Neuroplasticity, neural reuse, and the language module [article]

John Zerilli, University, The Australian National, University, The Australian National
What conception of mental architecture can survive the evidence of neuroplasticity and neural reuse in the human brain? In particular, what sorts of modules are compatible with this evidence? I aim to show how developmental and adult neuroplasticity, as well as evidence of pervasive neural reuse, forces us to revise the standard conception of modularity and spells the end of a hardwired and dedicated language module. I argue from principles of both neural reuse and neural redundancy that

In the course of doing so I articulate a schematically and neurobiologically precise framework for understanding modules and their supramodular interactions.
