An olfactory sensory map in the fly brain

Article Abstract:

Research reveals 57 odorant receptor genes of Drosophila and their molecular organization in the peripheral olfactory system. Data suggest that in the insect brain a two-dimensional map of receptor activation exists mediating odor perception.

Selecting a longitudinal pathway: robo receptors specify the lateral position of axons in the Drosophila CNS

Article Abstract:

Research reveals that the short-range signal Slit can also function as long range signal and runs through receptors Rob2 and Rob3. Data indicate that expression of the receptors in the axons orient axons on to lateral position of the central nervous system of Drosophila.

Drosophila neuroblasts sequentially express transcription factors which specify the temporal identity of their neuronal progeny

Article Abstract:

Results show that Drosophila neuroblasts sequentially express the transcription factors Hunchback-Kruppel-Pdm-Castor. Data indicate that Hunchback and Kruppel specify early-born temporal identity in neuroblast cell lineages.
