Twins who share a brain

Twins with 1 brainThese twin girls from British Coumbia, Canada, Tatiana and Krista Hogan are Craniopagus twins.  They are thought to have the ability to see out of each others’ eyes. The Hogan twins have the ability to share senses, e.g. when you tickle one girl, the other girl laughs.

  • Krista and Tatiana were born at full-term and weighed a shared 12 lbs. 5 oz.
  • T he twins share a thalamus, the section of the brain that is responsible for relaying physical sensation and motor function to the cerebral cortex.
  • Of the twins, Krista has grown to be larger than her sister. It was discovered that Tatiana’s heart beats for the both of them, and a great deal of Tatiana’s energy is expended supporting her sister.
  • It is believed that due to the girls’ brains being connected, they can experience one another’s sensations.

    1. Saw them on Nightline last night. Really amazing how they seem to see through each other’s eyes in some way, and they feel each other’s pain, tickling, etc., and do many things in unison.

      I don’t get Nat Geo but would encourage anyone who does to tune in.
