Erbacher et al. have used new techniques to explore the neuro-cutaneous structures of human epidermis, which is a valuable goal given the lack of in-depth studies in human skin. Human skin is less studied than rodent skin because it presents challenges in obtaining samples and finding excellent immunohistological labels. They have employed expansion microscopy and super-resolution array tomography for histological studies and have developed a human keratinocyte and human iPSC-derived sensory neuron co-culture

This important study demonstrates that the orbitofrontal cortex is causally involved in the detection of local auditory prediction errors. The methods and procedures are convincing, although the precise functional meaning of the reported effects remains to be specified. This work is of interest to neuropsychologists and cognitive neuroscientists working on the prefrontal cortex, predictive processing, auditory perception, and electrophysiology.

This paper is of interest to cell biologists studying the mechanisms of protein posttranslational modifications. The study investigates Cullin-RING ubiquitin E3 ligases (CRLs) that regulate cyclin D1 protein stability in cells by utilizing siRNA screening and ectopic expression approaches. By screening a siRNA library containing different E3 ligases, the authors identified a previously uncharacterized combination of Cullin 1-7 and associated E3 ligases (Keap1-CUL3, DDB2-CUL4A/4B, WSB2-CUL2/5, and RBX1-CUL1-7) that are important for cyclin D1 ubiquitination and proteasome-mediated degradation.

This valuable study provides solid evidence implicating two transcription factors in the development of the actin cytoskeleton that shapes the mechanosensory hair bundles of the inner ear's hair cells. The work will be of interest to biologists interested in the development and maintenance of the hair bundle, both normal or impaired. Its impact would be improved by providing a mechanistic model for the observed effects.

These authors present a powerful tool to unbiasedly identify lysosome-associated proteins in C. elegans, and they provide a compelling, in-depth assessment of how this method can be used to understand longevity pathways and identify novel proteins. Understanding lysosomal differences in specific tissues or in response to different longevity conditions are exciting as it provides new insight into how organelles could control specific homeostasis responses. This valuable tool and proteomics datasets also represent a great resource for the C. elegans community and should pry open new studies on the regulation and role of the lysosome at the organismal level.

This study examines the expression of HDAC3 within DC compartment. Taking advantage of tamoxifen inducible ERT2-cre mouse model they observe the dependency of pDCs but not cDCs on HDAC3. The requirement of this histone modifier appears to occur during development around the CLP stage. Tamoxifen treated mice lack almost all pDC besides lymphoid progenitors. RNA seq studies identify multiple DC specific target genes within the remaining pDC - using Cut and Tag technology they validate some of the identified targets of HDAC3. Taken together, this study shows the requirement of HDAC3 on pDC but not cDC, congruent with the recent findings of a lymphoid origin of pDC.

This paper studies how amacrine cells influence retinal output signals. The approach taken is unusually direct and has the potential to make important contributions to our understanding of amacrine cells, and more generally interneurons, to circuit function. The contributions of the work described, however, are limited by several key concerns. Specifically, the results rely heavily on assumptions made about how signals traverse the retina; as a result, the evidence for adequate separation of signals contributed by the amacrine cells and those from other parallel retinal pathways is incomplete.

Studies of synaptic development and plasticity in the nematode C. elegans have been limited by the difficulty of rapid, accurate assessments of synaptic structure. Here, with a series of convincing studies, the authors introduce and validate a valuable computational pipeline, "WormPsyQi," that allows rapid, reproducible quantitation of fluorescent synaptic puncta while minimizing human error and bias. The authors also describe a new set of strains carrying synaptic markers. Together, these tools should provide groups studying this model system with the ability to quantitatively characterize chemical and electrical synapses, even in densely packed regions in 3D space such as the nerve ring.

This study presents valuable findings on the relationship between prediction errors and brain activation in response to unexpected omissions of painful electric shocks. The strengths are the research question posed, as it has remained unresolved if prediction errors in the context of biologically aversive outcomes resemble reward-based prediction errors. The evidence is solid but there are weaknesses in the experimental design, where verbal instructions do not align with experienced outcome probabilities. It is further unclear how to interpret neural prediction error signaling in the assumed absence of learning. The work will be of interest to cognitive neuroscientists and psychologists studying appetitive and aversive learning.

This study conducted fMRI experiments in an inbred rat model of absence seizures. The results provide new information suggesting reduced brain responsiveness during this type of seizure. The reviewers had divergent opinions but on average thought the study was valuable and the conclusions were solid.

Birman et al. present a valuable software interface, Pinpoint, for planning anatomically precise insertions of rigid instruments (e.g., electrodes, injection needles/pipettes, fibre optic implants) into the mouse brain. The authors provide compelling evidence of the potential of this software since, it: (1) incorporates the geometrical constraints of the rig and instruments; (2) interfaces with popular manipulator systems and data acquisition software; (3) runs on any browser; and (4) allows for easy collaboration among users. Despite these exciting features, quantification of the gains in experimental efficiency and accuracy derived from Pinpoint is needed.

This report details convincing evidence that experience with multilingualism in general, and with larger phonological inventories specifically, is related to differences in the structure of the transverse temporal gyri. The project is notable for using a relatively large sample, and confirming the primary finding in a second sample. The important findings strongly point to experience-dependent plasticity related to language experience as a driver of neuroanatomy of the auditory cortex.

This study presents valuable findings that expand our view of dopamine release in different brain regions and show that dopamine release in the lateral hypothalamus is related to the activity of orexin neurons. The evidence supporting the claims of the authors is solid, although inclusion of tests that directly assess causality of the noble pathways would have been even more conclusive. The work will be of interest of neuroscientists who study the neural basis of motivation.

This valuable study introduces an innovative method for measuring interocular suppression depth, which implicates mechanisms underlying subconscious visual processing. The evidence is solid in suggesting that the new method yields provocative uniform suppression depth results across image categories that differ from conventional bCFS threshold. It will be of interest not only to cognitive psychologists and neuroscientists who study sensation and perception but also to philosophers who work on theories of consciousness.

This important study demonstrates the use of the mammalian Musashi-1 (MSI-1) RNA-binding protein as a tool for regulating gene expression in Escherichia coli. The authors provide convincing evidence that MSI-1 functions as an effective repressor of translation, and that MSI-1 can be allosterically controlled by oleic acid. This work establishes MSI-1 as a potential tool for synthetic biology applications, and the system developed here can be used for mechanistic studies of MSI-1.
