Cochrane believes that this special brain bridge allows events that are perceived by one of the
twins to also travel to the brain of the other. When they appeared on a recent episode of the daytime talk show, Anderson Cooper, as Krista avidly consumed some ketchup, something she loves, Tatiana, who hates ketchup, made a horrible face.

laughing at a television program only the other could see.
