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.
Many sources define Schizencephaly as a very rare cortical malformation that results in grey matter-line clefts that can impact one or both sides of the brain. The brain malformation can occur during the early weeks of pregnancy.n cases involving twins, the assumption is that Schizencephaly can be due to the fact the womb was shared. Many doctors feel a stroke happens before 20 weeks gestation and account most neural tube defects on folic acid deficiency.
