Using the chronic brain recordings in the anterior cingulate cortex and orbitofrontal cortex in four participants with intractable chronic pain, this study identified objective neural biomarkers of subjective pain experience.

Increased neuronal activity and reduced sleep quality emerge in the early stages of Alzheimer’s disease (AD). Calafate et al. show that the sleep–active hypothalamic MCH system is involved in neuronal homeostasis but fails in the early stages of AD.

By reconstructing the complete dendrites and axons for nearly 2,000 neurons in PFC, Gao et al. comprehensively classified dendrite morphology, revealed the relationship between dendrites and axons and mapped the mesoscopic PFC neural network.

Using depth electrodes in human patients, scientists at the Mayo Clinic found that the map of the body in motor cortex extends deep into the central sulcus. Unexpectedly, the nonsomatotopic ‘Rolandic motor association’ (RMA) area interrupts this organization.

Hahamy et al. demonstrate that, at the transitions between narrative events, the human brain reactivates past information that is relevant for the understanding of the current narrative stage.

Reconstitution of TDP-43 filaments that exhibit sequence and morphological features similar to those found in the brain helps to uncover a new mechanism for the formation and propagation of pathology in amyotrophic lateral sclerosis and other neurodegenerative diseases.

This study tests a key hypothesis of cerebellar motor correction, showing that inputs to the cerebellum that drive errors during skilled movements are rapidly adjusted over trials to enhance motor accuracy.

Endocannabinoids are important modulators of synaptic transmission, although their mechanism of release is unknown. In this study, the authors found that endocannabinoid postsynaptic release is mediated by synucleins via a synuclein-dependent and SNARE-dependent mechanism.

By reconstructing the complete dendrites and axons for nearly 2,000 neurons in PFC, Gao et al. comprehensively classified dendrite morphology, revealed the relationship between dendrites and axons and mapped the mesoscopic PFC neural network.

Behaviors often consist of sequences of component actions. Cury and Axel identify distinct classes of sensory neurons that control the transitions between the components of egg laying in the fly that afford this behavior an adaptive flexibility.

As Nature Neuroscience celebrates its 25th anniversary, we are having conversations with both established leaders in the field and those earlier in their careers to discuss how the field has evolved and where it is heading. This month we are talking to Klaus-Armin Nave (Director at the Max Planck Institute for Multidisciplinary Sciences, Germany), a glia researcher and molecular biologist who is interested in glia–neuron interactions and a pioneer in the study of the ability of myelinating cells to metabolically support axons.

As Nature Neuroscience celebrates its 25th anniversary, we are having conversations with both established leaders in the field and those earlier in their careers to discuss how neuroscience has evolved and where it is heading. This month, we are talking to Lucina Q. Uddin, professor-in-residence at Psychiatry and Biobehavioral Sciences at the University of California Los Angeles and the 2022–2023 Chair of the Diversity & Inclusivity Committee for the Organization for Human Brain Mapping. She uses neuroimaging to study brain networks that support behavior in typically developing children and children with autism. She spoke with me about how she became interested in neuroscience, her career trajectory, and personal experiences that led to her efforts in promoting diversity, equity and inclusion.

This month, Nature Neuroscience celebrates the 25th anniversary of our first issue. To mark the occasion, we reflect on the past quarter of a century of the journal and the field, and look to the future.
