A Neurophysiological Study of Musical Pitch Identification in Mandarin-Speaking Cochlear Implant Users

Table 5

Correlations between pitch discrimination thresholds and MMN amplitude and latency by pitch change in CI users with good and poor performance. Significant correlations () are presented in bold.
