Neuroplasticity in congenitally deaf individuals
In this talk I will focus how the brain can plastically change as a response to congenital sensorial deprivation – and specifically in congenital deafness. In particular, I will address questions regarding 1) Whether and how the auditory cortex of the congenitally deaf processes information from the spared senses – e.g., visual input; 2) How the auditory cortex is functionally organized and what kind of representations it holds; and 3) How does that information reach the auditory cortex.
That is, the data that I will present will bring a new understanding of how neuroplasticity changes the auditory cortex (and other structures) of the congenitally deaf so that it processes information from different senses. In doing so, I will show how deep can a cortical tissue be changed – both in terms of its connectivity, representational content, and functional organization.
