This slide should have been on the front page of the Science Times. Top of the slide shows the connectivity pattern as seen on fMRI between the periaqueductal gray (PAG) and the amygdala in 100% of study subjects experiencing dissociation. The PAG is a brain stem/midbrain reptilian structure that acts primarily as a threat detector. The Lanius research suggests that the PAG fires first setting off the amygdala and that this connection is hyper wired in those with histories of neglect and abuse in early childhood. All of this makes intuitive sense.
The bottom half of the slide shows a dramatic change in functional connectivity after one neurofeedback session, in this case alpha-down (8-12) at PZ. This second set of fMRI images were taken fifteen minutes after training, the period of time that assures that the brain has remembered. There has been long term potentiation (LTP) or learning in 80% of subjects.
This article from Scientific American presents a pretty clear description of the importance of optimal connectivity- hubs, nodes, modules and edges and argues a bit for understanding mental illness in terms of malfunctioning connectivity. Except for the glaring paradigm blindness - they look right through what they are seeing and the possibility of reaching it with feedback- it fits nicely with all that Rob has been teaching. ...
