During Gastrulation, the Archenteron develops into the digestive tube, with the blastopore developing into either the mouth (Protostome) or the anus (Deuterostome).
Also primitive-the limbic system where limbic means border, edge. This includes the hippocampus, amygdala, parts of the thalamus (who knows why), some of cortex, and some other bits.
