Channel electrodes positions


Hey there,
I am relatively new to Muse and I have a simple questions: On the Muse Developer Site, under “Research Tools --> Available Data”, it says that the electrode positions are [TP9, Fp1, Fp2, TP10]. In the PDF on the site “Hardware & Firmware --> Hardware Specifications”, it is though stated that the positions are [TP9, AF7, AF8, TP10].

Can someone please confirm which one is correct ?


The front two electrodes are a fixed distance apart, so whether they are FP1/FP2, or AF7/AF8 depends on the head size of the wearer.

Originally all documentation stated FP1/FP2, but newer documentation states AF7/AF8; most likely as this would be more correct with the average head size.
