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.

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…

2013-11-05 – 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.

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.

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.

I woke up at 0841 right out of a dream.

2013-05-24 – 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.

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.

2012-10-05 – Filtered Out

REM Sleep Graph
The respiratory artifact filter has been ignoring too many events that could have had potential, so I have some more tweaking to do. In the minute above there are over two dozen movements that failed to trigger the audio track.
