Abstract

Summary The quantitative characterization of synapses in O sO 4- and ethanolic phosphotungstic acid acid (E-PTA)-treated nervous tissue is reinvestigated making use of recent progress an quantitative stereology. The surface area of synaptic junctions per volume and the mean length of the synaptic contact zones are introduced as parameters. It reveals that the E-PTA-stained synaptic junctions are qualitatively and quantitatively equivalent to the membrane thickenings of the O sO 4-treated synaptic contact zones. The relevance of quantitative synaptology is discussed.
