Re: Stubborn Beta at P3 & P4

[Guest guest]

Ok thanks Pete, I'll have to double check my P3 & P4 alpha levels when

I get home from work tonight. I'm pretty sure I have decent alpha back

there EC. I've been away from the board for a few months, I'll

definitely try out the new alpha synchrony design, with active and

reference electrodes on the same side. I'll let you guys know how it's

going after 10 or so sessions.

Thank you

- Steve
