Location of ventromedial prefrontal cortex (red) and right amygdala (green). We utilize mobile sensing data to predict the brain connectivity between these regions, as the functional connectivity between vmPFC and amygdala is known to be associated with various aspects of mental health. The Montreal Neurological Institute coordinates are (8, 36, −18) and (20, −3, −15) for the right vmPFC and amygdala, respectively.
