Animals can use cues to initiate task preparation and amplify relevant #sensory input, but how? This study describes a circuit whereby an attentional cue triggers #cholinergic #forebrain activity, enhancing #olfactory responses (deactivated upon task-proficiency) @PLOSBiology https://plos.io/3VnO1hT

The dorsal fan-shaped body is a neurochemically heterogeneous sleep-regulating center in Drosophila

The role of the dorsal fan-shaped body in sleep regulation in Drosophila is contested. This study shows that cholinergic neurons in the dorsal fan-shaped body play a major role in sleep modulation in this neurochemically heterogeneous sleep-regulating center in the fly brain.
