Question 1: Why they are different?
Question 2: Are there different effect in motor imagery using Emotiv system? Do experiment!

Similarity between both caps:

– right: F4, P4, O2

Question 3: Are the references still P3 and P4?

Note:
– AF3, AFz, AF4 are aligned
– F7, F3, Fz, F4, F8 are aligned
– FC5, FC1, FCz, FC2, FC6 are aligned
– T7, Cz, T8 are aligned
– P7, P3, Pz, P4, P8 are aligned
– from previous experience, AFz was ground (GND) and Cz was reference
