Elementary Motion Detection in Drosophila: Algorithms and Mechanisms

Annu Rev Vis Sci. 2018 Sep 15:4:143-163. doi: 10.1146/annurev-vision-091517-034153. Epub 2018 Jun 27.


Motion in the visual world provides critical information to guide the behavior of sighted animals. Furthermore, as visual motion estimation requires comparisons of signals across inputs and over time, it represents a paradigmatic and generalizable neural computation. Focusing on the Drosophila visual system, where an explosion of technological advances has recently accelerated experimental progress, we review our understanding of how, algorithmically and mechanistically, motion signals are first computed.

Keywords: Drosophila; T4; T5; direction selectivity; motion detection.
