Need info cortical mapping

[Theresa Conrad]

I am looking for information concerning cortical mapping, and the act 
that the amount of cortical area (specifically in the premotor cortex) 
dedicated to a certain body part increases with repeated usage of that 
part.  J.T. Wall wrote an article that appeared in 1988 in _Trends in 
Neurosciences_, does anyone know of more recent research?  I am 
interested in talking to someone regarding an article I am writing for an 
undergraduate magazine writing class.
