 | | The normal ridges and valleys of the mature brain are formed after cells from the inside of the developing brain migrate to the outside and multiply. |
 | | When these cells fail to migrate, the surface remains smooth, a condition called lissencephaly ("smooth brain"). |
 | | Lissencephaly is often associated with facial abnormalities including a small jaw, a high forehead, a short nose, and low-set ears. |
