The ability of animals to flexibly navigate through complex environments depends on the
integration of sensory information with motor commands. The sensory modality most tightly …

Publisher Summary This chapter discusses the immunocytochemical procedures used to
observe specific tissues and cells within whole-mount preparations of Drosophila embryos …

Insect dendritic arborization (da) neurons provide an opportunity to examine how diverse
dendrite morphologies and dendritic territories are established during development. We …

The small GTPases of the Rac/Rho/Cdc42 subfamily are implicated in actin cytoskeleton-
membrane interaction in mammalian cells and budding yeast. The in vivo functions of these …

The four cells of an external sense organ in the Drosophila peripheral nervous system, the
neuron, its sheath cell, and two'outer support cells” that form the hair and socket, are derived …

During development of the Drosophila peripheral nervous system, a sensory organ
precursor (SOP) cell undergoes rounds of asymmetric divisions to generate four distinct cells …

Results The Genetics of numb In an attempt to identify genes affecting neuronal
development, we have examined a collection of single P eiement-induced lethal lines …

Genetic approaches in the fruit fly, Drosophila melanogaster, have led to a major triumph in
the field of sensory biology—the discovery of multiple large families of sensory receptors …

To identify genes involved in mechanotransduction, Drosophila larvae were screened for X-
linked mutations affecting a behavioral response to touch. Many mutations that caused …

Dendrites distinguish between sister branches and those of other cells. Self-recognition can
often lead to repulsion, a process termed" self-avoidance." Here we demonstrate that …
