Distribution of orexinergic neurons and their terminal networks in the brains of two species of African mole rats

▶ The orexingeric system of two species of microphthalmic African mole rats is described. ▶ These mole rats show, for the most part, a typically rodent like orexinergic system, despite the greatly reduced visual system. ▶ The orexinergic terminal networks are more strongly expressed in the larger brained mole rat.
