Category: REM Sleep
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.
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.
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.
Thought I’d do the process in bullet form. To be used in conjunction with the attached pics. Unfortunately I didn’t take step by step pics but it is really pretty simple. If I forgot anything feel free to ask.
- Remove all the stickers from the mind wave including the large circular one that says NeuroSky MindWave. They just peel off.
- Unscrew everything
- The blue wires Going to the forehead sensor can be carefully pried out of the sides.
- Gently remove the boards and refer to pics for wiring scheme. These wires/connections are fragile!
- Buy a battery holder or cut away the original one and add wires to be able to mount it in a more comfortable position.
- Adapt or replace the forehead sensor
- Mount into headband as suits your needs.
- Sleep, Dream, Be Amazed
According to a team of neuroscientists at UW there are:
Neurons in the mammalian brainstem that focus exclusively on new, novel sounds, helping humans ignore ongoing, predictable sounds. The neurons are located under the cortex in a part of the brain called the inferior colliculus. These neurons provide a unique model that can be used in the future to explore some of the neural mechanisms underlying memory, prediction and selective attention.
So instead of just introducing new signals to attain lucidity, it may be worth further investigation to trigger lucidity by removing persistent signals…
