CNE_23251_sm_SuppFig1.tif3103KSupporting Figure S1. Retrieval latencies of female mice from which the c-Fos IHC was obtained. Data are shown as mean ± S.E.M. All mice from the Virgin with pups group (n = 18), OxtrVenus/+ (n = 3) and Postpartum group (n = 6) retrieved all pups within 30 min. Asterisks: significantly different from the other two groups (P < 0.05). A, latency for first pup; B, latency for second pup; C, latency for last pup.
