Of course it would be better to have access to everything from 0.5Hz
up, and delta and theta inhibition are good things to do in treating
ADD. But isn't most theta activity actually at or above 5 Hz? Do
you think there would be no Tx effect for suppressing, say, 5-11Hz
and reinforcing 12-16 (or whatever)? Lots of people have been
successfully treated with no attention to delta whatever.

Good--I'd really rather not settle for a 5Hz floor, but was trying to
suggest that even trhis limitation would not render the device
worthless.

How about something like a Budzynski Twilight Learner? I always
wanted to play with one but couldn't imagine spending $3000 or more
to buy it. BTW--any idea how many of these things Tom B. has sold
over the years? They've been around in one or another version since
the late '70s or so, I think. Maybe even early '70s.
