Connectomics, a subspecialty of neuroscience, is the sudy of the brain's 100+ trillion connections, and it's overall organization into networks and subnetworks. It contributes signficantly to our understanding of how brain function affects human experience and how it can lead to mental and physical illness. Unfortunately, clinical psychiatry is 20-30 years behind the neuroscience research in regards to understanding brain function. Modern research into connectomics has offered a refreshing new understanding of mental disorders, teaching us that the brain works both holistically and locally as a series of semi-fluid networks made up of cortical and subcortical regions that have broad and specific functionality. Our past failure to understand this is, in part, why psychiatric and neurological research previously failed to identify consistent brain pathology as well as imaging correlates behind most mental illnesses. Our approaches and methods were, ironically, overly simplistic and reductionistic, leading to incorrect assumptions about how to study mental illness. Past imaging research, for example, failed to reliably identify a single region or set of brain regions that cause schizophrenia. Connectomics research, on the other hand, is now demonstrating that illnesses like schizophrenia and bipolar disorder are largely diseases of various pathologies that alters network connectivity (i.e., they alter the way the brain's networks interact with each other). While connectomics continues to be an emerging science, it has a signficant research base that is over 2 decades old.
