Knock, Knock

The four printouts that follow were recorded during the same night with the halograph FM and EEG. 

The first minute, 0143, shows a pattern that I have seen many times: a sequence of heartbeats where every third beat is three times as strong as a normal beat, 12 of which can be seen below. I have begun to suspect that this may be a phenomenon that only occurs in male subjects. Note that the EEG channels flatline.

12 Strained Heartbeats at 0143

Moving on, two and a half hours later at 0408 there are two such beats right before the onset of a marathon REM session that lasted half an hour.

2 Strained Heartbeats at 0408

And peaked with eye movements like this at 0412:

EOG from EEG at 0412

Only to end again with some strained beats at 0450. No idea what to make of that spike on channel 2, it seems to pop up quite regularly.

Measuring the Brainwaves of a Crowd

Brainwaves of a Crowd Waking Up
I happened upon a group of dreamers, 2600 strong, that had fallen for the LUCI KickStarter campaign. A company called GXP Technologies was selling a headband with a sensor that they claimed could detect REM sleep and trigger a recorded message stating: “You are dreaming, take control” to induce lucid dreams 80% of the time. I could tell that it was a scam the first time I looked at it, since it is pretty close to what I have been working on for the last decade… 

As evidenced by the collection of Lucid Scribe plugins that connect to third-party hardware, I would have been among the most excited if it had been a legitimate product. But their EEG didn’t complete a circuit, their induction percentage was unheard of, their amp was orders of magnitude out of the range of brainwaves and – what ultimately exposed it as a scam to the masses: the images of their prototype were created in Photoshop.

I reported it to KickStarter right away, but they didn’t do as much as acknowledge my report. I couldn’t sleep during the last weekend of the campaign as they were about to coin half a million dollars while making a mockery of lucid dreaming research. So as a last resort I backed the campaign in order to post my findings as a comment.

I then witnessed what appeared to be a P300 event-related potential in the attitude of the crowd. On a much slower scale, of course, but similar to what happens in the brain when you recognize something. I have been keeping my eyes out for P300 waves, as I hope to one day find that the onset of lucidity, or the recognition of the dream state, produces such a wave.

Here is some interesting research that was done at the Usenix Security conference:

The researchers designed a program that flashes up pictures of maps, banks, and card PINs, and makes a note every time your brain experiences a P300. Afterwards, it’s easy to pore through the data and work out, with fairly good accuracy – where a person banks, where they live, and so on.

And DARPA used the P300 event to recognize threats. They showed users ten images per second (of desert terrain, for example) and noted which images triggered a P300 – 91% of the time it was because there was a threat in the image that the person might not have consciously recognized.

So I tried my hand at measuring and graphing the “brainwaves” of the crowd. I wrote a script to flip the comments so they appear in order and measured and weighed each comment as either positive (excitatory) or negative (inhibitory). If we pretend that each backer is a brain cell and each comment is a neurotransmitter, then we can plot an electroencephalograph of the crowd.

The printout featured above shows the amount of positive (blue) and negative (red) comments per hour over the last 100 hours of the campaign, with the inhibitory comments peaking at -120. Not as close to what an event-related potential looks like as I expected to find, but interesting nonetheless and entertaining at the least.

The campaign was cancelled after enough people reported it and it was covered on pandodaily, in the Wall Street Journal and in Crowdfund Insider. Shout out to the bodhisattvas Majid, Yeti, Sascha and Mr. Brand for staying behind and waking up the others! And special thanks to Highlander over at the DreamViews forum for sleuthing the name of the amp.

EEG Waves

EEG Graph REM Sleep
I recorded with my halograph FM and EEG in parallel. The electrodes didn’t have the best contact, but they still picked up some interesting readings. I have been embedding the passive electrode in the headband by my temple – a lot more comfortable than the earlobe and it still picks up the eye movements. 

The eight waves in the minute featured above seem to have repeated every hour, around the 50 minute mark, starting at 2 am. The relative quite in the accelerometer channel suggest that the waves aren’t artifacts. I might set an alarm for them one day.

