EMG of the Face!!

[Rodrigo Licio Ortolan]

Dear All
I am starting to work with ocular EMG. I need geting the signal of
eye's movement with superficial EMG. The problem is: this muscle aren't
superficial.
I tried to obtain these signals with a Single Differential Surface EMG
Electrode like Delsy's Electrode (http://www.delsys.com/) but I didn't
have result. I just obtained signs, of the orbicular of the eye, when the
volunteer blinked.

How can I get these signals??

Thank's a lot
