Electromagnetic fields and Parkinsons

[Laurie Davison]

I am currently studying the effects of dopamine and melatonin on seasonal 
reproductive cyclicity in the mare. In my searches I keep coming accross 
articles involving the use of electromagnetic fields in the treatment of 
Parkinson's Disease. Can anyone out there tell me what physiological 
effect EM has in patients? Specifically, does it tend to 
increase/decrease levels of endogenous dopamine or melatonin and/or does 
it affect sensitivity to these substances? 
    I appreciate your help!

                                      Sincerely,
                                      Laurie Davison
