We have developed many transgenic animals which are useful for the study of neural circuitry.
1) Orexin/EGFP mice (Tg): Orexin neurons exclusively express enhanced green fluorescent protein (EGFP) under control of human prepro-orexin promoter (3.2 kb).

3) Orexin-Flippase mice (KI): Orexin neurons exclusively express Flippase recombinase and EGFP. Flippase-2A-EGFP sequence is knocked in prepro-orexin gene allele.
