Conjoined 4 year-old twins Tatiana and Krista Hogan from British Columbia, joined at the skull, may share information between their brains. 

"Their brain images reveal what looks like an attenuated line stretching between the two organs called a thalamic bridge, which may link the thalamus of one girl to the thalamus of her sister.

The thalamus is a kind of switchboard, a two-lobed organ that filters most sensory input and has long been thought to be essential in the neural loops that create consciousness. Because the thalamus functions as a relay station, the girls’ doctors believe it is entirely possible that the sensory input that one girl receives could somehow cross that bridge into the brain of the other. So if one girl drinks, the other feels it."

Doctors and scientists will study the girls as they grow and a documentary by National Geographic is underway.

Life imitates art. This was the rationale for the plot of Brain, I mean, Brian DePalma's first horror film, SISTERS from 1973, which he made between GET TO KNOW YOUR RABBIT and PHANTOM OF THE PARADISE. Margot Kidder played Danielle and Dominique.

I've never seen that one, Boris. I'll definitely check it out!
