  This valuable study introduces a novel experimental and modeling framework to quantify passive joint torques in Drosophila, revealing that passive forces are insufficient to support body weight, contrary to prior assumptions based on larger insects. The approach is technically impressive, combining genetic silencing, kinematic tracking, and biomechanical modeling. However, the strength of evidence is incomplete, limited by concerns about the specificity of the genetic tools, simplifications in the mechanical model, and limited functional interpretation.

  This important study investigates changes in oscillatory activity across cortical and subcortical areas during stroke recovery in a nonhuman primate model. The authors distinguish between global and local oscillatory bursts, providing solid evidence that these two types of bursts correlate with distinct aspects of movement; additionally, they show that the likelihood of these bursts occurring follows opposing trends during recovery. The study could be further improved by accounting for inter-individual differences and by some technical improvements, such as employing more robust burst detection methods and more stringent analyses.

  eLife Assessment

  This is a valuable computational study of odor responses in the early olfactory system of insects and vertebrates. The study addresses the question of how information about odor concentration is encoded by second-order neurons in the invertebrate and vertebrate olfactory system; it offers insights into the transformation of neural signals from receptors to second-order neurons. While reanalysis of published data presents solid evidence supporting compression of concentration information, incomplete analysis is provided to resolve how this observation could be reconciled with the need to preserve information about changes in stimulus intensity. This work will be of interest to neuroscientists studying sensory processing broadly and olfaction specifically.
