Cross-modal brain plasticity from deafness variably helps or harms cochlear implant outcomes

Evidence

In summary, functional changes that occur during deafness can both enhance and degrade the ability to adapt to CI listening, perhaps depending on the communication strategy each person used while deaf. — Dijk, Pim van, Physiology, Psychoacoustics and…, 4274

• QUESTION: Which specific communication strategies (lip-reading vs sign vs speech) drive beneficial versus detrimental plasticity is left vague — a precise testable hypothesis worth chasing.
• XREF: Links to the broader debate on whether auditory deprivation plasticity is adaptive reorganization or maladaptive takeover, echoing compensation-versus-degradation debates in other sensory systems. — connects to: Late-life cochlear implants can succeed even in people deaf from birth — Eric J.
