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

Previous message: [Neuro] Neuro Digest, Vol 31, Issue 3
Messages sorted by: [ date ] [ thread ] [ subject ] [ author ]

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.

=Pulse Choker Hack Notes July 29th, 2009=

==Pulse Circuit==

Using the [http://www.google.com/url?sa=t&ct=res&cd=6&url=http%3A%2F%2Felectronicdesign.com%2FGlobals%2FPlanetEE%2FContent%2F887.pdf&ei=YjlmSsO-GIGsswO_-PXdDg&rct=j&q=optical+heart+beat+circuit&usg=AFQjCNH9Z1TNjAXLQgcEffPhpZKDL2vTUA circuit] that I found, I wired up a heart beat sensor. It WORKS! But, like the watch, it's difficult to get the optical sensor and your finger "aligned" correctly, so it often doesn't give a signal. I had the best luck when I pressed my thumb into the sensor, with my index finger holding the other side of the sensor with low to moderate pressure. When it does give a signal, the LED seems to blink at *half* the speed of your heart, i.e. each beat causes a state change (from on to off or off to on). This is really puzzling, since it should blink at the same speed. It also seems to miss a fair number of beats. Is it really working? Picture:

[[Image:OpticalHeartBeatCircuit.jpg]]

You can see the sensor, it's the little black box on the left of the group of three. The IC is a dual op-amp, the other black boxes are the transistors. The RBBB arduino clone is being used only for the 5V regulator.

Given this experience, and having had the same experience with the pulse watch, I think that the idea of just pressing the sensor into our necks and hoping it's going to work is totally out. However, it's still possible that a solution involving clipping the sensor to your ear-lobe might work, since that can (hopefully?) be made secure and non-variable. We need to experiment with this.

Anything you clip to your ear-lobe with some amount of pressure, begins to cause pain after a few minutes. (tried it with EEG-reference electrodes) --[[User:Rain|Rain]] 13:23, 30 July 2009 (PDT)

==ECG Idea==

At the same time, I think we should move forward with a different mechanism for sensing heartbeat, such as the industry standard electrocardiogram units. The downside here is that we will probably have to have some kind of chest band or similar. I found the [http://www.open-ecg-project.org/tiki-index.php?page=Small+2-Lead+ECG Open ECG Project's "Small 2-lead ECG], which actually has complete schematics and BOM, along with nice graphs showing how great the heartbeat signal is.

The problem with ECG from our perspective is that it requires electrodes on your body, and that's not cool. The Open ECG project has a page on [http://www.open-ecg-project.org/tiki-index.php?page=Reusable+electrode+development reusable electrode development] which actually links to [http://www.textronicsinc.com/ Textronics], a company that is developing a *fabric electrode* (awesome! - they are doing great work!). They sell a dev kit for $100. Before we purchase that though we should prototype an ECG circuit and use the Red Dot electrodes, to prove that this stuff works for us. Also, I think we could build our own fabric electrodes once we've seen theirs - I mean, some conductive fabric and a strap of some sort to hold it against your skin, right?

==Plans==

I will protect the heart-beat sensor circuit breadboard and we can continue to play with it over the coming weeks. For instance, we have many more sensor heads, maybe some of them will be more forgiving than the Honeywell HLC1395 that the circuit calls for? We also need to feed the signal into the Arduino and see if we can output heart rate info, plus control any display we eventually build. Lots of good stuff to look forward to!

=What is EEG?=
[http://en.wikipedia.org/wiki/Eeg EEG] is a method of reading brain activity using electrodes on the scalp. We're currently trying to get a working setup that will enable us to measure [http://en.wikipedia.org/wiki/Alpha_wave alpha]and [http://en.wikipedia.org/wiki/Beta_wave beta waves], as well as providing a good enough resolution to collect some [http://en.wikipedia.org/wiki/Event-related_potential ERP] data.

*[http://www.youtube.com/watch?v=suKTlrzaU9g Playing pong using EEG]. (''need to research whether this uses ERP or what cause it's cool...'')

=What is OpenEEG?=
OpenEEG is an open-source EEG hardware design. [http://openeeg.sourceforge.net/doc/ The OpenEEG homepage] has more information.
[http://www.olimex.com/gadgets/openeeg.html Olimex has the boards available for purchase]; it seems like a good reference design to use.

