- •
Post-deafness, the auditory FAES cortex functionally reorganizes to respond to the remaining sensory modalities.
- •
This crossmodal plasticity MAY result from ingrowth of novel connections OR the unmasking of existing inputs.
- •
Compared with hearing controls, new sources of inputs to deaf FAES were not identified.
- •
Inputs to deaf FAES from other auditory cortices were maintained, not reduced.
- •
Crossmodal plasticity in deaf FAES results from multiple factors including unmasking and crossmodal signals from ‘auditory’ sources.
