Among other things, describes that each cell in XL OT is about 20 um in diameter.

Williamson 2018

Williamson, W. R., Peek, M. Y., Breads, P., Coop, B., & Card, G. M. (2018). Tools for Rapid High-Resolution Behavioral Phenotyping of Automatically Isolated Drosophila. Cell Reports, 25(6), 1636-1649.

[Williamson 2018] Describes some outrageously sci-fi equipment for automated tracking of fruitflies, one by one, with a dispensor, an optogenetic setup, and virtual reality dome that employes a conical mirror! Very inspiring, and also a great video-dictionary of elementary behaviors (fixed action patterns?) towards the end.

Prinz 2004

Prinz, A. A., Abbott, L. F., & Marder, E. (2004). The dynamic clamp comes of age. Trends in neurosciences, 27(4), 218-224.

A good one-paragraph summary of how injecting current in the soma is different from currents generated in the dendrites, and that it's a problem. No refs though.
