Subject: [AUDITORY] Neurocontrol of auditory rehabilitation device using efferent MOC action potentials From: Jonathan Sivan <jonathan.sivan@xxxxxxxx> Date: Tue, 14 Mar 2017 15:21:47 +0200 List-Archive:<http://lists.mcgill.ca/scripts/wa.exe?LIST=AUDITORY>--001a1146cf46c25bac054ab0b52c Content-Type: text/plain; charset=UTF-8 Dear List, Extant *passive* cochlear implant electrodes could detect action potentials originating in the efferent Medial Olivocochlear (MOC) fibers. In healthy ears the efferent MOC modulates cochlear functioning; when the MOC is damaged, speech comprehension drops - especially in noise. I have in mind a proof-of-concept experiment to demonstrate that MOC action potentials can be harnessed to control a hearing rehabilitation device in the contralateral ear - to deliver speech comprehension in noise that is superior to that of current digital devices. A senior researcher of a Cochlear Implant manufacturer is willing to provide the necessary interface and cooperation to a principle investigator who would accompany the experiment through the IRB to completion. Apart from the significant clinical benefit, monitoring of such a device would have relevance for researchers interested in auditory and cognitive plasticity, attention, closed-auditory-loop, signal processing strategies & etc. I am now searching for a researcher willing to undertake the project as principle investigator - using myself as a subject. For a full presentation, including the experiment proposal, see cincard.wordpress.com. If this project interests you please do contact me and/or distribute this to anyone who might be interested.
