Twin girls conjoined at the skull have remarkably defied doctors’ expectations and at seven years old share emotions and sensations and can see through each other’s eyes.
When Tatiana and Krista Hogan were born, doctors told their parents they would not survive that day But the twins are astonishingly still alive and living happy, fulfilling lives as young children.
The sisters, whose brains are locked together, can see through each other’s eyes and feel the same sensations and emotions. While they have independent use of their limbs, they can control each other’s arms and legs.
Their family believes that this brain connection has allowed the pair to communicate with each other in their own heads, citing how the twins can share a joke without even speaking.
Since their brains are linked the two cannot ever be separated.
"People always ask when will they be separated but they won't be," said their grandmother, Louise McKay. "They have too much wiring going to each other for them ever to be separated."
Yet despite this common biological link, the twins have very different personalities.
“Over the years Tatiana has become the prominent leader,” said their mother, Felicia Hogan. "Krista is quieter and can be more in her own shell.”
Doctors expected the two would be lying on their backs for the rest of their lives, but they now live life as normal kids free to play, run and even fight with each other.
“They have amazed me,” said Dr Douglas Cochrane, a neurosurgeon who has treated the girls. “How they are the same but how they are different, how they are dealing with an error of nature to live healthy lives.”
