Two publications, Roe et al, 1992[1] and Metin & Frost, 1989[2], describe results pertaining to the ability of a region of cortex to process information from a different sensory mode than the one that it normally does.

Specifically, they describe studies in which:

  1. input from the retinas of newborn rodents was rerouted, by surgical methods, to parts of the cortex other than the visual
  2. the rodents were allowed to mature
  3. the responses of cortical cells in the new target region to visual stimuli were assess.

Now it's 20 years later, so I'm sure there have been many others.

Something of which these publications seem to make no mention is the behavior that developed in the test subjects (eg. did they appear, from a behavioral standpoint, to be completely blind?)

Is anyone aware of any publication, relating to these studies or other, similar experiments, which addresses such questions?

  1. Roe AW, Pallas SL, Kwon YH, Sur M. 1992. Visual projections routed to the auditory pathway in ferrets: receptive fields of visual neurons in primary auditory cortex. Journal of Neuroscience, 12(9): 3651-64.
  2. Métin C, Frost DO. 1989. Visual responses of neurons in somatosensory cortex of hamsters with experimentally induced retinal projections to somatosensory thalamus. Proceedings of the National Academy of Sciences USA, 86(1): 357-361.

Have you looked at the forward citations of the articles: RPKS92 and MF89? –  Artem Kaznatcheev Sep 15 '12 at 20:31
I had read through most of the first, but only glanced at the second, one of which turns out to be what I was looking for. –  mac01021 Sep 27 '12 at 23:26

This is an example of what I was looking for. It was in the forward citations of the second paper I mentioned. So any credit that gets assigned here should go to Artem Kaznatcheev for his suggestion. It's not possible to upvote a comment, is it?

You should try and include some of the bits you found useful in the article in the answer - that would make it more useful to future visitors and preserve some of the content that you found helpful should the link disappear in future. Also, it is possible to upvote a comment, mouse-over it to see the icon :) –  Rory M Oct 8 '12 at 21:22
