Hi,
I agree, i had to formulate my question in an other way.
The is point more about the "location" for electrode placement.
My one-chanel-waverider comes with only poor infor-
mation about electrode placement. In fact there docu-
mentation only shows placement on the forehead.
There are three exercises. 1. Focus, one must try to
concentrate on al line and to raise it. I guess this would
train smr (low beta). 2.Chill, when you relax music be-
gins to play. I guess this would activate alpha.
3. Listen, tunes in the present moment, quieting the
chatter of your mind. i don't know exactly what this means. (innate abilityto be attentive). Would be very nice
if one could stop mind chatter, i mean stopping thougts.
(i don't know however wheter this can be done with NFB)
In all the exercises the electrode is placed al little bit
higher on the forehead.
Question is then: would this be effective training to deal
with depression or anxiety ?. If afther some sessions i
would be alble to control the programs i would thus be
alble to change my brainwaves.
Out of curiousity i would like to place the electrode on
a different place so as to influence different parts of the
brain. The use of a one channel EEG result mostly in the
placement of the electrode on the forehead.
However (appart from low beta), would there be im-
portant information on the forehead ?. Would activating
or lowering brainwaves from the forehead result in less
more depression/anxity ?.
Regards Frans

Frans--Your question seems to presume that the answer to both anxiety
and depression is to "relax the right brain." This is a logical
assumption and I can understand why one would think of it this way,
but this is not necessarily the best approach based on clinical
experience. Training alpha-theta activity at the left occiput is
often all you need to do to reduce both anxiety and depression (see a
paper by Saxby and Peniston about 1995; I don't have the exact
reference immediately at hand). Or training alpha at Pz may replace
both anxiety and depressive ideation with a relaxed, focused state.
Or training beta at F3 or T3 may eliminate depression and induce a
rather euphoric state. Now I'll bet that other clinicians have other
ideas, will have discovered other things that work, and will advocate
for their specific approaches. And their methods will probably work
about as well as mine. Sometimes I think it's not so much the
specific training protocol that matters, but rather just the process
of using neurofeedback to get the mind/brain system out of a rut it's
stuck in. It's hard to adjust to this idea, but all sorts of
different approaches seem to get results.
