  eLife Assessment

  This study provides an important contribution to our understanding of the mechanisms underlying the limited capacity to process rapid sequences of visual stimuli. It reports convincing evidence that the attentional blink affects neurally separable processes of visual detection and discrimination. The study will be of interest to neuroscientists and psychologists investigating perception and attention.

  In this work, the authors characterize the synaptic adhesion molecule RTN4RL2, demonstrating its critical involvement in the development and function of auditory synapses between inner hair cells and spiral ganglion neurons. This study is important because it offers potential insights into therapeutic strategies for hearing loss associated with synaptic dysfunction. The findings are solid, because they are supported by the use of multiple advanced techniques, including FISH and SBEM imaging.

  eLife Assessment

  This study presents a useful characterisation of the topographical organisation of the human pulvinar, an associative thalamic subregion crucial for visual perception and attention. The evidence supporting the conclusions is solid given the multimodal validation and replication across datasets, although even higher-resolution imaging data would have strengthened the study. In their revised manuscript, the authors elaborated further on the motivation for their study and conducted several robustness checks. Nevertheless, there remains an opportunity for a more fully integrated interpretation of the findings. The work would be of interest to neuroscientists, neurologists, and neuropsychiatrists working on pulvinar functioning in health and disease.

  This paper presents a valuable software package, named "Virtual Brain Inference" (VBI), that enables faster and more efficient inference of parameters in dynamical system models of whole-brain activity, grounded in artificial network networks for Bayesian statistical inference. The authors have provided solid evidence, across several case studies, for the utility and validity of the methods using simulated data from several commonly used models, but more thorough benchmarking could be used to demonstrate the reliability, generalizability, and practical utility of the toolkit. This work will be of interest to computational neuroscientists interested in modelling large-scale brain dynamics.

Cerebellar Purkinje cell stripe patterns reveal a differential vulnerability and resistance to cell loss during normal aging in mice

  This study presents valuable findings on the patterned loss of Purkinje cells in the mouse cerebellum during aging. Convincing evidence shows that Purkinje cell loss with aging occurs in a pattern of parasagittal stripes in relationship with the zebrin-II expression pattern. Further evidence supporting the Purkinje cell aging loss pattern as it relates to human cerebellar aging would strengthen the study.

  This study presents a valuable finding on how the locus coeruleus modulates the involvement of medial prefrontal cortex in set shifting using calcium imaging. The evidence supporting the claims was viewed as incomplete, although a more rigorous statistical comparison of intradimensional vs. extradimensional stages of the task, either in behavior or in the calcium imaging data, would help to address this concern. The work is of broad interest to those studying flexible cognition.

  Mackie and colleagues present a valuable comparison of lateralized gustation in two well-studied nematodes. Their results present convincing evidence that ASEL/R lateralization exists and is achieved by different means in P. pacificus compared to C. elegans. This work will be of interest to neurobiologists interested in how small nervous systems make sense of the environment, and how evolution can take multiple paths to asymmetry within a neuron class.

  eLife Assessment

  This useful study uses brain stimulation and electroencephalography to study speech-gesture integration. It investigates the role of frontotemporal regions in integrating linguistic and extra-linguistic information during communication, focusing on the inferior frontal gyrus and posterior middle temporal gyrus. Reliance on activation patterns of tightly-coupled brain regions over short timescales leads to incomplete support for the study's conclusions due to conceptual and methodological limitations.
