Figure 1

Protein expression of orexin-A in prefrontal cortex. (Tissue sections were viewed at magnification.) Pale brown cells, which are positive for orexin-A expression, are oval-shaped and spread over the endochylema in the prefrontal cortex. No orexin-A positive cells were observed in the cytomembrane.
