<pre>
We use nonlinear mapping and multidimensional scaling into 2-space to identify itinerant chaotic trajectories
through sequences of nonconvergent attractor ruins in the attractor landscapes of brain state space.
The attractors are created and modified by reinforcement learning based on classical and operant conditioning.
Neural modeling includes demonstrations of the neural mechanisms that ensure in all cortices the stability of
neural populations that supports rapid and widespread state transitions by virtue of small-world and scale-free
network architecture. Neocortex is unique among cortices in maintaining global self-organized criticality,
in which the critical order parameter is the global level of neural synaptic interaction that everywhere locally
is homeostatically regulated by neural thresholds and refractory periods.

Classify audio waves via brain monitoring

Thermal infrared camera to monitor blood-flow in the brain

IR cameras to measure full specture, rather than stricly amplitude
Could construct a small array of infrared sensors -- more economic

[Neuro] Coming soon to Noisebridge - The Dream Team
bfb at riseup.net
Wed Apr 24 18:00:00 UTC 2013

Hello Noisebridge!

We shall meet on Wednesday, May 1, at 6:30, because we're all stars!
Python class is over, now let's put that good know-how to work on some
maths and science stuffs. There may also be comestibles, just this once.

Come down to the 6:30 share-a-thon. Discuss your dreams and other
applications of neuron-monitoring devices. I want to investigate lexical
dream content and brainwaves of people all over the planet, starting
with Noisebridge. Thus far, I have an EEG device and a semi-incomplete
research facility (HSNPs).

To get up to speed with what I've been looking into read on. And all you
varied neuro-hackers out there please do go to the brainliner.jp site,
it's amazing.

I've attached a copy of a sample data set taken while writing this
message. Also attached is a screen shot of the GUI that the python
scripts create. The scripts run great on Debian. The dongle that comes
with the device has an antenna to pick-up the WiFi transmissions from
the device. It opens the right sockets, makes a few hand shakes, and
promptly peaces out. Neurosky purports the device will give a good
signal up to 10m. It spews ~500 measures per second.

https://github.com/akloster/python-mindwave

This is the EEG device. Specs included.

http://store.neurosky.com/products/mindwave-1

And here's a link to Yukiyasu Kamitani's landing page with ATR, Advanced
Telecommunications Research Institute International. He's head of the
Department of Neuroinfomatics, and lead reacher on the publication
below. They are working on predicting dream sequences from EEG and MRI
data taken while asleep.

http://www.cns.atr.jp/dni/en/members/kamitani_e/
http://www.cns.atr.jp/dni/en/publications/

Kanitani and others are open-sourcing a good bit of their work. See git
hub repository and standardized repository for sharing neuro-data below.
They're set-up to run in Mat Lab, but w/e.

Really, go to brainliner and then giggle crescendoing into mad-scientist
roar.

http://brainliner.jp/
https://github.com/ATR-DNI/VBCCA

And finally, to pass on a message from a friend, because it's open in my
browser and seems appropriate.
https://raw.github.com/videlalvaro/gifsockets/master/doc/mybrain.gif

See you Wednesday.

-Kevin
