Auditory temporal processing in aging mice

NeuroNexus 32-channel linear probes (e.g., A1x32-mm-6mm-100-177) were inserted vertically into the inferior colliculus (IC) of aged CBA/J and C57BL/6 mice ranging from 2 or 3 months to 24 months. The 3.1mm coverage of the probes’ electrode sites spanned the full IC, and probes were cleaned and re-used for multiple penetrations. Recordings during auditory tests parse out the effects of central versus peripheral auditory deficits on temporal processing as a model of speech processing.
