Hi Dan,
Thanks for the articles.  The real issue has been the connection between potential receptors and neural processing.  The latest research has found neural correlates.  Next will be ablation studies, if brain cells are destroyed retrograde degeneration of the nerves occurs which will in theory allow folks to track down the actual receptors.  The articles you've brought to attention here reflect the detection of possible receptors as well as speculations about them.  All worthwhile theories and hypotheses.  This one picks up on the other end with working neural processing that likely underlies behaviors.  You're very right to indicate that the presence of magnetic particles in particular areas.  It has been known for a while.  The difference is the processing.
