Intrinsic forces alone are sufficient to cause closure of the neural tube in the chick.
An isolated neural plate or a postnodal piece of early chick embryos, when cultured under appropriate experimental conditions, can undergo morphogenetic movements and form tubular structures closely resembling neural tubes of early chick embryos.
