Biological psychopathology
Biological psychopathology is the study of the biological etiology of mental illnesses with a particular emphasis on the genetic and neurophysiological basis of clinical psychology. Biological psychopathology attempts to explain psychiatric disorders using multiple levels of analysis from the genome to brain functioning to behavior. Although closely related to clinical psychology, it is fundamentally an interdisciplinary approach that attempts to synthesize methods across fields such as neuroscience, psychopharmacology, biochemistry, genetics, and physiology. It is known by several alternative names, including "clinical neuroscience" and "experimental psychopathology." Due to the focus on biological processes of the central and peripheral nervous systems, biological psychopathology has been important in developing new biologically-based treatments for mental disorders. Scope Biological psychopathology is a field that focuses mostly on the research and understanding the biological basis of major mental disorders such as bipolar and unipolar affective disorder, schizophrenia and Alzheimer's disease. Much of the understanding thus far has come from neuroimaging techniques such as radiotracer positron emission tomography(PET), and functional magnetic resonance imaging (fMRI) scans, as well as genetic studies. Together, neuroimaging with multimodal PET/fMRI, and pharmacological investigations are revealing how the differences in behaviorally relevant brain activations can arise from underlying variations in certain brain signaling
