2014-11-04 – Electrically Vivid

The Zeo triggered 2mA at 40Hz via USB relay half an hour after I went back to bed during WBTB, even though I was still awake. The effect is immediately noticeable as the EEG picks up the extra current:

I had it set low enough so that nothing twitched, but I could feel a pressure which became uncomfortable after a few minutes. It was programmed to run for 15 minutes, which was a little too long. The Zeo recorded the noise for 5 minutes, then went on strike and flat-lined for 10 minutes until the EV-806A beeped and I turned it off manually. The Zeo then recovered and recorded normally again. I will update the USB relay plug-out to turn off after a minute or two for the next run and turn down the amps a few notches.

I unplugged a little while later and went on to have some exceptionally vivid dreams…

2014-10-06 – Climbing BPM

While waiting to get the stage data working on my new Zeo EEG headband, I noticed a few interesting hikes in the BPM right before some electrical activity like in the minute below that could be a starting point for the heartbeat algorithm:

I dusted off my LightStone and set out on a new quest to detect the dream state from the heartbeat. The heart rate variability (HRV) channel sometimes creates castle-like patterns during deep sleep like in the printout below:

This pattern is sometimes interrupted – by movements, bad sensor readings and dreams perchance:

I woke up at 0308 when the electrode gel dried up and triggered a string of false positives from the OpenEEG channel. I stayed up for 30 minutes for some Choline and Galantamine and was plagued by numerous false awakenings over the next 3 hours. I also tried out a EV-806A tENS unit at 40 Hz on Fp1 and Fp2 for a few minutes before sleep.

The BPM channel (grey) sometimes climbs of its own accord – that might be the first place to start looking:

Sleep and Consciousness Research Graph
I started remaining still, then I looked 10 times for each direction(r,l,u,d).
in every change in direction I had a short period of time of stillness.
the axis cannot retrieve the right orientation due to the position of the sensor, which is calibrated for staying in plane on a table. so looking up/down doesn’t mean an Y movement, for example.

Effects of Supplements on Eye Movement at 0135
Thanks to neuralswarm from DreamViews I now have some Choline and Galantamine to test with. I took one of each just before sleep and recorded some nice patterns within the hour during which the audio tracks triggered. The dreams were very technical in nature and I was aware of heightened electrical activity in sections of two-dimensional grids in the frontal lobe.

2014-01-24 – MindWave Keyboard

ET SOS CONSCIOUS
Inspired by Bob’s blink based input device on Hack a Day and Intel’s App Innovation award, I now have the TCMP channel working with the NeuroSky MindWave and other ThinkGear EEG compatible devices. Although the learning curve is much greater, I want to believe that the improved transmission rate and ability to communicate with closed eyes from deeper states might make it worth it for some.

A dot is a gentle blink, so that the NeuroSky EEG channel spikes above 500, but below 900. A dash is more of a frown, or wink or raising of the eyebrows so that the NeuroSky EEG channel spikes above 900. To practice, reference the International Morse Code chart. Start with some E’s (dots) and then a T (dash). Then say SOS and finally CONSCIOUS.

2014-01-08 – Free Fall 2

EEG of Hypnagogic Jerk at 0101

I caught that feeling you get when you are startled awake by an intense falling sensation on file again, this time with EEG. At 0052 I was still awake and making sure the audio tracks were triggering, then at 0101 I twitched awake and checked the time.

The minute above shows the episode – the first spike was the twitch and seems to have flat-lined the channel for a few seconds. The rest of the movements are from me checking the time and settling again.

After explaining the REM-detection algorithm to a friend over the weekend, I was inspired to shed some light on it by plotting each step in the loop on the graph so that it becomes easier to visualize.

The first printout that I recorded last night, 5 minutes past midnight, shows the strained beats picked up by the halograph FM. The fREM channel can be seen counting up each blink or strained beat that peaks over the top line and then triggers the next track in the playlist after the 8th blink.

And the second printout, recorded at 0017, shows the same thing happening with the OpenREM channel from the OpenEEG electrodes.

This will make it a lot easier to perfect the algorithm by highlighting where it was thinking about triggering. The tracks at 0618 made it into the dream and helped me stave off a hoard of zombies, but didn’t trigger lucidity…
