      Fleming et al sought to better understand DNAJC7's function in motor neurons as mutations in this gene have been associated with amyotrophic lateral sclerosis (ALS). Using iPSC-derived motor neurons, interactome, and transcriptomic data, they provide solid evidence that loss-of-function mutations in DNAJC7 disrupt RNA binding proteins and resistance to proteasomal stress. These important findings advance our understanding of DNAJC7 in motor neurons while providing clues to how its loss may be causal for ALS; nonetheless, the experiments were performed with a single iPSC line, while at least 3 are deemed to be required to validate the results. Furthermore, the mechanistic evidence is still incomplete with respect to how DNAJC7 mutations lead to HSF1 impaired activity, and whether it is direct or not.

      The authors made a useful finding that Zizyphi spinosi semen, a traditional Chinese medicine, has demonstrated excellent biological activity and potential therapeutic effects against Alzheimer's disease (AD). The researchers presented the effects, but the research evidence for the mechanism was incomplete. The main claims were only partially supported.

      This useful study presents a possible solution for a significant problem - that of draining vein sensitivity in functional MRI, which complicates the interpretability of laminar-fMRI results. The addition of a low diffusion-weighted gradient is presented to remove the draining vein signal and obtain functional responses with higher spatial fidelity. However, the strength of the evidence is incomplete, and most tests appear to have been done only in a single subject. Significance thresholds in presented maps are very low and most cortical depth-dependent response profiles do not differ from baseline, even in the BOLD data shown as reference. Curiously, even BOLD group data fails to replicate the well-known pattern of draining towards the cortical surface.

      In this useful study, Millard et al. assessed the effects of nicotine on pain sensitivity and peak alpha frequency (PAF). The evidence shown is incomplete to support the key claim that nicotine modulates PAF or pain sensitivity, considering the effect sizes observed. This raises the question of whether the chosen experimental intervention was the most suitable approach for investigating their research question. Nonetheless, the work can be incorporated into the literature investigating the relationship between nicotine and pain, and could be of broad interest to pain researchers.

      Du et al. present a valuable study on neural activation in medial prefrontal cortex (mPFC) subpopulations projecting to the basolateral amygdala (BLA) and nucleus accumbens (NAc) during behavioral tasks assessing anxiety, social preference, and social dominance. The study has innovative approaches and solid in vivo calcium imaging data, but the evidence linking neural physiology to behavioral outcomes is incomplete. Addressing these gaps would significantly enhance the understanding of how distinct mPFC→BLA and mPFC→NAc pathways influence anxiety, exploration, and social behaviors.

      This important study leverages the power of Drosophila genetics and sparsely-labeled neurons to propose an intriguing new model for neuronal injury signaling. The authors present convincing evidence to show that the somatic response to axonal injury can be suppressed if the injury is not complete, suggesting the presence of a new mode of injury 'integration.' While the underlying mechanism of this fascinating observation has yet to be determined, the phenomenon itself will be of broad significance in the field.

      This study reports that the RNA binding and cardiomyopathy-associated protein RBM20 is expressed in specific populations of neurons in the CNS, where it binds to and regulates the expression of synapse-related RNAs. This is an important finding because it reveals a new mechanism for gene regulation in neurons by an RNA binding protein previously studied in the heart; the authors also provide data to suggest that the mechanism by which RBM20 acts in neurons may be distinct from the splicing regulation studied in cardiac tissue. The data in support of the binding and regulation of RNAs by RBM20 is compelling, using leading edge sequencing methods to determine RNA binding profiles, and cell type specific genetics for evaluation of function.
