Functional selectivity in sensory-deprived cortices.

In a recent study, Lomber, Meredith, and Kral (2010) investigated crossmodal reorganization in congenitally deaf cats. They demonstrated that specific regions of the auditory cortex are responsible for distinct supranormal visual performances following early auditory deprivation. These exciting results are considered in light of recently increasing research suggesting that crossmodal plasticity associated with early sensory deprivation follows organizational principles that maintain the functional specialization of the colonized brain regions.
