Neuroimaging: Brain Networks and Connectivity

Neuroimaging is a branch of medical imaging that employs imaging technology to investigate the anatomy and function of the nervous system in a non-invasive manner. With the help of neuroimaging, the doctors and researchers can explore how the CNS, more specifically, the brain function is affected in states of health and disease. Conditions such as stroke and head injury may affect the normal brain functions related to cognition and information processing. Neuroimaging studies two major aspects of the brain. First, neuroimaging studies how the brain and the brain network works. Second, neuroimaging studies how different activities affect the brain. The essential tasks for neuroimaging are the refinement of preoperative differential diagnosis, precise anatomical localization for operational planning, detection of response to therapy, detection of tumor development, and recognition of treatment-related adverse effects. Major neuroimaging techniques include, computed tomography scan (CT), magnetic resonance imaging (MRI), positron emission tomography scan (PET), and diffusion tensor imaging (DTI). This book discusses the fundamentals as well as the recent developments in the field of neuroimaging. It presents researches and studies on brain networks and connectivity performed by experts across the globe. This book is a resource guide for experts as well as students.
