The field of cortical plasticity has become a very intensive field of
research recently. There was a special news article in Science about it
in October 1992. If you do a medline search for articles by Merzenich-MM,
or Kaas-JH, you'll find plenty of articles. Kaas wrote a review of the field
in the Annual Review of Neurosciences in 1991. For the latest review of the
field, you might want to refer to Sameshima and Merzenich's article published
in Current Opinion in Neurobiology in March 1993.
