Abstract
WHILE we were carrying out histochemical investigations on the localization of various groups of oxidative and dephosphorylating enzymes and esterases of the olfactory bulb of the squirrel monkey (Saimiri sciurea), we noticed a Pacinian corpuscle on the olfactory bulb. This corpuscle was observed in one of our histochemical preparations of succinic dehydrogenase enzyme localization1. It was found situated at the inferior surface of the bulb between the leptomeninges covering and the nerve fibre layer (Fig. 1). It was orientated in a coronal plane to the bulb. It had a concentric lamellae of epithelial cells arranged like onion peel as observed in other Pacinian corpuscles in standard histological sections (Fig. 2). These lamellae are made up of continuous sheets of flat squamous epithelial cells laid one on top of the other, but not by fibroblasts as was once thought2–4. These cells are derived by a continuation of the perineural epithelium which covers the nerve fibre supplying the corpuscle5–12.
