Where do you purchase the Styrofoam net to go over the cap as referenced in the Promoting Inclusion in Psychophysiological Research: EEG for Different Hair Types infographic?
Tip from one of the infographic creators, Luke Poole, M.A.: In our lab (PI: Dr. Brandon Alderman, Rutgers-New Brunswick) we use Spandage (MT05 and MT06 sizes in infographic picture) and Surgilast, both available for online purchase via Amazon. We cut 8-10" of netting, fit the mesh from front to back, and then tie off the back with a hair tie or similar fasten. This technique works quite well for our BrainVision system, but as a word of caution, we've heard it can cause tangles and/or minor damage to EGI setups upon removal.
