| Abstract: | Female mice located in utero between two female fetuses exhibited higher levels of locomotor activity in adulthood than did females located between two male fetuses. Male mice, which were less active than females, also were influenced by intrauterine contiguity. Males located in utero between two female fetuses were more active than males which resided between two male fetuses. These results indicate that intrauterine position influences behaviors involved in the maintenance of metabolic homeostasis. |
