  This study presents an important finding regarding how partner preference formation and pair bonding behavior are related to the oxytocin receptor gene expression in the NAc and paraventricular nucleus of the hypothalamus in prairie voles. The evidence supporting this claim is solid but could benefit from increased sample size and more thorough behavioral phenotyping. This study will be of interest to social scientists and neuroscientists who work on pair bonding and oxytocin.

  The findings in this paper provide solid support for a hypothesis that has valuable implications at the intersection of value-based and social decision-making. The findings suggest that the brain processes rewards received for effort differently when they are earned for themselves versus someone else.

  This study presents a useful array of analyses of the effects of training and/or instruction to use the method of loci during episodic encoding and retrieval. A major strength of the experiment is the impressive recruitment of memory athletes and the training of novice athletes to use the method of loci, long known to improve the precision of memory recall. That said, the sheer number of results and their organization should be addressed; streamlining the results and placing them, whenever possible, in a theoretical framework. As it stands, the presented work is incomplete with respect to the major conclusions that training itself leads to neural differentiation of prefrontal cortical neural patterns, and the authors need to temper these claims.

  This work provides a map of enhancer-promoter interactions associated with genes controlling the development of a specific neuronal cell population. The study offers a valuable resource and integrates multiple complementary datasets to provide insights into regulatory mechanisms, although the conceptual advances are moderate and the central message could be clearer. The evidence supporting the conclusions is generally solid, but the lack of direct functional testing of key regulatory elements limits the strength of some claims.

  This important study examines how chronic pain and opioid exposure interact at the cellular and molecular levels in a reward-related brain region. Using single-nucleus RNA sequencing, the authors map transcriptional changes in the rat ventral tegmental area following chronic inflammatory pain and acute morphine exposure. Notably, their convincing data support that acute morphine, not chronic pain, elicits a stress-related transcriptional response primarily in glial cells rather than neurons, challenging prevailing views of opioid action and supporting growing evidence for glucocorticoid signaling in glial responses. A limitation is the use of a single opioid dose and time point, and further discussion of these constraints would help clarify the broader implications of the findings.

Adult-neurogenesis allows for representational stability and flexibility in early olfactory system

• Curated by eLife

  eLife Assessment

  This paper presents an important theory and analysis of the role of neurogenesis and inhibitory plasticity in the drift of neural representations in the olfactory system. For one of the findings, regarding the impact of neurogenesis on the drift, the evidence remains incomplete. The reason lies in the differences in variability/drift of the mitral/tufted cell responses observed in the model compared to experimental observations, where these responses remain stable over extended time scales.

Serial dependence predicts generalization in perceptual learning

  This fundamental study describes long-range serial dependence of performance on a visual texture discrimination training task that manipulated conditions to induce differing degrees of location transfer of learning. The authors re-analyzed previously-published, behavioral data, generating compelling evidence from converging approaches that the serial dependence effects persist over multiple days of training, and may share a common causal mechanism with training-induced location transfer. By informing our understanding of the importance of temporal integration to long-term perceptual learning and its propensity towards specificity or generalizability, these results should interest neuroscientists who seek to uncover underlying neural mechanisms for these processes.

  This study provides potentially important insights by establishing a human disease model and exploring therapeutic approaches. The evidence is generally convincing for descriptive and comparative findings. The authors present solid data, but evidence for proposed biological mechanisms and functional outcomes remains limited.
