https://doi.org/10.1007/978-3-642-96344-5This chapter describes the developmental, cellular and molecular mechanisms involved in establishing neural connectivity in the adult . visual system. It concerns itself primarily with the projections of photoreceptor axons into the optic lobe, with an emphasis on the more recent literature.

One of these is the first description of the third instar eye disc in which Weismann drew a vertical line separating a posterior domain that included a

This structure contrasts sharply with the mammalian eye, which contains a single lens and a retina with multiple layers of neurons. In spite of these and othe

Just prior to their differentiation, cells undergo an apical constriction and apical-basal contraction that produces an indentation in the disc known as the morphogen

Hardly a month goes by without a new report surfacing that describes hitherto unknown roles for the Egfr pathway in new developmental contexts. The Egfr pathway has been shown to function in (among other things) cell fa

A small number of ubiquitously expressed transcription factors combine with an even smaller number of signals emanating from the furrow and the developing clusters and generate cell-specific expression of a panoply of transcription factors (reviewed in Kumar

The function of many organs or tissues requires this additional axis of polarity within the epithelium, namely a uniform polarity of single cells or multicellular units within the plane of the epithelium.
