A Drosophila olfactory circuit exhibits experience-dependent glial pruning during a well-defined critical period, with long-term consequences for odor processing.

The opposing dopamine receptors Dop1R1 and Dop2R are both enriched around the pre- and postsynaptic sites of different types of neurons, including dopaminergic neurons, in the fly brain.

An in vivo electrophysiology approach identifies an incretin-like effect in Drosophila insulin-producing cells, highlighting key circuit dynamics which govern glucose homeostasis via conserved mechanisms.
