Measuring EEG signals in real-world environments is tough. Unlike a
controlled laboratory environment, electrical noise from power lines,
computers and other devices easily overwhelms a conventional,
unshielded EEG system. Subject movements can induce large amplitude
electrical and physical noise overwhelming the tiny EEG signal.
To make real-world EEG acquisition possible, the Freedom 10R uses a
highly optimized combination of sensors, mechanics, and electronics
to eliminate unwanted artifacts.
10 sensors positioned at choice of F3, F4, C3, C4, Cz, T3, T4, Pz, P3, P4 locations
of the 10-20 international System.
