Deanna Barch is a professor of psychology, radiology, and psychiatry at Washington University. Deanna is a key contributor to the Human connectome project, which aims to build a network map of the anatomical and functional connectivity within the healthy human brain, as well as to produce a body of data that will facilitate research into brain disorders such as dyslexia, autism, Alzheimer's disease, and schizophrenia. We discuss what is known about the way that our brain are connected, and the impact of stress and trauma on brain development.
