Electrode placement for alpha synchrony

[Guest guest]

Listmates,

What's the best placement for the electrodes in a two-channel alpha synchrony design? I'm getting lots of beeping (synchrony? Artifact?) using C3 and C4, with Cz as ground and the ears as references. Should the actives be farther apart? I don't want to be at the temporals but I want a nice wide area. Thanks'

I think that most people who are doing alpha synchrony training are using sites

in the parietal and/or occipital lobes, given that those are the sites that

produce the greatest alpha response.

Since synchrony is distance related, the further apart two sites are, the harder it is for them to respond at the same time.  Sites like T3/T4, T5/T6 and F7/F8 are not generally as synchronous as F3/F4, C3/C4, P3/P4, etc.  O1/O2 are very close together and pretty easy to get synchronous.

Pete, thanks. I'm getting constant tones on-off-on-off (well not really constant - irregular pattern) -- seems as if I'm getting *Too much* coherence. Of course it could be the settings. Could be " noise " , too (interference?) and not really measuring coherence at all.

Pete,I have been told by several people not to push too hard with alpha-synchrony forward of the central strip.  The logic was that " the front of our brain should be operating at faster frequencies " which is generally true from what I understand.  This also made me wonder if training alpha-synch at C3/C4 was a good idea too.  Shouldn't we be catching and rewarding sudden increases of SMR in the central strip not synchronous alpha?

I don't think a little bit of alpha-synch rewarding will hurt frontal or central brain activity but as a weekly training regime it does seem illogical.  It also really makes me wonder more about the work of Jim Hardt and Les Fehmi.  What are the long term consequences of encouraging alpha activity across the entire brain?

,I don't train synchrony in the front (except training down high fastwave coherence), though Les Fehmi includes these sites.the key is to understand that alpha shouldn't be dominant in front, but that doesn't mean that the alpha that exists there shouldn't be synchronous.  

Still, in most cases, training it should be done in the parietals/occipitals.  You can train in the central strip as well.Alpha synchrony relates to the brain's ability to keep the channels clear and open when the neurons are not active.  It's not just about raising alpha amplitude.

I use P3P4 and put a ground at like Cz

You could also go as far as T5 and T6 as well

Pete, does protocol mean design? if so, I've attached the design I'm using. thanks.On Tue, Jun 26, 2012 at 8:37 AM, pvdtlc <pvdtlc@...> wrote:
