Brain Stress (image) University of Wisconsin-Madison Caption Different forms of early life stress, such as child maltreatment or poverty, impacted the size of two important brain regions: the hippocampus (shown in red) and amygdala (shown in green), according to new University of Wisconsin–Madison research. Children who experienced such stress had small amygdalae and hippocampai, which was related to behavioral problems in these same individuals.
