Dear NI experts,
I am a researcher who records EEGs in response to acoustic sounds. Here is the setup in my lab:
Recently, I want to build a similar system but on wheels, so that I can move the system around and record EEGs elsewhere. Here are the devices that I already have and plan to use on this mobile system.
However, I do not know what devices should be used on the mobile system, to replace the functionalities of devices #4, #5, and #6 listed above.
Any comments and suggestions will be greatly appreciated!!!
Solved! Go to Solution.
A better option to generate acoustic signals would be the Sound & Vibration series AO cards, this will produce a clean sinewave and you can skip #4, based on your selection of this AO card, you can even skip#5.
If the EEG signals are a mix of sines, you can get Sound & Vibration series AI cards, they have better dynamic range and retain frequency components well.
Talking about the portable unit, these instruments can fit in a cDAQ chassis and connect to a laptop or a computer.
