One brain, two personalities?

It shows how two conjoined twins can have one brain yet two personalities, and may demonstrate how consciousness works- one brain, two psyches. Two distinct people sharing one brain.

"Brainless Boy

One related case that has received more exposure than most is that of Andrew Vandal, who was born on 12 July 1984. In the early stages of his development in the womb a cyst appeared on the stem of his brain. Known as an atelencephic aprosencephaly, this destructive event left the boy with a cranium containing nothing but fluid. In some cases, it can even leave victims with no detectible brain at all - a condition known as anencephaly or "brainlessness." Cases like Andrew's are again usually terminated before birth, but in this instance the subject was born and then put up for adoption. He was adopted by a pædiatric nurse, Kaye Vandal, from Wallingford, Connecticut, US, who, when last asked about Andrew's welfare, stated that she remained devoted to "giving him the best quality life for however long he lives." At the same time, Kaye stated that, against doctors' predictions, Andrew was able to laugh, giggle and smile and, has a "glowing, outgoing, bubbly personality." Kaye also stated that her young charge was able to respond to stimulus and was maturing mentally; both of which doctors believed to be impossible, considering his complete absence of brain matter.

Andrew was, however, unable to speak, and was cortically blind; that is, he could see images, but was unable to interpret them. Andrew was also incapable of walking, but did manage to drag himself along on his back. Cases such as Andrew's provide real-life testimony to our astonishing adaptability as biological organisms.'"
