Venn diagram of gene populations elevated at ZT6 or ZT18 in VLPO, SCN or LH. Affymetrix GeneChip analysis resulted in populations of genes elevated in specific regions at either ZT6 or ZT18. The three common genes elevated at ZT6 were fabp7, d-albumin binding protein and an expressed sequence tag. The two common genes elevated at ZT18 were chordc1 and hsp70.
