The types of sensors which receiving Brain SignalsH

[BMEinstein]

Hi :)
I'm designing a research and need you guys's help :)
It's an experiment to finding out what happens in our brain when we are stimulated by electricity.

I have to collect the signals from brain, but not using EEG.
(I already failed once...:'( )
I've been thinking about MEG, but it doesn't seems bringing good result 'cause you know, electric/magnetic fields are so mutual..

So could you notice us if there are any other sensors which can collect brain signal??
(It's small experiment so enormous equipment like (f)MRI couldn't be used..)

Thank you a lot. :D Have a nice day :D
