Subject: Re: [AUDITORY] Cortical sources of the auditory steady state response From: Malina Szychowska <mszychowska@xxxxxxxx> Date: Wed, 22 Jan 2020 15:43:26 +0100 List-Archive:<http://lists.mcgill.ca/scripts/wa.exe?LIST=AUDITORY>--00000000000086f30b059cbb8fbe Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable Dear Jacques, and the whole list It seems like the 60/80 Hz you wrote about is the FFR. I am not sure, but the way I understand the literature is that the ASSRs are not really the same thing as FFR. The FFR is the response to the base frequency of the signal, whereas ASSRs follow the envelope (or amplitude modulation, or click rate, etc). Is my understanding incorrect? This is a very interesting topic to me so I would like to know if I got that correctly or not :) Best wishes Malina =C5=9Br., 22 sty 2020 o 06:15 Jacques Pesnot <jacques.pesnot@xxxxxxxx> napisa=C5=82(a): > > Dear Ani Patel, > > We have one recent paper - not accepted yet - with B.
