In this episode, we discuss how the B-SNIP project is working to utilize biomarkers to redefine categories of psychosis across schizophrenia, schizoaffective disorder, and bipolar disorder. We do our best to break down complicated math into digestible chunks to figure out how the authors go from collecting things like eye movements and EEG responses to sound in order to create a new way of classifying patients with psychosis. We end on the most important question--why should a practicing psychiatrist care about this anyway?
