Active vision and higher brain function in Drosophila melanogaster

If you have a question about this talk, please contact Greg Jefferis .

Studying how arthropods, with tiny brains, produce sophisticated behaviors could reveal new principles of nervous system function. In this talk, I will discuss a simple vision-based algorithm used by flying fruit flies to guide steering decisions. I will also describe a new preparation that allows one to perform whole-cell patch-clamp recordings in behaving Drosophila. Initial results with this preparation demonstrate that sensory responses of fly visual neurons are strongly upregulated during flight, compared to non-flight. The ability to make detailed electrophysiological measurements in behaving Drosophila promises to help unify the understanding of behavior at the gene, cell, and circuit levels.
