The Ego, Prediction Error, and the Default Mode Network
October 17, 8:00 pm - 9:30 pm
Presenter: Burns Woodward, M.D.
Freud believed the ego works to minimize free, or unbound, psychic energy, a process that some neuroscientists have related to the brain’s efforts to minimize prediction error. The brain constantly anticipates perceptions, events, and actions. Measures of the accuracy of these predictions can be derived from the activity of brain networks. The default mode network is thought to function something like the ego in minimizing errors in this prediction process. We will explore possible applications of these ideas to understanding patients’ mental status and to disorders such as depression, addiction, and obsessive-compulsive disorder.
