Sequential progression of differentiation in a tissue or in multiple tissues in a synchronized
manner plays important roles in development. Such waves of differentiation are especially …

Visual information processing in animals with large image forming eyes is carried out in
highly structured retinotopically ordered neuropils. Visual neuropils in Drosophila form the …

The optic lobes comprise approximately halfofthe fly'sbrain. In four major synaptic ganglia, or
neuropils, the visual input from the compound eyes is received and processed for higher …

The adult Drosophila eye is such an exquisitely precise neurosensory structure that it is
often compared to a crystal. Approximately 800 individual eyes (or ommatidia) are arranged …

Understanding the molecular mechanisms that regulate formation of precise patterns of
neuronal connections within the central nervous system remains a challenging problem in …

A stepwise morphogenetic program of ceil division and cell fate determination generates the
precise neuronal architecture of the visual centers of the Drosophila brain. Here, we show …

Like other sensory systems, the visual system is topographically organized: Its sensory
neurons, the photoreceptors, and their targets maintain point-to-point correspondence in …

Drosophila eye development has been extensively studied, due to the ease of genetic
screens for mutations disrupting this process. The eye imaginal disc is specified during …

The larval and early pupal development of the optic lobes in Drosophila is described
qualitatively and quantitatively using [3 H] thymidine autoradiography on 2-μm plastic …
