Subject: Wireless electrophysiology technique question. From: Jazz <jazz_bailey@xxxxxxxx> Date: Thu, 22 Oct 2009 13:27:07 -0700 List-Archive:<http://lists.mcgill.ca/scripts/wa.exe?LIST=AUDITORY>Hi, I am setting up some awake behaving bats and gerbils and am using head mounted microdrive with tetrodes (made in house (1.5g)) and a tether. I am recording auditory responses from the amygdala in these animals. I have some movement noise at the moment as I don’t have a commutator, I am reluctant to buy one as they can be noisy (sound noise not electrical noise) in higher frequencies, which is bad for both the mice and the bats. I am however toying with the idea of going wireless. TBSI make a 16 channel wireless headstage that is pretty small (3g), has anyone used it? Does anyone know if there any drawbacks to using wireless systems? Or know of a commutator for small animals that is quiet across frequencies? Thanks for your help Jazz Grimsley
