Problem with creating an ERP

Hey Muse comunity!

I would like to make a few tests, where i scare someone and want to see this scare in his brainwaves, do you think that a ERP would be the solution to this problem, or does anyone know how i could do this?
If ERP would be the solution, with what programm should i work to get an ERP?

With kind regards,
