A spatial map of olfactory receptor expression in the Drosophila antenna
Article Abstract:
Animals are able to detect chemosensory information in the environment through an olfactory sense organ. To discriminate between various odors, the olfactory system uses odorant receptors that reside in the olfactory cilia. In the fruit fly, Drosophila, olfactory recognition is accomplished by sensory hairs on the surface of the third antennal segment and the maxillary palp. A large family of genes that are believed to be involved in the encoding of the odorant receptors of D. melanogaster are identified with the analysis of known genome sequences of the fruit fly.

Two-photon calcium imaging reveals an odor-evoked map of activity in the fly brain
Article Abstract:
Research has been conducted on odor perception logic which requires functional analysis of odor-evoked activity patterns in the brain neural assemblies. The activity in the brain neurons has been monitored with high sensitivity and good spatial resolution via the use of the developed imaging system in Drosophila brain which couples two-photon microscopy with calcium-sensitive fluorescent protein expression, and the details are reported.
