Home built EEG

I am building an EEG machine and intend to digitize the amplified analog signals for input into a 
computer.  I am considering using a 16 bit A/D for each channel.  The question I have is: Is a 16 
bit A/D overkill?  Is 12 bits sufficient.  What kind of voltage range am I liable to encounter on 
the EEG electrodes?  I intend to use isolation devices between the front-end 
processor and the main computer.

Any advice would be appreciated.
