This is a picture of chicken embryos. On the left, unoperated. The right two frames show degrees of synophthalmia and holoprosencephaly (with reduction of forebrain tissue) in cephalic neural crest-ablated subjects. The forebrain territory itself had not been operated. This demonstrates that neural crest cells are vital to the survival of the telencephalon and much of the diencephalon. The effect is a phenocopy of interfering with the Sonic hedgehog signaling cascade either through gene mutations or teratogen exposure.
