n this episode Dr Dunkley discusses in detail the neurophysiological brain changes associated with psychological trauma. He describes fascinating studies looking at the brains of people with post-traumatic stress disorder (PTSD), and explains findings that may underline symptoms such as feeling stuck with looping memories, thoughts, flashbacks, and emotional triggers. Dr Benjamin Dunkley works at SickKids Hospital in Toronto as an MEG Clinical Associate, using MEG (magnetoencephalography) to study how different neurological and psychiatric conditions affect brain function. He earned his PhD at Cardiff University in the UK, and his postdoc at York University, Toronto, followed by a second postdoc at The Hospital for Sick Children in Toronto with Drs. Margot Taylor and Elizabeth Pang. He has authored dozens of scientific publications, and his laboratory work has been referenced on the CBC, The Globe and Mail, National Geographic, and The Economist.
