Plasticity of claustroneocortical connections via the corpus callosum in the cat.
The cat's distribution of claustral cells that project to the contralateral visual cortex via the corpus callosum was examined. Horseradish peroxidase (HRP) was applied to severed callosal axons to label a heterogeneous population of callosal connections. Cats reared with optically induced strabismus, and Siamese cats, had HRP-filled cells extending more ventrally in the claustrum than in controls. In these groups the compaction of labeled cells was higher than in controls and the amount of increased labeled area was not dependent on the resulting eye alignment. This indicates possible plasticity of visual claustrocallosal connectivity in cats.
