This project provides a comprehensive overview of the research literature on the brain and how trauma impacts brain development, structures, and functioning. A basic exploration of childhood trauma is outlined in this project, as it is essential in making associations and connections to brain development. Childhood trauma is processed in the brain; it is responsible for our emotional, cognitive, behavioral, social, and physiological functioning. Understanding how the brain develops, including basic brain structures and functions, as well as how trauma impacts these areas provides the means to better understanding the traumatized child. This project is a comprehensive literature review focusing on the brain and the impact of traumatic experiences on brain development and function. It also includes supportive handouts, which can be used by professionals. (Contains 2 tables, 4 figures, 48 footnotes, and a list of additional resources.)