Naturally Lucid

OpenEEG recording of a lucid dream
I had a rare natural lucid dream triggered by events inspired by the main theme of Bob DeNatale’s new film about lucid dreaming, The Art of Dreaming. I maintained lucidity for a good minute of human flight. The minute featured above shows a spike in the data that is otherwise flat, recorded at 0614, when I believe the dream occured. I was asleep from 0015 to 0640. 

The algorithm didn’t trigger an audio track, as it was looking for multiple events like this in a row. I will update it to optionally trigger on only a single event, because of the vividness of the dream. The spike looks similar to when I open my eyes while awake.

Sleep and Consciousness Research Graph
I have make a Remote Viewing Session (german: Fernwahrnehmung) and have recorded my brain with my mindwave headset from neurosky.
The Session is from Stage 1 to 6 , and by the way.. its a Coordinate Remote Viewing Session (CRV).

EEG Baseline

EEG Baseline
The minute above shows the “normal” EEG values when I am still. I can move my head around quite a lot without affecting the values. But as soon as I move or close my eyes, significant peaks can be seen like in the minute below that I recorded during my sleep at 0825.

Open Electroencephalography

OpenEEG Project - REM Sleep
A decade after I was able to afford my first printed circuit board from Olimex and started dabbling in the OpenEEG project, I finally managed to build a device with which I can comfortably record my brainwaves during sleep.It took forever to fall asleep because I was just too excited. I woke up at 0534 from a dream and noted the time. The printout of the minute I selected is from 0515 and shows some very distinct patterns that are similar to when I move my eyes around while conscious. I will use that as a base to write the REM-detection algorithm that will trigger the audio tracks.

I embedded the four active electrodes inside a headband and taped the passive electrode to my earlobe with some duct tape. I still need to meditate on a more convenient way to attach the passive electrode.

It can be worn with the sensors on the forehead by the Frontal Lobe to trigger on the spikes in electrical activity caused by eye movements or at the back to monitor the brainwaves by the Occipital Lobe where visual perception is processed. Check it:

Anyone with a device compatible with the OpenEEG project can now upload to the Lucid Scribe Database project by right-clicking on a log in Lucid Scribe and selecting Export to -> LSDBase. The source code for the OpenEEG plugin is available on GitHub.

First Dream with Modified MindWave
First dream captured with modified NeuroSky MindWave. Anyone familiar with the MindWave knows its design makes sleeping with it on nearly impossible. I took mine apart and remounted the boards, contacts and battery (crudely) in a elastic headband. Now it is possible to sleep with it on.

UPDATE:
Thought I’d do the process in bullet form. To be used in conjunction with the attached pics. Unfortunately I didn’t take step by step pics but it is really pretty simple. If I forgot anything feel free to ask.

  • Remove all the stickers from the mind wave including the large circular one that says NeuroSky MindWave. They just peel off.
  • Unscrew everything
  • The blue wires Going to the forehead sensor can be carefully pried out of the sides.
  • Gently remove the boards and refer to pics for wiring scheme. These wires/connections are fragile!
  • Buy a battery holder or cut away the original one and add wires to be able to mount it in a more comfortable position.
  • Adapt or replace the forehead sensor
  • Mount into headband as suits your needs.
  • Sleep, Dream, Be Amazed

Triggering lucidity
I became aware of the previous song stopping abruptly. Not from the song that started in the minute above. A flurry of eye movements can be seen in the middle of the snapshot with traces of another one of those 30 second waves in the first half. According to a team of neuroscientists at UW there are:

Neurons in the mammalian brainstem that focus exclusively on new, novel sounds, helping humans ignore ongoing, predictable sounds. The neurons are located under the cortex in a part of the brain called the inferior colliculus. These neurons provide a unique model that can be used in the future to explore some of the neural mechanisms underlying memory, prediction and selective attention.

So instead of just introducing new signals to attain lucidity, it may be worth further investigation to trigger lucidity by removing persistent signals…

REM Sleep After Ninety Minutes
The first audio track played exactly 90 minutes into the session and the movements lasted for the duration of the song. I was expecting the vocals to kick and was disappointed when they didn’t. I will have to cut them in as soon as possible. The second audio track played 65 minutes after that; six blinks can be seen in the minute above before it woke me up.Download entry as Lucid Scribe Data (LSD) or Comma Separated Values (CSV).
