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

["Dr. Efthymios Papatzikis" <efp331@xxxxxxxxxxxxxxxx>]

Dear Malcom,

ABR is a form of measuring audio perception in general at the level of the brainstem, so If you are interested to see someone’s ability to hear/perceive audio in general, yes that’s the case. However, I do not know of any way measuring different sources of audio vs silence let’s say (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 not possible because ABR is already feeding the auditory system with audio at the time of recording. You may be able to perform some monaural/binaural/masking protocols with ABR but I do not think this is what you are looking for, correct? 

Best,
Efthymios Papatzikis
