Neuroimaging and psychiatry
Professor Wayne Drevets discusses the impact of neuroimaging on psychiatry - allowing clinicians to look at brain function or brain chemistry in patients.
Researchers use neuroimaging in part because it gives you a non-invasive way to look at humans or non-human primates or other types of animals in a way that doesnâ€™t hurt the individual. You can look at the living brain in a non-invasive way using brain imaging. In psychiatry that has been indispensable, because we havenâ€™t had a way to look at brain function or brain chemistry in individuals who suffered from psychiatric disorders. We also donâ€™t have animal models that really faithfully represent all of the different changes that occur in associating with schizophrenia or bipolar disorder or other psychiatric illnesses. So brain imaging has become a primary tool to research the pathophysiology of psychiatric disorders within the context of studying illnesses where we didnâ€™t previously have tools where we could look at structure and function in living patients who suffer from the illnesses we study.
