Since neurosurgeons are such individualists, there is small wonder that the presentations vary greatly.The 3 articles on anatomy and embryology of blood vessels of the brain are followed by 18 on physiology. Most of these deal with blood flow measurements in normal patients, measurements in those anesthetized with and without raised intracranial pressure, and the effects of various medications and pathologic states on cerebral flow.
