And then from the halograph FM channel at 0333:
Lost signal with a false positive at 0411:
That should be enough for me to add a signal quality channel and avoid false positives.
Caught a nice flight of stairs from the OpenEEG channel in the minute below.
The signal quality tapered off here and there after that, which can only be seen in the raw EEG data… will add a signal quality channel to keep track of it.

An interesting change in the heart rate variance in the top-right corner that might be indicative of REM sleep:

An exercise I picked up while practicing Bujinkan. The first printout shows four deep breaths a minute:
The second printout shows the rapid “shining” breaths, 60 active exhalations and passive inhalations in one minute:
Notice the effect on the EEG channel. It feels exactly as pictured above. Although I have suspicion that a change in skin conductance (GSR) might be causing some artifacts. Perform Kapalabhati thusly:
Sit in the Lotus posture if possible and hold the head erect. Begin with an exhalation brought about by a rapid inward stroke of the abdomen. Inhalation follows immediately by relaxation of the abdominal muscles. Thus, inhalation is passive and automatic. Repeat this exercise at the rate of one exhalation per second. Look up at the end of the exercise, exposing the throat and hold the breath with the diaphragm.
Previously it was specified that the Lotus posture of yoga be employed for this exercise. The reason will now become apparent. When the breathing exercise described herein is properly performed over a long period, certain vibrations begin within the body. The vibrations, coupled with a feeling of exhilaration, lessen motor control of the limbs. In the Lotus, the legs are in a position impossible to undo without the aid of the hands.
This exercise is used to develop concentration.
Do not attempt while driving or operating machinery!

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:

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…

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.
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.
And peaked with eye movements like this 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.

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.

Encouraged by the findings of Masao Yaso, Atsuo Nuruki, Sei-ichi Tsujimura and Kazutomo Yunokuchi, I have started working on an algorithm to detect REM sleep from the pulse…
