that comprise the entire behavioural sequence, which would be ultimately essential for understanding the underlying neurobiology, is not well-characterized. Here, we present such analysis across 3 days in alloparental female mice (Surrogates or Sur) of two genotypes; Mecp2 (Het), a female mouse model for Rett syndrome and their wild type (WT) siblings.
