This study presents a valuable methodological advancement in quantifying thoughts over time. A novel multi-dimensional experience-sampling approach is presented, identifying data-driven patterns that the authors use to interrogate fMRI data collected during naturalistic movie-watching. The experimentation is inventive and the analyses carried out are convincing.

This study presents an important finding on the involvement of a Caspase 3-dependent pathway in the elimination of synapses for retinogeniculate circuit refinement and eye-specific territory segregation. This work fits well with the concept of "synaptosis" which has been proposed in the past but lacked in vivo support. Despite its elegant design and many strengths, the evidence supporting the claims of the authors is incomplete, particularly regarding whether Caspase-3 expression can really be isolated to synapses vs locally dying cells, whether microglia direct or instruct synapse elimination, and whether astrocytes are also involved. The work will be of interest to investigators studying cell death pathways, neurodevelopment, and neurodegenerative disease.

This valuable paper provides an unbiased landscape for the cerebellar cortical outputs to the brainstem nuclei. By conducting anatomical and physiological analyses of the axonal terminals of Purkinje cells, the data provide convincing evidence that Purkinje cells innervate brainstem nuclei directly. The results show that in addition to previously known inputs to vestibular and parabrachial nuclei, Purkinje cells synapse onto the pontine central grey nucleus but have little effect on the locus coeruleus and mesencephalic trigeminal neurons.

This fundamental work provides creative and thoughtful analysis of rodent foraging behavior and its dependence on body reference frame-based vs world reference frame-based cues. Compelling evidence demonstrates that a robust map, capable of supporting taking novel shortcuts, can be learned primarily if not exclusively based on self-motion cues, which has rarely if ever been reported outside of the human literature. The work, which will be of interest to a broad audience of neuroscientists, provides a rich discussion about the role of the hippocampus in supporting the behavior that should guide future neurophysiological investigations.

eLife Assessment

This work reports an important new method for activity-dependent neuronal labeling in Drosophila using in situ hybridization, with the potential to establish a new standard in the field. The authors demonstrate the method's applicability by generating compelling evidence of the function of male-specific neurons in both aggression and courtship behaviors. These results and the new method will be of great interest to the neuroscience community.

eLife Assessment

This important study addresses two questions: (i) how danger signaling is altered for people with childhood adversities, and (ii) how this differs across different operationalizations of adversity. The latter is of particularly broad interest to multiple fields, given that childhood adversity is operationalized very differently across the literature. The study provides compelling evidence using a large sample size and rigorous statistical methods. These data will be of interest to scientists and clinicians interested in early life adversity, statistical approaches for quantifying stress exposure, or aversive learning.

eLife Assessment

This important work explores the modulation of pain by intense stress. The authors employed a series of cutting-edge techniques and provided convincing evidence suggesting that the dorsal lateral septum-> lateral hypothalamus-> rostral ventromedial medulla circuit is responsible for mediating stress-induced analgesia. This work will be of interest to neuroscientists interested in the neural circuits of behavior, and scientists interested in stress or pain.

eLife Assessment

These are valuable findings for those interested in how neural signals reflect auditory speech streams, and in understanding the roles of prediction, attention, and eye movements in this tracking. However, the evidence as it stands is incomplete. Further details are needed on how the observed quantities relate to the relevant theoretical claims and mathematical models. Moreover, additional motivation is required for several analytical choices.

eLife Assessment

This study provides convincing evidence that the Kinesin protein family member KIF7 regulates the development of the cerebral cortex and its connectivity and the specificity of Sonic Hedgehog signaling by controlling the details of Gli repressor vs activator functions. This study provides important new insights into general aspects of cortical development.

eLife Assessment

This is an important study demonstrating that cholecystokinin is a key modulator of auditory thalamocortical plasticity during development and in young adults but not aged mice, though the cortical application of this neuropeptide in older animals appears to go some way to restoring this age-dependent loss in plasticity. A strength of this work is the use of multiple experimental approaches, which together provide convincing support for the proposed involvement of cholecystokinin. Nevertheless, the specificity of the electrical and optical stimulation experiments requires further validation and some key details are missing in the presentation and discussion of these findings. This work is likely to be influential in opening up a new avenue of investigation into the roles of neuropeptides in sensory plasticity.
