Their brains are connected

Fascinating article about 4-year old craniopagus twins:

They are the rarest of the rarest of the rare. Tatiana and Krista are not just conjoined, but they are craniopagus, sharing a skull and also a bridge between each girl’s thalamus, a part of the brain that processes and relays sensory information to other parts of the brain. Or perhaps in this case, to both brains. There is evidence that they can see through each other’s eyes and perhaps share each other’s unspoken thoughts. And if that proves true, it will be the rarest thing of all. They will be unique in the world.

They have been drawing international attention, both public and scientific, since before their birth. Dr. Douglas Cochrane, a neurosurgeon at Children’s Hospital, is part of the team that has been watching over them since they were in the womb. Last year he conducted tests in which one twin looked at an object while he measured the brain activity in the other. “Their brains are recording signals from the other twin’s visual field,” he cautiously concluded. “One might be seeing what the other one is seeing.”

It's so sad they have so many health and developmental issues. I wonder if they can help teach us how brains can connect on a neuronal level to other things. I hope they are happy. Sorta puts my own special needs kid difficulties in perspective.
