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.
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 each other thoughts, like their grandmother-Louise McKay-describes:
They share thoughts, too. Nobody will be saying anything, and Tati will just pipe up and say, ‘Stop that!' And she'll smack her sister.
Scientists are nothing short of absolutely amazed. Here you have two kids, completely different from each other, with their own distinct personality, but with connected brains and sensory systems. Dr. Douglas Cochrane-neurosurgeon at Vancouver's Children's Hospital-has tested their networking abilities:
Their brains are recording signals from the other twin's visual field. One might be seeing what the other one is seeing.
Nobody can possibly imagine how this may work and feel for them. And since they haven't developed their full verbal skills yet, scientists can't ask them about it.
