Application of the histochemical method for testing acetylcholinesterase (AChE, EC 3.1.1.7) showed the presence of AChE-positive nerve fibers in the deep pineal gland and the pineal stalk but not in the superficial part of adult albino rats. These findings may indirectly support the existence of the potentially cholinergic innervation of at least some of the rat pinealocytes present in these parts of the gland and augment the evidence of the heterogeneity of the rat pinealocytes. It is possible that cholinergic neurons in the medial habenular nuclei or in the parasympathetic sphenopalatine ganglion may be a source of these AChE-positive fibres.The examination was performed at the light microscope level.
