Re: [AUDITORY] Efficient Brain Recording - Audio to EEG

[Jonathan Z Simon <jzsimon@xxxxxxx>]

Hi Malcolm,

My guess is that it would be a 40 Hz click train presented at a high amplitude (e.g., comfortably loud). You should be able to see a 40 Hz peak in the response DFT pretty quickly, maybe 10 seconds in, on Cz.

Is there a consensus about what is the most *efficient* way to establish that there is an audio-brain-recording connection?  By efficient I mean in terms of the least amount of subject time.

What I want to know is:  how can I mostly quickly establish that we are picking up EEG signals *due* to an audio signal?

I suspect ABRs, since they are used in infant screening.  FFRs seem interesting because they are continuous.  ERPs seem more problematic since they often have a low repetition rate.  (Acknowledging that strictly speaking the ABR is a form of ERP.)

Is there a written comparison?

Thanks.
