Tatiana and Krista Hogan are 4 year old twin girls who are joined at the head
. Amazingly, their brains are interconnected and share the thalamus, the section of the brain that is responsible for relaying physical sensation and motor function to the cerebral cortex. As a result, it is believed that they can experience one another’s sensations, including seeing though each other's eyes

Conjoined twins separated.
But while that operation is always challenging, this one was particularly bad. The girls were joined at the top of the head
, and their brains were merged -- and shared common blood vessels. It took eight-eight hours
of surgery to separate them, most of which was spent rerouting blood vessels. Both girls survived the operation. This is only the sixth time this operation has been attempted and only the second time that it has succeeded. (Vertical craniopagus is, mercifully, exceedingly rare.)
The operation was only possible at all because the surgeons have spent the last four months practicing it with virtual-reality software on computers (presumably using models based on MRI). Anyone have any idea what software package they used?
