This valuable study compares auditory cortex responses to sounds and cochlear implant stimulation measured with surface electrode grids in rats. Beyond the reduced frequency resolution of cochlear implants observed previously, this study suggests key discrepancies between neuronal representations of cochlear stimulations and natural sounds. However, the evidence for this potentially interesting result is incomplete because there is a lack of evidence for the effectiveness of the comparison method. This study is of interest to researchers in the auditory neuroscience field and clinicians implementing treatments with cochlear implants.
