i must Apologize to you, if, in prior posts, i 'steered' you 'wrong'.

the main thing that i was referring to, when i discussed "EEG-type" studies
was the need to acquire rigorously-arrayed data, and to cross-correlate it
with everything else with respect to which it can be cross-correlated,
including via the topological 'twists' and 'turns' of the neural topology.

maintaining the spatial geometrical] rigor is the most-important thing.

EEG is rather imprecise in this regard, so it's better to record the
analogous data via arrays of electrodes.

i've no lab, so i can't help with specific technique. i developed this view
while studying the literature with respect to single-unit recording, piecing
together a version of the 'array' data, over 'time'.

it wasn't long before i began 'wondering' why no one was [back then; 1970s]
using arrays of recording electrodes.

such arrays came into use during the 1980s.

the main difficulty with them is that the denser the recording array, the
more it's placement tends to destroy the natural Geometry [neural topology],
so it can confound itself. there's always some of this, even with single

perhaps some of this can be controlled for via electrode, and non-electrode,
EEG, but this, too, will be confounded when the electrodes are in-place.

i wanted to give you this info, and to Apologize to you for not just saying
"spatial-array-data" in my prior posts, because the 'dream' inherent in your
overall approach is Splendid, as is your professed dedication to its

i Engourage you, from my 'Heart'.

know that the course you've chosen is 'Difficult', demanding, and requires
pains-taking deta-base construction with respect to the 3-D neural Topology.

but, if you only stick with it, and if you work with sustained rigor, your
success is guaranteed.

go for it.
