The voice-processing area can be taken over by visual speech-reading in poor CI users
Evidence
In contrast, Rouger et al. ( 2012 ) suggested a negative impact of cross modal plasticity: they found that the right temporal voice area (TVA) was abnormally activated in CI users by a visual speech-reading task and that this activity declined over time after implantation while the activity in Broca’s area (normally activated by speech reading) increased over time after implantation. — Dijk, Pim van, Physiology, Psychoacoustics and…, 4273
