  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).
