Electromagnetic fields and Parkinsons

[Laurie Davison]

Thorsten,
     Thanks for getting back to me. To be honest, I don't know enough 
about EM fields to specify. I came accross references to the treatment of 
Parkinsons while running a lit search on dopamine and it made me begin 
asking questions in my mind... I am investigating the inhibition of GnRH 
secretion during seasonal anestrous in mares. Dopamine is thought to be 
one of the many inhibiting factors, as is photoperiod (thus my wondering 
about EM's and melatonin). Specifically, I suppose I would be interested 
in knowing precisely *what* frequencies, intensities, etc, are enough to 
cause an increase in either the production, secretion, or sensitivity of 
the hypothalamus to either DOP or melatonin. As little as I know (being 
an endocrinologist and not a neurobiologist), I would appreciate anything 
I can learn on this subject. 
      I appreciate your time!
