Electron stereoscopy as a means of classifying synaptic vesicles

Abstract

ABSTRACT In addition to the well known ‘round’ synaptic vesicles, 2 distinct types of ‘flat’ vesicle have been found by electron stereoscopy of aldehyde-fixed central nervous tissue. In the goldfish spinal cord presynaptic terminals are found which contain cylindrical vesicles, and others which contain disk-shaped vesicles. In the rat olfactory bulb no cylindrical vesicles are found; all the flat vesicles there appear to be disk-shaped.
