Today our guest is Nathan Spreng. Dr. Spreng is the James McGill Professor of Neurology and Neurosurgery and Director of the Laboratory of Brain and Cognition at the Montreal Neurological Institute and Hospital at McGill University.

As an undergraduate, Dr. Spreng was initially interested in pursuing a major in poetry until he took a psychology class that sparked his interest in the brain. He received Ph.D. in 2008 from the University of Toronto in Brian Levine's lab, and post docs with Cheryl Grady at the University of Toronto and Dan Schacter at Harvard. After about 5 years as an assistant professor at Cornell University, he moved to McGill University.

Throughout his career Dr. Spreng has been using fMRI to reveal subtle yet repeatable large-scale brain networks as they relate attention, memory, cognitive control, and social cognition. He has also helped to elucidate the central role that the default network plays in self-generated thought, and in how it dynamically interacts with multiple systems in the brain.

In this episode Peter and Nathan have a far reaching conversation about his work and what it implies, covering his study of age dependence of resting state hippocampal-linked network ensembles, how to move from mapping networks to modeling and understanding mechanisms, the many possible clinical implications of his work, current understanding of Alzheimer's disease, our mutual appreciation for multi-echo EPI, his data release paper of a large multi-echo EPI and structural MRI data set, and much more.

Enjoy listening!
