  This useful study presents a virtual reality-based contextual fear conditioning paradigm for head-fixed mice. Solid evidence supports the claim that the reported methods provide a reliable paradigm for studying contextual fear conditioning in head-fixed mice. The approach provides a way to perform multiphoton imaging of neural circuits, and other techniques that are typically performed in head-fixed animals, during behaviors that have traditionally been studied in freely moving animals.

  This comprehensive study presents important findings that delineate how specific dopaminergic neurons (DANs) instruct aversive learning in Drosophila larvae exposed to high salt through an integration of behavioral experiments, imaging, and connectomic analysis. The work reveals how a numerically minimal circuit achieves remarkable functional complexity, with redundancies and synergies within the DL1 cluster that challenge our understanding of how few neurons generate learning behaviors. By establishing a framework for sensory-driven learning pathways, the study makes a compelling and substantial contribution to understanding associative conditioning while demonstrating conservation of learning mechanisms across Drosophila developmental stages.

  This manuscript presents an important machine-learning-based approach to the automated detection of urine and fecal deposits by rodents, key ethological behaviors that have traditionally been very poorly studied. The strength of evidence for the claim is solid, showing accuracy near 90% across several contexts. Training and testing for the specific contexts used by other experimenters, however, is probably warranted to make the model most relevant to the data that may be analyzed.

Switching perspective: Comparing ground-level and bird’s-eye views for bumblebees navigating dense environments

  In this useful study, the authors tested the ability of bumblebees to use bird-view and ground-view for homing in cluttered landscapes using modeling and behavioral experiments, claiming that bumblebees rely most on ground-views for homing. However, due to a lack of analysis of the bees' behavior during training and a lack of information as to how the homing behavior of bees develops over time, the evidence supporting their claims is currently incomplete. Moreover, there was concern that the experimental environment was not representative of natural scenes, thus limiting the findings of the study.

  This translational study presents a direct cross-species comparison (between mice, rats, and humans) of choice behavior in the same perceptual decision-making task. The study is rare in opening a window on the evolution of decision-making, and the results will be important for many disciplines including behavioral sciences, psychology, neuroscience, and psychiatry. While the strength of the evidence presented is solid, the manuscript would benefit from additional information and analyses to strengthen and clarify its main conclusions.

  This study investigates how the maintenance of a spatial location in working memory affects the representation of visual information in area V4 of monkeys. As such, it is important not only for understanding vision but also for determining how working memory impacts perceptual signals and their underlying circuits. The data provide convincing evidence of a direct communication between prefrontal circuits that store spatial information and V4, which, under the current experimental conditions, manifests mainly as changes in temporal activity patterns (oscillations).

  This valuable work investigates the social interactions of mice living together in a system of multiple connected cages. It provides solid evidence for a statistical approach capturing changes in social interactions after manipulating prefrontal cortical plasticity. This research will be of broad interest to researchers studying animal social behavior.

  This important study provides insights into the role of maternal behavior in the learning and ontogeny of vocalization. It finds evidence that the maternal behavior of sac-winged bats (Saccopteryx bilineata) can influence the learned territorial songs of their pups. The behavioral analyses are convincing, using longitudinal acoustic recordings and behavioral monitoring of individual mother-pup pairs across development and multiple wild bat colonies. The work will be relevant to a broad audience interested in the evolution and development of social behavior as well as sensory-motor learning.
