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 New York, and an AIDS worker who runs a clinic in Kampala, Uganda.


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.
