Gray code. The reflected binary code (RBC), also known as Gray code after Frank Gray, is a binary numeral system where two successive values differ in only one bit (binary digit). The reflected binary code was originally designed to prevent spurious output from electromechanical switches.
Neural tube defects happen when the neural tube does not close as expected. Anencephaly occurs when the end of the neural tube that would have developed into the brain does not close properly, resulting in the failure of the development of major portions of brain, skull and scalp.
The literal meaning of anencephaly is no brain.. But the term is not exactly accurate for. describing the condition of anencephalic babies. Such babies have no cerebrum or cerebellum but they do have a brain stem. The brain stem allows them to breathe and allows their hearts to beat. But the babies cannot see, hear, or feel anything. They will never be able to think or achieve what is called personhood..
