Defining structural homology between the mammalian and avian hippocampus through conserved gene expression patterns observed in the chick embryo

► Identification of the origin and migration path of neurons of ventral v-shaped region of the chick hippocampus. ► Characterizing the time window and rate of cell proliferation in the chick hippocampal neurogenic zone. ► Identification of conserved gene expression patterns between the mouse and embryonic chick hippocampus. ► Defining regional homology based on gene expression patterns within the mammalian and avian hippocampus. ► Establishing the chick as a useful model system for studying avian hippocampus development.
