title: Electron microscopic evidence of glycogen storage in the dark pinealocytes of the rabbit pineal gland.
abstract: Electron microscopic evidence is given that the small dark granules in the rabbit dark pinealocytes represent glycogen. The conception is put forward that this glycogen, synthesized at the membranes of the rough endoplasmic reticulum, is taken up by lysosomes to participate then in the conversion of the lysosomes into pigment bodies.
