Ganglion: Detecting other brainwaves other than alpha

koroniko

Greetings!

Is it possible to detect ERP's or Mu Rhythms reliably with a Ganglion?

Thank you in advance!

@wjcroft Thank you for your reply!

I would also like to ask something else.

The article mentions that there is a design flaw in the board and ERP measurement will be problematic. Would I have to replace the capacitors 

to be able to detect ERP's or can I get away with the default capacitors?

Also, would others EEG bands be affected if I changed the capacitors?

Thanks again!

Nick, hi.

Alex's tests were made with the original capacitors.

See this thread, all Ganglion boards now shipping have the new capacitors,

Hello William! 

Since I bought the board a while ago I guess I'll have to make the modifications.

Thank you very much for your help!

Measure the capcitance of your capictors to verify you don't already have the right values!
