However, the neural mechanisms underlying the effects of social rank on drug-seeking behavior remain unclear. Here we found that dominant male rodents (based on the tube test) had denser mesocortical dopaminergic projections and were more resistant to methamphetamine (METH)-seeking, whereas subordinates had heightened dopaminergic function in the mesolimbic pathway and were more vulnerable to METH seeking. Optogenetic activation of the mesocortical dopaminergic pathway promoted winning and suppressed METH seeking in subordinates, whereas lesions of the mesocortical pathway increased METH seeking in dominants. Elevation of social rank with forced win training in subordinates led to remodeling of the dopaminergic system and prevented METH-seeking behavior. In females, however, both ranks were susceptible to METH seeking, with mesocorticolimbic pathways comparable to those in subordinate males. These results provide a framework for understanding the neural basis of the impact of social status on drug-seeking.</p>","PeriodicalId":19076,"journal":{"name":"Nature neuroscience","volume":"28 1","pages":""},"PeriodicalIF":25.0,"publicationDate":"2025-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143933508","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As such, there has been a gap between these large-scale imaging techniques and the microscopic scale of mitochondrial bioenergetics. In their study published in <i>Nature</i>, Mosharov and colleagues present a method to bridge this gap by creating a spatial map of mitochondrial diversity across the brain. They cut frozen human brain tissue into 3-mm cubes, comparable in size to MRI voxels, and then registered them to MNI space. They used advanced biochemical assays to profile mitochondrial distribution and function, which were then compared with standard brain-imaging data from different modalities. The findings revealed substantial heterogeneity in mitochondrial density and oxidative phosphorylation capacity between gray and white matter. The distribution of mitochondria is suggestive of a gradient that aligns with the phylogenetic development of the brain. This study offers insight into the energetic infrastructure that supports brain function, and it has the potential to inform research into healthy brain development and disease.</p><p><b>Original reference:</b> <i>Nature</i> https://doi.org/10.1038/s41586-025-08740-6 (2025)</p>","PeriodicalId":19076,"journal":{"name":"Nature neuroscience","volume":"117 1","pages":""},"PeriodicalIF":25.0,"publicationDate":"2025-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143920805","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Connectomic analyses for subtype classification have typically been restricted to electron microscopy datasets, but the authors of a study in <i>Nature Methods</i> instead leverage high-throughput single-neuron reconstruction datasets to classify cells on the basis of potential connectivity. The authors compiled a database of over 20,000 single-neuron morphological reconstructions and used machine learning to assign topologically connected axonal and dendritic arbors. Potential connectivity was therefore obtained from the overlap of dendritic and axonal arbor spatial domains. Importantly, classification of cells based on connectivity, or c-types, outperformed classification based on morphology, or conventional m-types, and substantially contributed to classification performance jointly with m-types. Further subtyping was possible using spatially correlated connectivity and morphological features. Using c-type classification, the authors were able to showcase subtyping of thalamic and thalamocortical neurons. Potential connectivity subtyping is thus a promising method by which to classify individual neurons in the brain into types.</p><p><b>Original reference:</b> <i>Nat.

A paper published in <i>Nature</i> identifies autophagy as an important player in this phenomenon. The authors found that chronic stress in male mice downregulated autophagy in neurons in the lateral habenula (LHb) by increasing mTOR signaling. By contrast, acute stress increased autophagy in this area by increasing AMPK activation. Depression-like behavior in chronically stressed mice could be reversed or prevented by pharmacological activation of autophagy in the LHb. Various antidepressant drugs, including an mTOR inhibitor, required autophagy in this area to do their job. Autophagy mainly targeted postsynaptic glutamate receptors (GluRs) for degradation, and reduced autophagy — such as that in chronically stressed mice — was associated with excessive GluR expression and caused LHb neuron hyperactivity, impaired synaptic long-term depression, and depression-like behavior. Together, these findings show that autophagy is important for maintaining homeostasis in the LHb by counterbalancing the excessive GluRs upregulated by stress, and they suggest that restoring autophagy, possibly with an mTOR inhibitor, may be a promising target for antidepressant research.</p><p><b>Original reference:</b> <i>Nature</i> https://www.nature.com/articles/s41586-025-08807-4 (2025)</p>","PeriodicalId":19076,"journal":{"name":"Nature neuroscience","volume":"48 1","pages":""},"PeriodicalIF":25.0,"publicationDate":"2025-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143920771","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Early Notch lateral inhibition segregates DCNs into Notch<sup>ON</sup> proximally targeting axons and Notch<sup>OFF</sup> axons that adopt a bi-potential transitory state. Subsequently, probabilistic accumulation of stable microtubules in a fraction of Notch<sup>OFF</sup> axons leads to distal target innervation, whereas the rest retract to adopt a Notch<sup>ON</sup> target choice.

Across several independent samples, as well as single-echo and multi-echo functional magnetic resonance imaging (fMRI) data acquisition sequences, we identify widespread cofluctuations in the low-frequency range (0.01–0.1 Hz) between resting-state global fMRI signals, electroencephalogram (EEG) activity, and a host of peripheral autonomic signals spanning cardiovascular, pulmonary, exocrine and smooth muscle systems. The same brain–body cofluctuations observed at rest are elicited by cued deep breathing and intermittent sensory stimuli, as well as spontaneous phasic EEG events during sleep. Furthermore, we show that the spatial structure of global fMRI signals is maintained under experimental suppression of end-tidal carbon dioxide variations, suggesting that respiratory-driven fluctuations in arterial CO<sub>2</sub> accompanying arousal cannot fully explain the origin of these signals in the brain.