*mental multi-player games: train relaxation, concentration, ability to shift mind-state consciously

There will be more documentation coming, and it would be fun to work on it together, create more working neuroheadset setups, and play multiplayer-mindcontrol-games at a workshop at Noisebridge later this year. --[[User:Rain|Rain]] 15:45, 28 July 2009 (PDT)

=Meetup Notes=

==Meetings 4/16 & 4/19==
*On Thursday we had a brief, disorganized meeting that mostly consisted of being really excited about our new cap! It came this week.
*Also, had a new member on Thursday who's interested in using EEG for sleep study. This would be a useful direction to pursue, because it requires minimal, tough hardware, and data analysis wouldn't be too complex.
*On Sunday, almost no one showed up--we assume people will be vocal about it if Sunday meetups don't work for them? But we did talk about another new project that sounds fun: ambient acoustical biofeedback for meditation.
*A couple of our members have actually played with data at this point (see list archives, wherever those are--link anyone?) so that's progress!

==Meetup the Second==

*'''Boards''' - We talked about boards and amplifiers.
**The OpenEEG system has one processor board and can support up to three amplifier boards (we have one now). Each amplifier board supports two differential input channels. Jonathan doesn't think this is the critical path yet, but it might be later.
**Apparently Mitch also has a set of boards (Tracy will check?), and Jonathan may have a lead on another (pun sadly intentional).
** Jonathan volunteered to look at the serial interface from the OpenEEG processor board.
*'''The Cap''' - Rachel is going to buy the [http://www.electrodesales.com/cap100c.html CAP100C EEG Cap Kit]. Please give her your money. (Rachel, will you accept PayPal?)
**What connectors does this have?
*'''Facial & reference electrodes''' - We need to figure out how reference electrodes work with the headset.
**Our amp boards have differential input channels. We need to understand how these connect to single-ended and reference electrodes.
**Discussed facial data in [http://www.youtube.com/watch?v=7utG3NqhBoU Emotiv headset] and adding some facial & reference electrodes to the our headset setup.
**''Research implementations of the cap'' & sort out amplification and reference electrode setup.
**Kelly vaguely remembers something about localization using dipoles and wonders if this would be useful. Needs research.
*'''Enclosure''' - We need to set up a case of some sort and mount the boards in it with connectors. ''Tracy will take a lead on this.'' Jonathan will advise: very straightforward, just drill a few holes & solder a few leads once connectors are specified.
** We need a design decision on connectors. One-channel BNC or differential-channel mini-XLRs?
**Tracy brought a very pretty metal box. In Jonathan's opinion it's a little tight for several boards plus panel-mount connectors. Jonathan suggests a 1-U rack mount enclosed chassis if we can find an affordable one.
**Sanity check our grounding and filtering setup with EKG data since we don't have a clean electrode setup for EEG yet. Will be first step with enclosure.

==First meetup: 2009-03-26 20h00 at 83c==

Agenda:
* Who's here, and what are they interested in?
* What do we have available, and what do we need?
* How do we get what we need?
* Who's going to make that happen for the next meeting?

===First steps===

It sounds like our steps are the following:

* Assemble a set of OpenEEG boards
* Get together a set of electrodes
* Get the data into a computer

Once we've done that, let's look at heartbeats. They're big and easy to see. This is also a good first step towards bootstrapping the data analysis part.

After we've gotten good signal, we can move on to strapping the thing to people's heads and looking for brainwaves. This is where things get interesting. We can export the data and throw it over to the wacky [[Machine Learning]] meetup, we can tie it into crazy [[Sensebridge|Cyborg]] group stuff, make, and we can use it as an input to other systems (be they security, music, or teledildonics).

Here's Jonathan's sketch of a plan, which sounds reasonable to me:

# Get a pool of OpenEEG cards. I would suggest starting with 8. Maybe several people want to "adopt" one by buying a kit and we can have a solder party. I will adopt one myself.
# Put them all in a metal box with a solid ground.
# Find someone with a 8-channel USB-audio interface for signal acquisition. These are pretty common with the musician crowd. (Sample rate is overkill, but that's OK). Anybody have one we could borrow? (Update: These may not have sufficient low-frequency response so may start with OpenEEG ADC).
# Find some good electrodes. Sanity check each channel by detecting heartbeats. (If we can't get those loud and clear, no point looking at the brain's much weaker signals.)
# Now are we ready to do EEGs. I would suggest -- nay, insist -- on a double-blind protocol, otherwise we will see results that aren't there. It's simply human nature. So get subject(s), over several trials, to say, attempt achieving an alpha state, and for a control, I don't know, read BoingBoing or something. Get a third party to randomize the order and keep track of data labels. (Might experiment with event response potentials too as long as we're all set up.)
# When you have some data, call in the geeks. I am personally expert at Fourier analysis, and have some experience with LDA (linear discriminant analysis) using SVD (singular value decomposition). I'd be happy to share what I know (including open-source tools like Octave and SciPy) and chew on the data for an evening.
# Bootstrap from there, as this may not work at all.

