Tips for EEG recording using Enobio or StarStim devices
Plan well before doing anything
Where do you want to place the electrodes? For how long do you want to record? Do you have a good naming scheme for your EEG files? What data formats do you want to save? Do you need accelerometry data? Do you want a line filter applied to the data (if so 50 or 60 Hz?)?
Do you have an electrode referencing scheme? You should include in your montage a solution for data referencing. Data will be recorded referenced to the device electrical ground (the CMS electrode), but for data analysis you should always reference the data to an electrode or to the electrode average.
Clean up the mastoid area to where you are going to put the DRL/CMS electrodes (using adhesive electrodes)
You can use a paper napkin with some water or alcohol. Removing grease and dry skin will help you get good signal.
Place the DRL/CMS electrodes close to each other, with the DRL on the bottom
These two electrodes should be close to each other but not touch.
Avoid loose wires
Try to have a tidy setup with few loose wires. Loose wires are more prone to creating noise from movement.
