  • Age-related microbiome changes increase medium-chain fatty acid-producing bacteria, driving GPR84-mediated myeloid inflammation, impaired vagal signalling and hippocampal dysfunction; targeting this gut–brain pathway restores memory in aged mice.

  • Activity in a set of parabranchial neurons in the mouse brain is increased during chronic pain, predicts coping behaviour, and can be modulated by circuits activated by survival threats.

  • It is demonstrated that the brain circuitry involved in regulating the motivation for physical activity is not strictly central nervous system autonomous but is shaped by peripheral influences that originate in the intestinal microbial community.

  • Activity in anterior deep cerebellar nuclei reduces food consumption in mice without reducing metabolic rate, potentially identifying a therapeutic target for disorders involving excessive eating.

  • Cell-type-specific electrical activity manipulations and deep-brain imaging in mice of neuronal populations associated with homeostasis of nutrient or fluid intake reveals that learning is conditioned by a negative-valence signal from the hunger-mediating AGRP neurons and also from the thirst-mediating neurons in the subfornical organ.

  • The biological drive to consume salt ensures that we consume adequate sodium for survival. In this issue of Nature Neuroscience, two articles provide insight into the neurons and circuits that regulate sodium appetite.

  • Despite their discovery in the 19th century, the islands of Calleja, clusters of densely packed granule cells in the ventral striatum, remain enigmatic. This study reveals that islands of Calleja neurons are critical for grooming control in mice.

  • Using optogenetic and pharmacogenetic techniques, the authors find that AGRP neurons suppress oxytocin-releasing neurons, which is a critical interaction for evoked feeding; thus they identify a circuit potentially involved in regulating hunger state.

  • In this paper, Atasoy and colleagues use a genetically-encoded synaptic marker for electron microscopy (GESEM) to probe long-range neuronal connectivity at the nanoscale level. The authors fused the horseradish peroxidase to the vesicle-associated membrane protein 2 (VAMP2) to label synaptic vesicles. Focusing on the mouse feeding system, they show that this new tool is suitable for connectomics analyses of genetically defined populations of neurons.
