Do you really know your neighbourhood?
So, I came across this warning in Fieldtrip toolbox website
The context
- Whenever we use spatially spanning cluster-level statistics, it is very important for the algorithm to know what electrodes are near each other
- Each cap maker has their own way of putting up where electrodes are in space (X, Y, and Z values)
- Somewhere in the study, we choose neighbours for each electrode, either on purpose or by default (mostly by default)
- You may lookup the ftprepareneighbours function to know in depth about common methods (distance, triangulation, template) in this domain
- BY the way, mne uses
Delaunay triangulationfor this and I opened my mouth widely on seeing the warning in mne's documentation page
If you're taken aback by these intricate nuances or wondering what on earth I'm referring to, delving into one of my previous Readme files could provide some clarity
Let's take a step back and examine the issue from its foundation
Take a look at the 64 channel montage from easy cap for actiChamp plus amplifier from brainproducts
- Take
Fzelectrode, who are its neighbours?
- [ ] F1, F2
- [ ] F1, F2, AFz, FCz
[ ] F1, F2, AFz, FCz, AF3, AF4, FC1, FC2
Establishing a neighborhood boundary is tricky (now I know the logic of territory wars). Where does
usend andthembegin if you want to think like Sapolsky. Eh, I've gotten off track. Now, think aboutCz. If you are one of those who thought I was being generous with option C in the previous example, booom!
Hope I have convinced you about Knowing Thy Neighbours. Amen
By the way, you will find a small matlab script which will objectively tell you who are your neighbours based on a simple distance measure calculated from your own cap manufacturer's locations (I mean X, Y, Z locations) in this repo

This code is used for multiple research works where we
define the neighborhood based on the channel location file
provided by the EEG amplifier and cap manufacturers
