EEG electrode placement for P300.

From Gerwin Schalk, in BCI2000 forum (if 8 channels):
– left:   P3, PO7,
– right:  P4, PO8,
– middle: Fz, Cz, Pz, Oz

Easy Cap, in lab.
– left:   F3, C3, P3, O1, TP9
– right:  F4, C4, P4, O2, TP10
– middle: FPz, AFz, Fz, FCz, Cz, Pz
The configuration of 16 electrodes is from Markus Kroesen’s Bachelor Thesis, 2013, University of Oldenburg
“Vergleich verschiedener EEG-Verstärker zur Steuerung von Brain-Computer Interfaces”
http://www.easycap.de/easycap/e/products/products.htm
note: Markus Kroesen was developing P300 based BCI speller, with EasyMotiv (Easy Cap + modified Emotiv)

From discussion with Mr. A:
– left:   O1
– right:  O2
– middle: Pz

It seems that P3, P4, O1, O2, and Pz are important in P300.
And O1 and O2 can be replaced by Oz.

Easymotiv = Easy Cap and modified Emotiv

Well, it is time consider mBrainTrain, instead of Easymotiv

Ada revisi karena ada tambahan informasi mengenai EEG amplifier yang akan digunakan. Aku berencana menggunakan mBrainTrain, bukan lagi Easymotiv (Easy Cap + modified Emotiv EPOC). Sebetulnya risetku tidak menekankan P300, melainkan motor imagery. Akan tetapi, siapa tahu aku perlu melihat sinyal P300 pada analisis offline pada data eksperimen.
