I read about this guy a while back. Doesn’t he also have like a Masters in Math or something?
Truly remarkable. But look at some of the things they’re finding out about African Grays. And they’d think having a brain the size of a walnut would be a big step up!
The article says he has an IQ of 75. Probably doesn’t have an MA in math....
Much of the loss here seems to be in the white matter and not the gray matter. White matter is predominantly axonal tracts that tie in the different gray matter regions. So a person with this defect can think and hear and see normally or nearly so, but might have considerable difficulty in associating sensory inputs with specific memories, or in making the connections among the senses and their higher level processing in order to form those memories. So for example, a person with this kind of defect might see numbers or hear numbers spoken to him, but have difficulty in using the numbers in a math problem. On the other hand, this person might do well in math when numbers are internally generated in his mind. It is hard to predict specific behavior though just from images of the brain - this is a generalization based on anatomy. The brain is remarkable in its ability to adapt.
African Grays?
