TY - JOUR TI - Segmentation of the chick central and peripheral nervous systems AU - Keynes, Roger AU - Cook, Geoffrey T2 - The International Journal of Developmental Biology AB - The chick embryo has provided a prominent model system for the study of segmental patterning in the nervous system. During early development, motor and sensory axon growth cones traverse the anterior/rostral half of each somite, so avoiding the developing vertebral components and ensuring separation of spinal nerves from vertebral bones. A glycoprotein expressed on the surface of posterior half-somite cells confines growth cones to the anterior half-somites by a contact repulsive mechanism. Hindbrain segmentation is also a conspicuous feature of chick brain development. We review how its contemporary analysis was initiated in the chick embryo, and the advantages the chick system continues to provide in its detailed elucidation at both molecular and neural circuit levels.
