Introduction to the principles by which the neural tube (brain and spinal cord) forms during embryonic development. Discuss the cellular and molecular mechanisms underlying the formation of a three-dimensional neural tube and its division into forebrain, midbrain, hindbrain, and spinal cord. Only one of the following may be counted: Biology 367C, Neuroscience 367C, Molecular Biosciences 367C. Three lecture hours a week for one semester.
