In this useful study, Millard et al. assessed the effects of nicotine on pain sensitivity and peak alpha frequency (PAF). They propose a solid experimental framework to test the modulatory effects of nicotine on PAF and pain sensitivity, but the evidence is incomplete to support the claims that the chosen experimental intervention may actually play a significant mechanistic role in pain sensitivity given the modest effect sizes observed. The work can be incorporated into the literature investigating the relationship between nicotine and pain and could be of broad interest to pain researchers.

This computational study constitutes an extension to prior work on biophysical calcium-based synaptic plasticity rules, investigating how the regulation thresholds for strengthening and weakening connection help solve learning tasks. This important work presents a significantly simpler solution to the studied problem with potentially broad applicability, the evidence to support the core conclusions is solid.

eLife Assessment

This important study investigates how GDNF treatment restores nerve cells in the bowel of a mouse model of Hirschsprung disease, and proposes that this regeneration occurs through diverse resident precursor cells and a non-canonical signaling pathway. The evidence is solid for the ability of the treatment to induce new bowel nerve cells and for a contribution from multiple precursor populations, supported by extensive cell tracing and imaging experiments. This work will be of interest to researchers in developmental biology and peripheral neurobiology.

eLife Assessment

This work demonstrates an objective way to select parameter values for a quadratic integrate-and-fire model so that its bifurcation diagram matches a specific target diagram, generated from the Wang-Buzsaki model. The method is useful for the field and is presented with convincing evidence. The method is currently limited in its ability to be applied to data, but improves our mathematical tools to treat a rarely studied type of bifurcation.

eLife Assessment

This valuable study provides a practical computational framework for inferring latent neural states directly from calcium fluorescence recordings, bypassing the traditional need for a separate spike deconvolution step. The evidence supporting the method is convincing, featuring rigorous validation across multiple latent variable model families (including HMM, GPFA, and LFADS) using both simulated and experimental data. To further strengthen method's generality, it would require further application to a broader range of experimental datasets, such as recordings from different brain regions or using different calcium indicators.

eLife Assessment

This study presents valuable findings regarding cardiac and autonomic effects of seizures and epilepsy, with relevance to sudden unexpected death in epilepsy (SUDEP). They present solid evidence that genetic deletion of the potassium-chloride co-transporter in hypothalamic corticotropin-releasing hormone (CRH) neurons exacerbates bradycardia and enhances autonomic disturbances in a mouse model of temporal lobe epilepsy. This work will be of interest to neuroscientists working on epilepsy, the HPA axis, and autonomic control.

eLife Assessment

This study presents a fundamental molecular resource, offering subtype-specific insight into the composition of ribosome-associated protein complexes in the developing cerebral cortex. The evidence is compelling in terms of data quality and is strongly supported by the results, given the rigorous technical execution. While primarily descriptive in nature, this resource will be of great use to the field.

eLife Assessment

This important study addresses how listeners learn the statistical properties of acoustic spaces, combining well-designed psychophysics in virtual rooms with non-invasive brain stimulation. The evidence is solid: the behavioral results are strong and show that speech understanding is best in rooms with everyday levels of reverberation, and the stimulation data are consistent with a contribution of dorsolateral prefrontal cortex, though the effects are modest and the spatial precision of TMS is inherently limited. The work will be of interest to researchers in auditory neuroscience and psychoacoustics, helping to understand how the brain copes with reverberant environments.

eLife Assessment

This valuable study provides convincing evidence for deficits in aversive taste learning and taste coding in a mouse model of autism spectrum disorders. Specifically, the authors found that Shank3 knockout mice exhibit behavioral deficits in learning and extinction of conditioned taste aversion, and calcium imaging of the gustatory cortex identified impaired neuronal responses to taste stimuli. This paper will likely be of interest to researchers studying how learning and sensory processes are affected by genetic causes of autism spectrum disorders.

eLife Assessment

This important study uses diffusion magnetic resonance imaging to non-invasively map the white matter fibres connecting the zona incerta and cortex in humans. The authors present compelling evidence to indicate that these connections are organized along a rostro-caudal axis. The findings will be of interest to researchers interested in neuroanatomy and cortico-subcortical connectivity.
