Removing electrodes from pinset

[drmrfzl]

Hello -

I work in a lab that does polysomnography, currently using a 32-pin active electrode set. However, a point of contention for me and some in our lab is that 32 electrodes are not required for the data we are collecting - only 6 are.

This may be a crazy question, but is there a safe way to remove electrodes from a pin set? Ideally, we would not have to purchase a whole new pin set (and as far as I am aware, BioSemi only goes down to 16 pins - not including the 8-pin EX1-EX8 set - which is an improvement but still more than we need), but I realize that may be the best option.

I apologize if this has been discussed before on the forum, I did a search and did not find anything. I appreciate any advice anyone has to offer!

Use 6 so called TP-pin electrodes connected to the EX inputs.

Thanks for the reply! However, we use the EX inputs for face electrodes. Is there any way to increase the number of EX inputs (i.e., signal splitter)?
