Nature Neuroscience, Published online: 16 May 2024; doi:10.1038/s41593-024-01640-4Christenson et al. describe hue-selective neurons in the fruit fly optic lobe. Using a connectomics-constrained model combined with genetic manipulations of the circuit, they show that recurrent connections are critical for hue selectivity.

Nature Neuroscience, Published online: 13 May 2024; doi:10.1038/s41593-024-01643-1Physiologically relevant stimulation of dopamine neurons does not function as a reward and does not endow cues with a reward representation. However, high-frequency stimulation is represented as a sensory-specific goal that motivates behavior.

Nature Neuroscience, Published online: 13 May 2024; doi:10.1038/s41593-024-01639-xThe subcommissural organ (SCO) is a gland in the brain, and relatively little is known about its function. Zhang et al. genetically ablated SCO cells and observed severe hydrocephalus and neuronal defects. The reintroduction of SCO-derived peptides into SCO-ablated brain...

Miao, Luo et al. show in mice that brain clearance is markedly reduced—not increased—during sleep and anesthesia.
