Subject: Re: [AUDITORY] Efficient Brain Recording - Audio to EEG From: "Dr. Efthymios Papatzikis" <efp331@xxxxxxxx> Date: Sat, 29 Jun 2024 08:11:24 +0300Dear Malcom, ABR is a form of measuring audio perception in general at the level of the b= rainstem, so If you are interested to see someone=E2=80=99s ability to hear/= perceive audio in general, yes that=E2=80=99s the case. However, I do not kn= ow of any way measuring different sources of audio vs silence let=E2=80=99s s= ay (for example if someone is able to listen to a specific piece of music at= a certain moment), and then at the same time perform ABR. Technically is no= t possible because ABR is already feeding the auditory system with audio at t= he time of recording. You may be able to perform some monaural/binaural/mask= ing protocols with ABR but I do not think this is what you are looking for, c= orrect?=20 Best, Efthymios Papatzikis > On 29 Jun 2024, at 07:03, Malcolm Slaney <000001757ffb5fe1-dmarc-request@xxxxxxxx= ists.mcgill.ca> wrote: >=20 > =EF=BB=BFIs there a consensus about what is the most *efficient* way to es= tablish that there is an audio-brain-recording connection?

FFRs seem intere= sting because they are continuous. ERPs seem more problematic since they of= ten have a low repetition rate.
