Neuroscience

Evaluation Summary:

This manuscript features high quality experimental data with a detailed and clear analysis, combined with a neural network model to address the concept of differentiation in cerebellar functioning. This is an intensively debated topic currently and this work has an important, clear message to add to that debate. The data is very exciting, and the analyses and computational modeling very revealing and insightful. This stands on its own as a major contribution. The authors also raise an extremely interesting mechanistic interpretation of these data, which is tantalising but requires further support.

Evaluation Summary:

This paper is of interest to scientists within the field of motor learning. Converging evidence from several behavioural experiments support key claims of the paper. However, it is unclear to what degree the reported effects can be strongly linked to motor versus cognitive systems, and to what degree they novel demand revision of existing theoretical frameworks.

Evaluation Summary:

Tworig and colleagues use the mouse retina to explore the motility of Muller glial processes during development and during retinal waves that drive intracellular calcium signals in Muller glia. This is an important topic, because astrocytes in the brain have been suggested to move relative to synapses during neuronal activity. By performing careful and rigorous experiments, the authors find Muller glia processes move during development, but are not driven to move by neuronal activity. This is an important finding that will be of interest to diverse groups of readers.

Evaluation Summary:

Feedforward inhibition (FFI) typically exerts a powerful effect shaping neural activity. In this paper, Suzuki et al use a combination of in vivo and in vitro experiments to characterize, for the first time, responses in the two main classes of FFIs in the mouse olfactory cortex, neurogliaform cells (NG) and horizontal cells (HZ). They find that these two cell types have different responses and different connectivity, which partially explains their different responses. This paper also helps resolve a previously perplexing result from a recent high-profile publication that claimed that FFI in the mouse olfactory cortex appears to play a negligible role in shaping cortical odor responses, presumably because those authors were only recording from HZ cells.

Evaluation Summary:

The research conducted examines how the patterns of human eye-movements recorded during the navigation of complex mazes in immersive virtual reality relates to the computational demands of navigating the mazes. A key result is evidence of sweeps to the goal across the maze and back from the goal towards the current location prior to movement, which may help with understanding computational principles of planning. A key strength is its sophisticated computational measures for characterizing the multiple dimensions of eye movement data and the fact this work is novel with few prior studies investigating this important topic. Its findings and methodology are of interest to many areas within cognitive neuroscience, notably decision making and navigation.

Evaluation Summary:

This manuscript will be of interest to those studying the neuroscience of movement, as it addresses a fundamental aspect of movement: motoneuron recruitment. The authors provide a comprehensive analysis of motoneuron intrinsic properties that mature in the early post-natal period in mice and may lead to differentiation into "slow" and "fast" phenotypes. The authors argue that these properties, studied in spinal cord slices, contribute to motoneuron recruitment. While the study provides insights on the maturation of electrophysiological properties in motoneuron subtypes, the claims related to ionic mechanisms involved in orderly recruitment require further justification.

Evaluation Summary:

This study elucidates the molecular mechanisms whereby Gastrodia elata Blume confers neuroprotection in G2019S-induced PD models and provides a potential therapeutic treatment for PD patients. The experiments are very well designed; the images are of high-quality and convincing. The conclusions are well supported by multiple of lines of genetic and biochemical evidence. This is an important and innovative study.

Evaluation Summary:

This manuscript is of broad interest for the neuroscience and imaging community. The authors employ an array of advanced imaging techniques to bridge the understanding of neuronal function in whole organisms to the sub-cellular physiology of specific neuronal types. The microscopical observations, combined with system perturbations strongly support the claims.

Evaluation Summary:

This study examines the degree to which idiosyncrasies in visual object representations (beyond just image-driven objective representations) exist in visual areas of the brain. The authors report that later stages of the visual processing stream (specifically involving the perirhinal cortex and parts of the entorhinal cortex) do show these idiosyncratic representations, and for all levels of similarity (even for distinguishing very highly similar stimuli). These findings are interesting to vision scientists working to understand the role of different regions within the visual processing stream and to memory scientists interested in how this visual input is transformed in medial temporal lobe regions.

Evaluation Summary:

This paper is of potential interest to cognitive neuroscientists seeking to understand commonalities and differences in the neural basis of instructed and experiential reversal learning in the context of human pain. The authors report that learning from instructions versus experience leads to differences in the behavioral ratings of and the neural responses to noxious stimuli. The innovative experimental design and analyses in this study offer new perspectives on using neuro-computational models for understanding how explicitly informed vs experientially acquired information influences learning about cues predicting painful stimuli.
