The paper identifies a novel pacemaker activity in Drosophila midgut called superstalsis, linked to specific muscle activation and gene expression under physiological conditions.

The paper identifies an inhibitory feedback circuit in Drosophila that links sensory processing during wakefulness to sleep need and nocturnal sleep.

The paper shows that inducing backward movement in Drosophila engages dopaminergic punishment and supports aversive memories, explaining the avoidance paradox.

The paper shows that dopamine reduces threat perception in male Drosophila during courtship, prioritizing mating over survival as courtship progresses.

The paper proposes a network model that learns accurate path integration in the Drosophila head direction system using a biologically plausible learning rule guided by supervisory cues.

The paper shows how coherent neural oscillations in Drosophila create filters that promote quiescence over navigation by hierarchically overriding locomotion-promoting networks.

This study shows that postsynaptic plasticity at cholinergic synapses in Drosophila mushroom bodies is essential for appetitive memory induction but not aversive memories.

The paper identifies delta oscillations in Drosophila's R2 network that regulate sleep, showing synchronization depends on NMDARs and input pathways, and disrupting this mechanism abolishes oscillations and impairs sleep.

The paper identifies a molecular mechanism for presynaptic plasticity involving rapid remodeling of active zone modules, which sustains neurotransmitter release potentiation over time.
