Abstract
We have identified a set of larval neurones in the developing adult optic lobes of Drosophila by selectively labelling cells that have undergone only a few mitoses. A cluster of three cells is located in each of the optic lobes near the insertion site of the optic stalk. Their axons fasciculate with fibres of the larval optic nerve, the Bolwig’s nerve, and then form part of the posterior optic tract. These cells are likely to be first order inter neurones of the larval visual system. Unlike the Bolwig’s nerve, they persist into the adult stage. The possibility of a pioneering function of the larval visual system during formation of the adult optic lobe neuropil is discussed.This publication has 28 references indexed in Scilit:
