Glia, or glial cells, are considered a vital component of the nervous system, serving as an electrical insulator and a protective barrier from the interstitial (extracellular) media. Certain glial cells (i.e., astrocytes, microglia, and oligodendrocytes) within the CNS have been shown to directly affect neural functions, but these properties are challenging to study due to the difficulty involved with selectively-activating specific glia. To overcome this hurdle, we selectively expressed light-sensitive ion channels (i.e., channel rhodopsin, ChR2-XXL) in glia of larvae and adult Drosophila melanogaster. Upon activation of ChR2, both adults and larvae showed a rapid contracture of body wall …

With over 150,000 described species, flies constitute one of the most species-rich groups of animals on earth, and have managed to colonize almost every corner of it. Part of their success comes from their amazing flying skills, which are strongly tied to their visual capabilities. To navigate fast and accurately through their habitats, they must be able to process the inordinate amounts of visual information necessary to sort obstacles, avoid predators and remain on course. Surprisingly, despite their tiny brains, flies have no problem in processing all that information to generate correcting maneuvers in just about 30 ms. To this …