*On Thursday we had a brief, disorganized meeting that mostly consisted of being really excited about our new cap! It came this week.
*Also, had a new member on Thursday who's interested in using EEG for sleep study. This would be a useful direction to pursue, because it requires minimal, tough hardware, and data analysis wouldn't be too complex.
*On Sunday, almost no one showed up--we assume people will be vocal about it if Sunday meetups don't work for them? But we did talk about another new project that sounds fun: ambient acoustical biofeedback for meditation.
*A couple of our members have actually played with data at this point (see list archives, wherever those are--link anyone?) so that's progress!

==Meetup the Second==

*'''Boards''' - We talked about boards and amplifiers.
**The OpenEEG system has one processor board and can support up to three amplifier boards (we have one now). Each amplifier board supports two differential input channels. Jonathan doesn't think this is the critical path yet, but it might be later.
**Apparently Mitch also has a set of boards (Tracy will check?), and Jonathan may have a lead on another (pun sadly intentional).
** Jonathan volunteered to look at the serial interface from the OpenEEG processor board.
*'''The Cap''' - Rachel is going to buy the [http://www.electrodesales.com/cap100c.html CAP100C EEG Cap Kit]. Please give her your money. (Rachel, will you accept PayPal?)
**What connectors does this have?
*'''Facial & reference electrodes''' - We need to figure out how reference electrodes work with the headset.
**Our amp boards have differential input channels. We need to understand how these connect to single-ended and reference electrodes.
**Discussed facial data in [http://www.youtube.com/watch?v=7utG3NqhBoU Emotiv headset] and adding some facial & reference electrodes to the our headset setup.
**''Research implementations of the cap'' & sort out amplification and reference electrode setup.
**Kelly vaguely remembers something about localization using dipoles and wonders if this would be useful. Needs research.
*'''Enclosure''' - We need to set up a case of some sort and mount the boards in it with connectors. ''Tracy will take a lead on this.'' Jonathan will advise: very straightforward, just drill a few holes & solder a few leads once connectors are specified.
** We need a design decision on connectors. One-channel BNC or differential-channel mini-XLRs?
**Tracy brought a very pretty metal box. In Jonathan's opinion it's a little tight for several boards plus panel-mount connectors. Jonathan suggests a 1-U rack mount enclosed chassis if we can find an affordable one.
**Sanity check our grounding and filtering setup with EKG data since we don't have a clean electrode setup for EEG yet. Will be first step with enclosure.

==First meetup: 2009-03-26 20h00 at 83c==

Agenda:
* Who's here, and what are they interested in?
* What do we have available, and what do we need?
* How do we get what we need?
* Who's going to make that happen for the next meeting?

===First steps===

It sounds like our steps are the following:

* Assemble a set of OpenEEG boards
* Get together a set of electrodes
* Get the data into a computer

Once we've done that, let's look at heartbeats. They're big and easy to see. This is also a good first step towards bootstrapping the data analysis part.

After we've gotten good signal, we can move on to strapping the thing to people's heads and looking for brainwaves. This is where things get interesting. We can export the data and throw it over to the wacky [[Machine Learning]] meetup, we can tie it into crazy [[Sensebridge|Cyborg]] group stuff, make, and we can use it as an input to other systems (be they security, music, or teledildonics).

Here's Jonathan's sketch of a plan, which sounds reasonable to me:

# Get a pool of OpenEEG cards. I would suggest starting with 8. Maybe several people want to "adopt" one by buying a kit and we can have a solder party. I will adopt one myself.
# Put them all in a metal box with a solid ground.
# Find someone with a 8-channel USB-audio interface for signal acquisition. These are pretty common with the musician crowd. (Sample rate is overkill, but that's OK). Anybody have one we could borrow? (Update: These may not have sufficient low-frequency response so may start with OpenEEG ADC).
# Find some good electrodes. Sanity check each channel by detecting heartbeats. (If we can't get those loud and clear, no point looking at the brain's much weaker signals.)
# Now are we ready to do EEGs. I would suggest -- nay, insist -- on a double-blind protocol, otherwise we will see results that aren't there. It's simply human nature. So get subject(s), over several trials, to say, attempt achieving an alpha state, and for a control, I don't know, read BoingBoing or something. Get a third party to randomize the order and keep track of data labels. (Might experiment with event response potentials too as long as we're all set up.)
# When you have some data, call in the geeks. I am personally expert at Fourier analysis, and have some experience with LDA (linear discriminant analysis) using SVD (singular value decomposition). I'd be happy to share what I know (including open-source tools like Octave and SciPy) and chew on the data for an evening.
# Bootstrap from there, as this may not work at all.
