Diverse sensory organs, including mammalian taste buds and insect chemosensory sensilla, show a marked compartmentalization of receptor cells; however, the functional impact of this organization remains unclear. Here we show that compartmentalized Drosophila olfactory receptor neurons (ORNs)...

The article focuses on the study regarding the capability of Drosophila melanogaster, two-stage Hedgehog (HH) signalling to contribute to the spatial arrangement of different classes of olfactory receptor neuron (ORN) cell bodies. It notes the occurrence of HH signalling when it binds to and...

The article features the research that investigates the olfactory coding mechanisms of Drosophila in the U.S. Researchers used system identification methods to the specimen's Olfactory Sensory Neurons (OSN), applied white noise odor waveforms and recorded the response of Projection Neurons (PN)...

In Drosophila, most individual olfactory receptor neurons (ORNs) project bilaterally to both sides of the brain. Having bilateral rather than unilateral projections may represent a useful redundancy. However, bilateral ORN projections to the brain should also compromise the ability to lateralize...

Neurons have an enormous capacity to adapt to changing conditions through the regulation of gene expression, morphology, and physiology. In the fruit fly Drosophila melanogaster, this plasticity includes recurrent changes taking place within intervals of a few hours during the day. The rhythmic...

Most vertebrates have two olfactory organs, the olfactory epithelium (OE) and the vomeronasal organ. African clawed frog, Xenopus laevis, which spends their entire life in water, have three types of olfactory sensory epithelia: the OE, the middle chamber epithelium (MCE) and the vomeronasal...

Olfactory sensory neurons (OSN) in mice express only 1 of a possible 1,100 odor receptors (OR) and axons from OSNs expressing the same odor receptor converge into ∼2 of the 1,800 glomeruli in each olfactory bulb (OB) in mice; this yields a convergence ratio that approximates 2:1, 2...

Photoreceptor neurons (R cells) in the Drosophila visual system elaborate a precise map of visual space in the brain. The eye contains some 750 identical modules called ommatidia, each containing eight photoreceptor cells (R1-R8). Cells R1-R6 synapse in the lamina; R7 and R8 extend through the...

When two socially naive Drosophila males meet, they will fight. However, prior social grouping of males reduces their aggression. We found olfactory communication to be important for modulating Drosophila aggression. Although acute exposure to the male-specific pheromone 11-cis-vaccenyl acetate...
