The ultrastructural interactions of identified pre- and postsynaptic cells during synaptic target recognition in Drosophila embryos.

During the development of neural networks, what sets synaptogenic interactions apart from nonsynaptogenic interactions is not well understood at the subcellular level. Using a combination of intracellular dye injection and electron microscopy, we show that a specific motoneuron (RP3) and its synaptic partners (muscles 6 and 7), both often bearing… CONTINUE READING
