[00:03:53] Well so there's a couple of things to kind of unpack in there so you are exactly right that we know that children who have been exposed to repeated complex trauma we do see changes in their ongoing brain development and brain chemistry and I am no neuroscientist however we know that for example the simple way to think about it is that those are kids who may have changes as you said in their stress response their reactivity so they may be kids who you know sort of fight or flight in sort of a simplistic way is changed so that they may react in an overexaggerated way or they may also have sort of an inappropriately low response to danger.

This pervasive pattern of stress response system hyporesponsivity is inconsistent with patterns observed in the rodent literature following maternal deprivation (1 ⇓ — 3, 46) and challenges some prevailing conceptual models of early - life adversity and stress response system development, which argue that adverse environments should lead to elevated physiological reactivity (47, 48).

Stress paradigms in rodent models have been associated with elevated anxiety and contrasting alterations in neuronal morphology in the hippocampus and amygdala, with dendritic atrophy observed in the hippocampus and increased dendritic arborization in the amygdala.12, 13 Developing rodents deprived of maternal nurturance show decreased hippocampal volume and altered stress reactivity.14 An epigenetic mechanism for this effect has been elaborated.15 Importantly, controlled trials that have randomized institutionalized toddlers to early therapeutic foster care vs institutionalization have documented the deleterious effects of early relative deprivation on cognitive outcoStress paradigms in rodent models have been associated with elevated anxiety and contrasting alterations in neuronal morphology in the hippocampus and amygdala, with dendritic atrophy observed in the hippocampus and increased dendritic arborization in the amygdala.12, 13 Developing rodents deprived of maternal nurturance show decreased hippocampal volume and altered stress reactivity.14 An epigenetic mechanism for this effect has been elaborated.15 Importantly, controlled trials that have randomized institutionalized toddlers to early therapeutic foster care vs institutionalization have documented the deleterious effects of early relative deprivation on cognitive outcostress reactivity.14 An epigenetic mechanism for this effect has been elaborated.15 Importantly, controlled trials that have randomized institutionalized toddlers to early therapeutic foster care vs institutionalization have documented the deleterious effects of early relative deprivation on cognitive outcomes.16

In humans, both the HPA system and the autonomic nervous system show developmental changes in infancy, with the HPA axis becoming organized between 2 and 6 months of age and the autonomic nervous system demonstrating relative stability by 6 to 12 months of age.63 The HPA axis in particular has been shown to be highly responsive to child - caregiver interactions, with sensitive caregiving programming the HPA axis to become an effective physiological regulator of stress and insensitive caregiving promoting hyperreactive or hyporeactive HPA systems.17 Several animal models as well as human studies also support the connection between caregiver experiences in early postnatal life and alterations of autonomic nervous system balance.63 - 65 Furthermore, children who have a history of sensitive caregiving are more likely to demonstrate optimal affective and behavioral strategies for coping with stress.66, 67 Therefore, children with histories of supportive, sensitive caregiving in early development may be better able to self - regulate their physiological, affective, and behavioral responses to environmental stressors and, consequently, less likely to manifest disturbed HPA and autonomic reactivity that put them at risk for stress - related illnesses such as asthma.
