  This valuable study investigates the relationship between neuronal dynamics in the thalamus and brain state modulation. The claims that a specific channel is a critical player in the regulation of brain-states and ethanol-resistance in mice are supported by convincing evidence. The work will be of interest to systems neuroscientists interested in brain dynamics and behavioural states.

  This study provides a valuable description of subtypes of V1 neurons, including birthdates and connections to motor neurons. V1 neurons are one of the main groups of inhibitory neurons in the spinal cord. The methods of data collection and analysis are convincing. This work will interest developmental biologists and neuroscientists working on spinal circuits.

Astrocytes mediate two forms of spike timing-dependent depression at entorhinal cortex-hippocampal synapses

  This valuable study reports the existence of specific spike-timing dependent synaptic plasticity processes at two excitatory synapses of the dentate gyrus granule cells. These synapses link the entorhinal cortex and the dentate gyrus but via different circuits. With state-of-the-art patch-clamp electrophysiological analysis, the authors provide convincing information on the molecular mechanisms underlying these 2 forms of synaptic plasticity showing a critical role for astrocytes in both alongside some features distinctive to each pathway. These results will be of interest to neuroscientists as they uncover detailed plasticity mechanisms involving the hippocampus.

Basolateral amygdala oscillations enable fear learning in a biophysical model

  eLife Assessment

  This valuable modeling study explores how biophysical properties of different interneuron subtypes in the basolateral amygdala (BLA) enable production of oscillations that facilitate functions such as spike-timing-dependent plasticity. Simulated networks provide solid evidence that highlights the importance of interactions between interneurons for some forms of spike-timing dependent plasticity. This work will likely be of interest to investigators studying interactions among interneurons, rhythms in the amygdala, and mechanisms of plasticity thought to underlie associative learning.

  This important study demonstrated that ablation of astrocytes in the lumbar spinal cord not only reduced neuropathic pain but also caused microglia activation. The findings presented add considerable value to the current understanding of the role of astrocyte elimination in neuropathic pain, offering convincing evidence that supports existing hypotheses and insights into the interactions between astrocytes and microglial cells, likely through IFN-mediated mechanisms

Modulation of aperiodic EEG activity provides sensitive index of cognitive state changes during working memory task

  eLife Assessment

  This valuable work explores the timely idea that aperiodic activity in human electrophysiology recordings shows changes in response to task events, which may be relevant for performance, and that these changes could be misinterpreted as oscillatory changes. While it is a timely and interesting topic in principle, in the present form, the analytic approach is incomplete. Further, the data offer inadequate support for the conclusions related to theta without demonstrations that the task evokes theta power. Impressions were split, but there was consensus that the Discussion should be tempered and that revisions would improve the manuscript.

  The authors developed a method to allow a hypothermic agent, neurotensin, to cross the blood-brain barrier so it could potentially protect the brain from seizures and the adverse effects of seizures. The work is important because it is known that cooling the brain can protect it but developing a therapeutic approach based on that knowledge has not been done. The paper is well presented and the data are convincing.

  This important work presents a consolidated overview of the NeuroML2 open community standard and provides convincing evidence for its central role within a broader software ecosystem for the development of neuronal models that are open, shareable, reproducible, and interoperable. A major strength of the work is the continued development over more than two decades to establish, maintain, and adapt this standard to meet the evolving needs of the field. This work is of broad interest to the sub-cellular, cellular, computational, and systems neuroscience communities undertaking studies involving theory, modeling, and simulation.

  In this valuable paper, the authors created a reporter mouse line in which the Axon Initial Segment (AIS) is intrinsically labeled by an ankyrin-G-GFP fusion protein activated by Cre recombinase, tagging the native Ank3 gene. Using confocal, superresolution, and two-photon microscopy as well as whole-cell patch-clamp recordings in vitro, ex vivo, and in vivo, the authors convincingly document that the subcellular scaffold of the AIS and electrophysiological parameters of labeled cells remain unchanged. They further uncover rapid AIS remodeling following increased network activity in this model system, as well as highly reproducible in vivo labeling of AIS over weeks.
