Title: What the Brain's Spontaneous Activity Can Tell Us About Psychiatric Symptoms - Spatiotemporal Psychopathology
Presenter: MiNDS Program Presentation - Georg Northoff
Date: February 7, 2018 / 9-10 am, West 5th site, Lower Auditorium
Dr. George Northoff, Philosopher, Neuroscientist and Psychiatrist, Canada Research Chair in Mind, Brain Imaging, and Neuroethics, ELJB-CIHR Michael Smith Chair in Neurosciences and Mental Health, Research Unit Director.
Co-Sponsored by McMaster Integrative Neuroscience Discovery & Study (MiNDS) Program
After Dr. Northoff’s presentation a post talk meet and greet took place, which was open to all attendees.
The brain's spontaneous activity has been extensively investigated in recent years in various psychiatric disorders. However, its exact meaning and diagnostic relevance remains unclear. I here present various measures of the brain's spontaneous activity going far beyond the usually investigated functional connectivity; these measures include regional homogeneity, scale-free activity, and neuronal variability. I show the relevance of these measures for both mental features like self and their abnormalities in psychiatric disorders like schizophrenia and bipolar disorders. I conclude that the abnormal changes in the temporal and spatial features of the brain's spontaneous activity transform into abnormal spatiotemporal organization of mental features - therefore, I speak of "Spatiotemporal Psychopathology".
