Embryonic Central Nervous System Defects

Caption

This image shows an example of defects in the development of the embryonic central nervous system in stored eggs that lacked the Fmr1 gene -- stored being the key word, since un-stored eggs showed normal development. Analogous to the spinal cord, the ladder-like ventral nerve cords on the right are from stored eggs lacking in Fmr1. The image on the left is a normal ventral nerve cord with functioning Fmr1.
