Table I.
Details of the cochlear implant users who participated in the experiments. The table shows their Patient ID (Pt ID), Date of Birth (DOB) and information for the left ear and then the right ear and finally the Time without Binaural Hearing (in years) and Time with No Hearing (in years). For the left and right, we give Etiology, Date of Deafness Onset (in years), Date of Implant Switch on (in years), Electrode used in experiments, Dynamic range of electrode (dB). The final column shows their performance in a task requiring them to discriminate between a 100-pps pulse train leading by +/−234 μs to the left vs. the right ear.
