Besides the environment and caregiving, can intergenerational trauma be transmitted genetically? This week we discuss the research that has been conducted in mice to better understand where biology fits in the context of trauma. From epigenetic and behavioural changes in traumatised parents, to what was observed in their offspring and future generations. Make sure you listen to the end, where we go through preliminary evidence on healing from trauma with enriched environments and positive life experiences.

TLDR: Studies in mice showed that trauma-induced epigenetics changes that alter behaviour are inherited in offspring
