Stress Can Affect Future Offspring

ScienceDaily (Aug. 23, 2011) — Rats exposed to stress during early development inherit the effects of that stress to their offspring, largely expressed in behavior impairments but also characteristics of resilience, shows a new study from the University of Haifa, published in the journal Developmental Psychobiology.

Providing environmental enrichment to the future mother rats had a remedial role on some of the negative effects. "The similarities between rats and humans raise the question of whether similar effects might transpire in humans; for example, exposure to war or natural disasters might have heritable effects," explains Prof. Micah Leshem who headed the study.
