The default mode network (DMN) typically comprises the posterior cingulate cortex (PCC), precurnus, inferior parietal, hippocampus and medial prefrontal cortex (MPFC) nodes. These regions are commonly reported more active during rest or during a task with little cognitive demand. DMN is active when individuals are engaged in internally focused tasks including autobiographical memory retrieval, envisioning the future and conceiving the perspectives of others. This book examines the importance of DMN in evaluating brain development, neurological and neurodevelopmental disorders. The authors’ also review how DMN is disrupted in neuropsychiatric disorders in relation to cognitive-behavior dysfunctions, such as attention and memory (for example, with ADHD) and explores the connectivity between DMN’s nodes, which change with age and may continue changing into adulthood.
