We hypothesize neuroplasticity in central auditory pathways play a key role in cochlear implant outcomes. Following initial cochlear implant activation, we track psychophysical abilities (spectral discrimination) in both adult-deafened humans and rats and relate these measures to speech perception (humans) and sensory encoding in the auditory cortex (A1, rats).In humans, we sent newly implanted subjects (N=3) home with a tablet and tracked spectral (quick-spectral modulation detection, QSMD) and temporal acuity (modulation-detection test, MDT). Speech perception was tested in-lab (CNC 30). Ove
