Models of the Presynaptic Terminal

Abstract

The preceding three Sections have summarized many of the morphological aspects of current synaptology. In accomplishing this, the ground covered has included conventional synaptic morphology and a range of contemporary approaches to the presynaptic terminal. Dynamic approaches to presynaptic events have not been specifically mentioned, although they, too, are relevant in the context of plasticity investigations. In categorizing synaptic morphology in this way, a large range of preparative techniques has been mentioned, and reference has been made to a wide variety of presynaptic organelles. These techniques and organelles are outlined in Tables 5 and 6.
