The images depict some key molecular determinants of corticotrophin-releasing hormone (CRH) signalling in the hypothalamus of laboratory rodents and humans. In mice (left), secretagogin co-exists with neither oxytocin nor vasopressin. In contrast, a subset of vasopressin-positive and oxytocin-positive neurones can co-express secretagogin in rats (centre) and humans (right) (red, secretagogin; green, vasopressin; blue, oxytocin).
