BP-REM

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

Kapalabhati

An exercise I picked up while practicing Bujinkan. The first printout shows four deep breaths a minute:

4 normal breaths

The second printout shows the rapid “shining” breaths, 60 active exhalations and passive inhalations in one minute:

Effect of Kapalabhati on EEG

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!

Controlled Doses

I now have the current-stimulation delivery system smoothed out to where it only zaps for one minute and waits at least ten minutes between doses, and finally managed to sleep through without interruption. Still no lucidity, but I had exceptionally vivid and long dreams again.

tACS at: 0214, 0224, 0339, 0349, 0400, 0412, 0516, 0528, 0538, 0549, 0601, 0611, 0705 and 0716.

Perpetual Dose

I lowered the dose to 1mA or just under and the effect is still noticeable as the EEG picks up the extra current, but much more subtle than before:

It first triggered at 0220 (pictured above), and even though I had updated the USB relay plug-out for the tACS to turn off after 1 minute and rigorously tested it while awake, the Zeo plugin kept re-triggering it after a minute, keeping it on perpetually. After 8 minutes, it must have tried to re-trigger just before the minute was up and gave me a break for a minute. Then it administered another 8-minute-long dose and during the break at 0238, the signature of a lucid dream appeared – going from REM to awake and back to REM, although I have no memory of it:

After that, the USB relay was stuck in the on state for 15 minutes until the EV-806A beeped and I woke up at around 0257 with a headache to turn it off manually. I then disabled the tACS plug-out and went back to sleep without any noteworthy aftereffects.

I also cut the tACS electrodes down to size, as they were taking up too much real-estate on my forehead. The two stick-on electrodes in the corner show the original size. And the electrodes in the halograph show the placement. The middle / ground electrode was positioned in the center of my forehead just below my hairline. The two tACS electrodes slightly lower and to the sides of it. And then the other two EEG electrodes just above my eyebrows:

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…

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: 

13 Strained Heartbeats at 0005

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

Eye Movement Count from EEG at 0017

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.

Supplemental Boost

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.
