Siamese twins, conjoined at the head, share thoughts

I've always wondered if such a thing was possible. Apparently, it is. From Gizmodo:

This is one of the most surprising and awesome tales ever told in the history of medicine. These twins are Tatiana and Krista Hogan. Their brains and sensory systems are networked together, but they have separate personalities. Their story defies belief.

So much, in fact, that Tatiana and Krista Hogan shouldn't be alive at all. Their chances of surviving the pregnancy, birth and first months of life were almost zero. Surprisingly, they turned four on October 25, and they are still healthy and happy, as you can see in the photo above.

They play Nintendo Wii games against each other, they fight for toys and they share food and physiological functions. But they also share their senses. For example, one can pick an object out of her field of view, while the twin looks at the object.

Most importantly, however, they can share thoughts.
