Ancestral stress alters maternal behaviour and offspring sensorimotor development. (A) Illustration of a dam carrying her tail during rotations in recordings of postpartum maternal activity. (B) Time spent in tail chasing behaviour during the first hour after completed delivery of her offspring. Note that a history of prenatal stress reduced maternal tail chasing activity. (C) Photograph of offspring performing the inclined plane test on postnatal day 7. Pups were placed head facing down on an inclined plane. (D) Latency to respond with a rotating movement in seven-day old pups. Note that a history of prenatal stress delayed the turning response across generations. Asterisks indicate significances: *P <0.05; ***P <0.001, compared to the respective generational non-stress controls.
