This study identifies molecular subtypes of nucleus ambiguus neurons in adult mice and shows that Npy2r+ neurons control heart rate via the vagus nerve during diving.

This study shows that high-fat diet increases tonic GABA current in cardiac vagal motor neurons via PKCδ activity, not expression, potentially contributing to cardiovascular disease.

The paper compares the molecular and cellular organization of the superior colliculus across species, identifying conserved neuronal subtypes and synaptic genes while highlighting divergent ciliary genes and an inhibitory neuron subtype.

The paper shows that the balance of BDNF receptors TrkB and p75NTR in AgRP neurons controls PVH fiber density and stimulation-evoked feeding across different caloric states.

This study identifies SCN Neuromedin-S neurons as regulators of arousal, sleep-wake cycles, and body temperature rhythms through circuit analysis and single-nuclei RNA-Seq.

This paper shows small-molecule GLP1RAs modulate reward processing via a specific neural circuit in the central amygdala, affecting dopamine release and hedonic feeding.

The paper identifies a neural circuit involving TrhArc neurons that mediate the appetite-suppressing effects of GLP-1RAs by inhibiting AgRP neurons.

This study shows Sarm1 promotes the transition from protective to repair Schwann cell states after nerve injury, with implications for neuropathies and neurodegenerative diseases.

This study identifies 23 VLM neuron subtypes and 5 astrocyte subtypes using single-cell RNA sequencing, revealing molecular markers for breathing-related neural networks.

This study identifies that dorsal motor vagal neurons can cause bradycardia and reduce anxiety-like behavior through specific receptor mechanisms.

The paper identifies a leptin-responsive hypothalamic circuit that influences circadian feeding rhythms by modulating SCN activity and food entrainment.

The paper identifies SHH signaling from retinal ganglion cells to thalamic astrocytes as essential for GABAergic interneuron migration into the visual thalamus.

This study identifies 96 genome-wide significant loci associated with dietary intake variation using a multi-trait GWAS meta-analysis across 283,119 individuals.
