- Ensure good skin contact
-- To ensure that skin contact is good, it is important to measure the impedance between the electrodes. - Start by measuring the impedance between your active electrode and its reference (e.g.: Fpz and Cz). - Also, check the impedance between the reference electrodes of each channel (Cz and Oz) and the ground - electrode (A2). As a rule of thumb, low impedance (10 KOhms) is good and high ones are bad (let’s say - 150 KOhms). -
-Limit noise
-- Tie the electrodes together with a hair tie, and if you have long hair, tie them all together in order - to avoid static during the night. To limit electromagnetic interferences you may want to place your - board in some sort of Faraday cage, for example, a plastic container wrapped up in aluminium foil. -
-How to use OpenBCI GUI
-- First thing you need is the OpenBCI GUI in order to use the hardware. Therefrom, select{' '} - Live (from <boardname>) as your source. If you’re using a Cyton board we suggest you use a - microSD card using FAT32 format. If you do so, do not forget to select at least 12 hour maximum for - the write to SD card parameter. Otherwise, you must keep your computer near and open for the whole night and - log the data to a session file. If you do it this way, do not forget to select the OpenBCI file output and - to select No Limit as your max file duration. When everything is configured properly, you can press{' '} - Start Session. Before pressing Start Stream, press Hardware Settings and configure - everything as follow: -
- -Cyton
-Ganglion
-- Do not forget to deactivate all unused channels by greying out the numbered colored pill on the left of the - signal in the GUI. You can now press Start data stream. If you are using a microSD card and a Cyton - board, you may want to pull off the dongle from its usb port. Data will be written to the SD card for the - configured amount of time. -
-Write a journal
-- You must keep a journal (accurate to the minute) and write down a few information to help us track and - analyze your sleep: -
-
-
-
-
You will need to provide this information in order to score your EEG recording.
-Wake up!
-Remove your electrodes
-- In order to take the electrodes off your scalp, you can use warm water for the EC2 to come off easily. The - Hypafix, used for electrodes over the skin, should be taken off with warm water and/or rubbing alcohol. - Prefer taking them off slowly, since they can hurt sensible skin if removed too quickly. Don’t forget to - clean your electrodes using warm water and soap. -
-If you used an microSD card:
-- Remove the microSD card from the board and insert it in your computer. Then, open OpenBCI GUI and select{' '} - PLAYBACK (from file) as your data source. Use the Convert SD for playback option and select - your sd file. Wait a little bit and you will get the converted csv file. Upload this one to this website - in order to score your sleep -
-If you used session file:
-- After stopping the stream, go to the Recordings directory where your session file. Just upload this file - in order to score your sleep and analyze your data. -

- - -Analyze my sleep
++ Now that you have your recorded sleep data file, you will need to install and run the sleep analysis server. + Then, you will be able to submit your recorded data to the Polydodo sleep analysis algorithm. When you are ready + to proceed, perhaps after a sip of coffee, it's right there: +
+ +Connect the electrodes
+Here is how you need to connect your electrodes to the OpenBCI board you are using:
+
+
+ 
+
+ Connections table for each electrode
++ The headers pins of the electrodes can be disconnected rather easily. Make sure that no pressure is exerted on + the wire at any time. On our side, we decided to tap the wire on its container, in order to avoid such a + scenario. It is now time to power your OpenBCI device. We suggest full charged batteries, since the device + will be powered on for several hours. +
++ {titlePrefix} + {title} +
+How to place the electrodes
+ +Apply skin preparation gel
++ Pour a small amount of abrasive paste where your Fpz mark is and exfoliate the skin with a cotton swab until + it begins to turn pink. Using rubbing alcohol and a cotton swab, wipe away the skin several times in order to + remove dead skin. Repeat this for all marked locations. +
+Place the scalp electrodes (Cz, Pz and Oz)
++ First, make sure your electrodes are clean. For more info on how to wash them, see the Wake Up section below. + Then, follow these three steps: +
++ Finally, take the gauze pad with the electrode and the EC2 and place it on the marked area. Exerce a small + pressure on the gauze square with your palm. The electrode should stay in place. The EC2 conductive paste + should take a couple minutes to dry (try to avoid sudden movements). Repeat these steps for the two others + scalp electrodes. +
+Place the skin electrodes (Fpz and A2)
++ As with the scalp electrodes' first step, fill the electrode cup with a good amount of Ten20. Afterwards, + cutoff a small piece of Hypafix. Place the electrode over the mark and apply the Hypafix medical tape tightly. + The electrode should be secured under the tape. +

+ Where to place the electrodes
++ First, you need to know where to place the electrodes. You will need the soft tape measure to measure the head + according to the 10-20 placement system and then you will mark as precisely as possible each electrode's + location using a marker. The montage is composed of the Fpz-Cz and Pz-Oz channels to which we add a driven + ground electrode placed at A2. This montage is based on an alternative electrode placement for sleep analysis + [Sweden, Kemp, Kamphuisen and Velde, 1990]. +

+How we did it
+ ++ On these photos, we can clearly see the application of the electrodes. Please ignore the electrodes placed + at chin and eye level (they were used for manual data scoring purposes). For this recording, we used the + Cyton board and a microSD card. We put the board in a disposable plastic container that we covered with + aluminum foil, to limit EMIs. Then, we put the container in a camera bag worn with a shoulder strap to be + able to carry the board on us. +
+ ++ Here is a comprehensive guide that explains how to record your own EEG data with an OpenBCI board. The proposed + method ensures that the recorded data will be compatible with Polydodo. This guide presents the list of needed + materials, the positioning of the electrodes, their placement, as well as their connection. After, it will focus + on configuring the OpenBCI boards and on what to do overnight. Be sure to follow our tips and tricks on how to + maintain a good signal to noise ratio. Note that the supplies and the application methods are meant to follow + best practices and to provide good quality data. +

+What you will need
++ If you already own an OpenBCI board and some basic EEG equipment, you could have very little to buy except a few + things from the drugstore. Some of the brands that we mention have their equivalent and can be replaced. We do + not advertise the mentionned products, but we have used them and found them useful and of good quality. +

+Retrieve your recording
++ If you used a microSD card, remove it from the board and insert it in your computer. If you used the session + file way, after stopping the stream, go to the Recordings directory where should be stored your session file. +
