    Notes: Summary Synaptic ribbons in the pineal organ of the goldfish were examined electron microscopically with particular attention to their topography. These structures were formed of parallel membranes, which were poorly preserved with OsO4 fixation and could be extracted from thin sections with pronase indicating their proteinaceous nature. Synaptic ribbons were closely apposed to the plasma membrane bordering dendrites of ganglion cells, but were also related to processes of both photoreceptor and supportive cells. Their close proximity to invaginations of the plasma membrane and portions of the endoplasmic reticulum suggest that they are involved in the turnover of cytoplasmic membranes. Tubular and spherical organelles of unknown function are also described.

    Synaptic ribbons in the pineal organ of the goldfish: Circadian rhythmicity and the effects of constant light and constant darkness (1981)

    Notes: Summary Synaptic ribbons in photoreceptor cells of the goldfish pineal organ undergo significant daily changes in their length, distance from the plasma membrane, and number per unit area of pineal end-vesicle. The rhythms persist in fish exposed to constant darkness. Constant light abolishes the rhythms in length and distance of synaptic ribbons from the plasmalemma, but has little effect on numerical changes over a 24-h cycle. These findings suggest that synaptic ribbons in the pineal organ of lower vertebrates might be useful as indicators of metabolic activity.
