Coding of odors by a receptor repertoire

Article Abstract:

A systematic analysis of how odor quality, quantity, and duration are encoded by the odorant receptor repertoire of the Drosophila antenna is provided. A multidimensional 'odor space' based on the responses of each individual receptor is constructed and find that the positions of odors depend on their chemical class, concentration and molecular complexity.

Temporal control of differentiation by the insulin receptor/Tor pathway in Drosophila

Article Abstract:

The activity of the insulin (InR)/Tor pathway is a critical control element for the timing of neuronal differentiation. The examination of InR, PI3K, PTEN, Tor, Rheb, and S6 kinase mutants demonstrates that increased InR signaling leads to precocious differentiation while decreased signaling leads to delays in differentiation.
