Globosa neurons: a distinct subgroup of noradrenergic neurons in the caudal pons of rats.
A previously undescribed subgroup of A7 neurons was identified and named globosa neurons. Morphologically, these neurons exhibit strong TH staining, are larger and globularly shaped, and are situated more laterally compared with the main group of A7 neurons. They have prominent dendritic processes that are oriented transversely and extend into the lateral lemniscus. These neurons are activated during underwater diving in rats, but at present their function is unknown.
