Hope and uncertainty about outcomes

Toronto journalist Anna Mehler Paperny had experimental surgery that placed electrodes in her brain in the exact location neurologists believe could be the source of her depression. She's part of a clinical study out of Sunnybrook Health Sciences Centre that uses deep brain stimulation to treat mood disorders. She speaks about the procedure and her hopes that the study, a first of its kind in Canada — will lead to a better understanding of the physiology of depression and its treatment.
