Hey your high dudeness. –
Friendster has turned out to be an interesting social anthropology
experiment. I have 51 first degree
friends in this network, 3239 second degree friends and 197,948 third degree
friends. So as you can see, the reach is exponential. The
reality is that I talk with three people regularly. An
artist in San Fran, a publicist in
Check out these two ideas. I had my weekly migraine last night, after I woke up I was
thinking of this:
1) The glowing blob. You know traditional 16 or 63 lead EEG's? Of course you do.. Anyway,
there are huge vaults containing hundreds of thousands of EEG tapes. Whatever.
The idea is this:. How about
visualizing the data against a model of the head rather than endless squiggly
lines showing average evoked potential?
How about a model with a reconstructed virtual source that glows or undulates
corresponding to the averaged probable source voltage density at that lead. It
would be low res compared to fMRI, but still possibly
useful, in cost constrained environments or looking at
the history of a large number of people thinking. Case correlation and all
that.
So
this Jello™ blob represents the brain and the
brightness of the glob at any specific region is the instantaneous solution to
the set of 16 (or whatever) simultaneous equations that would produced that
equivalent waveform as seen at all 16 leads?! I think this blob model would be more intuitive for
assessment, diagnosis and treatment because it would allow a more direct
visualization of the source of the signals. So that is idea #!.
Footnote.
The eye muscles are notorious for creating signals that swamp weaker signals
being sensed. But in this case the eye signals could
be used to calibrate both location and intensity of a known source and thus
serve as a standard reference for distribution of voltages in the head. Blah blah blah
2) Sometimes I wear my red and blue 3D glasses to protect my
eyes in bright sunlight because I am a starving film producer and cannot afford
new sunglasses. I wear them around town, producing stares, questions, and fall
colors in interesting z axis offsets. (I must remember
that the stop light is on TOP of the pole!!!) The red
lens is over the left eye and the blue lens is over the right eye. Now as you
know, the optic nerve from each eye goes several places. There is a main split
at the optical chiasma, with roughly half of each
nerve, possibly corresponding to blanking the medial nasal hemispheres of
vision. Who wants to see their own nose? There are also smaller splits for
seasonal and time of day sensing. (I could be
hibernating right now!) The idea is this. The red lens causes optical traffic on
the green and blue retinal receptors to quench. So by
having a person look at a colored scene, one could determine a couple of
interesting things.
a) the density of foveal receptors
and their outbound processing pathways.
b)
the degree of optical nerve bifurcation, routing, and function
c) other cool stuff!
Footnote:
One could create, with simple and inexpensive color gels a set of glasses that
were red on the medial (nasal) section and blue on the lateral (outside)
section on each eye. Here is a hacked from my SAG
picture.
Well
that's it. Hope you like it.
Cheers,
