similarly I'm trying to figure out where to place my electrodes. My issue is what I'm trying to get from it and which placement would correspond better.
I'm new to this, and in a learning phase, so I'm sorry in advance if anything I ask may seem silly.
According to my readings (and please correct me if I'm wrong), the main points of interests for me would be :
F7 is located near centres for rational activities
Fz near intentional and motivational centres
F8 close to sources of emotional impulses
T3 and T4 emotional processors.
What I'm trying to achieve, is to get users' motivation, excitement, emotional tensions and focus during the usage of a video game type test.
I don't think there's a magical solution and that any one location(as bitalino only has one slot for eeg) can get me all of those, but I'm wondering which one would work best to get closer to my goal considering that I could use in addition sensors for EDA for emotional tensions.
Considering my last statement, I would think an EEG with Fz and the EDA would cover most of what I want. Is that correct?
And in any case, where can I put the reference sensor? and How do I know I'm exactly on the right spot for anything?
Also, is there an issue from choosing T3 over T4 or the opposite? should T3 and T4 always be used together as the function seems symmetrical (but the brain process is most likely not replicated symmetrically)?
Sorry again for the many questions,
