• Curated by eLife

  Evaluation Summary:

  Rhythmic activities play an important role in cognition and disease, and there is an increasing interest in real-time phase tracking for closed-loop applications. In this manuscript, a novel approach based on state-space modeling to estimate the phase of EEG and LFP signals in real-time is presented. Open code for distribution is readily available. The proposed model is novel, timely and makes a clear contribution to the methods base in the field.

• Curated by eLife

  Evaluation Summary:

  This paper is of broad interest to psychologists, neuroscientists, and engineers who seek to understand how color information is represented in visual cortex. The experiments provide sharply focussed tests of how chromatic information is compared across different spatial locations by individual neurons in visual cortex. The experiments are sound and the results speak to fundamental principles of encoding.

Presynaptic NMDA receptors facilitate short-term plasticity and BDNF release at hippocampal mossy fiber synapses

• Curated by eLife

  Evaluation Summary:

  This paper will be of interest to a larger neuroscience community as this is the first functional demonstration of presynaptic NMDA receptors at mossy fiber terminals in the hippocampus. NMDA receptors are generally known for being critically involved in learning & memory as coincidence detectors in Hebbian plasticity. Some studies, however, find NMDA receptors that function in more unconventional manners. The present paper provides strong evidence for the existence of such unconventional NMDA receptors at a specific subset of hippocampal mossy-fibre boutons. The combined use of electron microscopy, electrophysiological, optogenetic, calcium imaging, and genetic manipulation approaches expertly employed by the authors yields high quality compelling evidence in full support of the study's main conclusions. Overall, the investigation is well designed with a clear hypothesis, appropriate methodological considerations, and logical flow resulting in a well written manuscript that is sure to be of broad scientific interest.

Dopamine differentially modulates the size of projection neuron ensembles in the intact and dopamine-depleted striatum

• Curated by eLife

  Evaluation Summary:

  The paper is of broad interest to neuroscientists studying Parkinson's disease, dopamine (DA) modulation and striatum. The authors use a layered in vivo calcium imaging approach with cell-type reporters and universal GCaMP expression to simultaneously evaluate striatal projection neurons in the direct and indirect pathways (dSPNs, iSPNs) during basic locomotion. The authors report relationships between dSPN and iSPN ensemble sizes and DA pharmacology and dopamine depletion states. These results advance understanding of DA modulation and Parkinson's disease.

  Evaluation Summary:

  This paper sought to assess the relationship between developmental lineage and connectivity. It relies on detailed EM reconstructions and the knowledge of complete neuroblast lineages, thus correlating wiring with lineage. Through genetic manipulations of Notch function, it also correlates developmental programs with wiring. The conclusion is important and provides a well described cellular and genetic system for linking the developmental program of a cell to its connection specificity. It provides a framework for considering how to study these questions in other regions of the Drosophila brain and can be extended to the study of more complex mammalian systems where a similar neuroblast-lineage strategy generates different neuron types.
