Craniopagus twins are conjoined twins that are fused at the cranium. There are one in 2.5 million people who have this rare condition. Sadly, the vast majority of twins born do not survive 24 hours.
Krista and Tatiana Hogan were born in October in 2006. Their brains are connected by a thalamic bridge and this makes them unique in every way. They share the senses of touch, taste and even control of one another’s limbs. Tatiana can see out of both of Krista’s eyes. She can also control three arms and a leg. Krista can only see out of one of Tatiana’s eyes and can control three legs and one arm.
What is even more remarkable is that the twins also have self-control of their limbs and can switch between their sensory and motor signals as they wish. Due to their phenomenal thalamic connection, the twins can never be separated as the risk of death is very high.
Though the twins say that they know one another’s’ thoughts and can take control of each other’s limbs, they have very different personalities. Tatiana is chatty and outgoing, whereas, Krista is often quiet and more relaxed.
