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:

13 Strained Heartbeats at 0005

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:

Triggering lucidity
I finally got my hands on an old Wild Divine LightStone. And finally managed to keep the finger clip on all night after many attempts. I also wore the halograph FM and the heartbeats as measured by the IR sensor from the finger and the accelerometer in the headband line up perfectly. 63 beats can be seen in the minute above.

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…
