It’s hard enough imagining what the world would be like if you were permanently joined to another person, but what if you could also get information from their senses as well as your own?

That’s life for conjoined twins Tatiana and Krista Hogan Born on the 25th of  October 2006 to parents Felicia and Brendan Hogan of British Columbia, Canada, they are, according to their pediatric neurologist Dr. Doug Cochrane, the only known twins to have a common neurological connection.

Tatiana and Krista share parts of their brain and have a physical connection between their thalami (the thalamus is the area of the brain responsible for relaying sensation, spatial sense and motor signals to the cerebral cortex). This means that they can quiet literally see things that are in the other’s visual field.

The twins’ condition has given them very real problems. Tatiana, the smaller of the two, has an enlarged heart and actually pumps much of Krista’s blood to her brain. The complications have led to surgeries and more worries. “We just kind of live today,” said the girls’ mother Felicia. “We live within today. Forget about tomorrow, we’ll deal with tomorrow when tomorrow gets here.” For now, the girls are healthy and strong.
