Today I learned about Krista and Tatiana Hogan who are 4 year-old twins from British Columbia who are conjoined at the head. What makes these little girls particularly interesting is that they seem to have a thin cord that connects their thalamus' together. The thalamus is the part of the brain that controls sensory input.
Scientists studying the girls believe that this may be the first case every of two people sharing a consciousness. It is hard to know for sure because the girls are too young to communicate their experiences, however, if a funny image is show to one of the girls while the other is turned away, the girl who can not see the image will also laugh. Both researchers and family members have observed the girls working together and helping one another complete tasks and make decisions without any external communication.
I also learned about the golden wheel spider who can curl up its legs and flip/roll/cartwheel away from danger. Click here to watch its awesome acrobatics.
