  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.

  This manuscript presents a valuable analysis of how locomotion modulates the activity of different subtypes of cortical neurons in the mouse primary visual cortex, showing that locomotion more strongly increases responses in sensitizing than in depressing excitatory cells. This data is then used to constrain a model of the responses. While the data are very interesting, the analyses remain incomplete, in particular due to concerns surrounding the modelling.
