Surface view of the Drosophila compound eye. An island of discovery with respect to visual processing, neural connectivity, cell differentiation and sorting, the fruit fly eye is one of the most advanced among insects. 

42x magnification. Scanning electron micrograph.

(For aficionados, the yellow cellular component labelled here is EB1, a microtubule +-tip tracker.)

Imaged using an Olympus Fluoview 1000 in the laboratory of my gracious mentor, Dr Nick Brown (Cambridge University), with funding from the BBSRC, and gratitude to my PhD supervisor, Dr Katja Roper (MRC-LMB, Cambridge University).
