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.

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

The inferior colliculus integrates auditory and cognitive functions, playing critical roles in sensory prediction, reward processing, and decision-making beyond its traditional role as a sensory relay.
