Document Summary
Early life experiences program our stress set point. Stress set point = baseline stress level, and how your system responds to a stressful environment. Epigenetics: on top of genetics, relates to the environmental impact on our genes. Epigenetics: stress can cause external modifications to dna that turn genes on or off , these modifications do not change the dna sequence, but instead, they affect how cells read genes. Material care behaviours programs adult stress response in rats. Stress set point is largely influenced by our experience of stress early in our lives. Difficult to manipulate stress in human infants so you look at rats. Hlg: high licking and grooming (positive: pups turn out to be less stressed adult rats. Llg: low licking and grooming (negative: pups turn into more stressed adult rats. Result was a famine very little food in the netherlands, people"s daily caloric intake went from.
