Subject: [AUDITORY] Biological Amplifiers From: "Tejani, Viral D" <viral-tejani@xxxxxxxx> Date: Thu, 19 Jul 2018 22:54:13 +0000 List-Archive:<http://lists.mcgill.ca/scripts/wa.exe?LIST=AUDITORY>--_000_f7fb21611cf344998626c1fbcd97c3b4uiowaedu_ Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: quoted-printable Hi all, We're putting together some equipment to record acoustically evoked ECoG re= sponses from humans and animals. For the animals, we'll be recording high = frequency responses (up to 32 kHz). In the past several years, we've used an OptiAmp USB based amplifier for ou= r human work (http://www.ihsys.com/site/OptiAMP.asp?tab=3D6). Wondering if= anyone knows of anything that is more compact and portable, and that could= preferably be powered solely off of USB since we will be using a laptop to= make these measures. We would need at least a 2-channel system. Thank you for any insight. - Viral Viral Tejani, Au.D.
