More research is needed regarding how specific ELS experiences influence specific aspects of neurodevelopment. Hanson JL, Knodt AR, Brigidi BD, Hariri AR. Neuroscience has greatly illuminated our understanding of how both positive and negative early life experiences affect brain development, with implications for childrens mental and physical health. Social vocalizations can release oxytocin in humans. Additionally, these circuits are implicated in emotion processing, self-regulation, and memory and learning [76,77,78]. Recent evidence suggests that early life stress also has a range of negative effects on dopaminergic circuits involved in motivation, specifically those related to reward processing [138, 139]. Marusak HA, Hatfield JR, Thomason ME, Rabinak CA. Longitudinal work suggests that children exposed to various forms of early life stress demonstrate an atypical trajectory of age-related changes in PFCamygdala connectivity as compared to peers who were not exposed to early life stress [51].

Based on this evidence, specific models assume that different types of stressors will have distinct and separable effects on developing neural systems. Specifically, children who experienced maltreatment demonstrate decreased striatal, orbitofrontal cortex, and hippocampal activation during reward learning [157], and children with high early life stress demonstrate decreased activation of the putamen and insula when anticipating future losses [138].
