He also found that ablating either the corpus callosum or the optic chiasm before
training did not interfere with transfer. However, he found that ablating both the
corpus callosum and the optic chiasm before training eliminated interhemispheric
transfer. Thus, ablating the corpus callosum and the optic chiasm had in essence
created two separate brains with no exchange of information between them. For
example, when an animal’s brain was split in the manner just described and it was
taught to make a visual discrimination with a patch over one eye, it had no
recollection of that learning when tested with the other eye (Sperry, 1961, 1964).
A brain that has had its corpus callosum and its optic chiasm ablated is referred to
as a split-brain preparation.
