These conjoined twin sisters were born fused at the head and share one brain 
Doctors were convinced they wouldn’t survive even a day, but they made it – and now they are 19 years old 
Because their brains are connected, they can feel each other’s pain, taste the food one of them eats, and even read each other’s thoughts 
How the sisters look today was shown in the first comment 
In 2006, in the Canadian province of British Columbia, an event occurred that forever changed one family’s life and sparked the interest of the global scientific community.
In the Hogan family, conjoined twin girls were born, joined at the head. They were named Tatiana and Krista.
The case was not just rare — it was unique. The girls weren’t just joined at the skull; they nearly shared a single brain.
In medical practice, this occurs in only 1 out of 2.5 million births — such twins are called “craniopagus.” Usually, these children die within the first 24 hours, and only about 20% have a chance of survival.
Tatiana and Krista passed that threshold, astonishing doctors and scientists.
Their most remarkable feature is the so-called thalamic bridge — a neural connection between the thalamus regions of their brains.
Although each girl has her own brain, the connection is so strong that separation was impossible.
This bridge gave them an incredible ability: they can feel each other’s pain, experience the taste of food one of them eats, and even sense each other’s desires.
Still, Tatiana and Krista are not one person — they are two distinct individuals. Tatiana is calmer and more thoughtful, while Krista is active, emotional, and impulsive.
Their parents did everything to give the girls the most fulfilling life possible.
They went swimming with a personal instructor, and a special bicycle was built for them, which they learned to ride with impressive skill.
They could even run by coordinating their movements and gently supporting one another.
However, there were also challenges. When it was time for preschool, it turned out not all parents were comfortable with their children interacting with such “special” twins.
Later, they attended a regular school. Due to the unique development of their brains, the girls had a slight learning delay, but they still learned to read, write, and do math.
