Auditory processing after transient hearing loss in adolescence

The Dan Sanes lab at New York University used NeuroNexus 64-channel Buzsaki64_5x12-H64LP_30mm and A4x16-Poly2-5mm-23s-200-177-H64LP_30mm probes to test auditory processing in adolescent gerbils subject to transient hearing loss. They used custom-mounted NeuroNexus dDrive microdrives to chronically implant the probes to span the tonotopic axis of the left core auditory cortex. Their single-unit and multi-unit recordings demonstrated that perturbation of sensory development during adolescence, separate from the earlier critical period, can cause perceptual deficits attributed to abnormal cortical function.
