I have just started using my Sota MP and use it on an area of my face. Regarding the brain I do have some information which comes from the book, The Invisible Force by Fred Rinker which states Brain Circulation using PMK (pulsed magnetic frequency - I think!) as an optional treatment to increase circulation to the brain. A bipolar magnetic necklace can also be used. But he has not mentioned much on using other forms of the magnets here. He suggests U could sleep on a North Pole magnetic pillow as he states refer to Dr. William Philpott's book on 'Brain Allergies'. Fred Rinker's book does not mention parasites at all and neither how to apply the magnetic pulser to the brain area for that purpose. I have read on the Toolsforhealing site and another one that the magnetic pulser does kill pathogens, i.e. parasites but I still, like u, need to search some more on this.
