That was very very astute of you zerge... there are it seems 
though EMF emmissions from the brain at the quantum level, but 
only when many neurons fire at the same wave length at the 
same time...such as with sudden cognition or surprise etc..

the search string for Dr Penroses research on that with the 
math etc  is.
'penrose, Arizona, quantum mind, white paper'
