One of the most important ingredients in breast milk you've never heard of

Nutrition matters, and early diet has life-long effects. So how are indigestible molecules in breast milk helping ensure the healthiest start for both breast-fed and formula-fed babies?

Review Articles

 

Investigating large-scale brain dynamics using field potential recordings: analysis and interpretation    pp903 - 919
Bijan Pesaran, Martin Vinck, Gaute T. Einevoll, Anton Sirota, Pascal Fries et al.
doi:10.1038/s41593-018-0171-8

This article presents best practices on how field potential recordings (EEG, MEG, ECoG and LFP) can be analyzed to identify large-scale brain dynamics, and highlights issues and limitations of interpretation.

Nature Spotlight on Hong Kong: Building science innovation 

Hong Kong is maximising major scientific innovation and commercial benefits through its proximity to the research and development hubs in mainland China. Yet barriers to collaboration remain.

Articles

 

Optimization of interneuron function by direct coupling of cell migration and axonal targeting    pp920 - 931
Lynette Lim, Janelle M. P. Pakan, Martijn M. Selten, André Marques-Smith, Alfredo Llorca et al.
doi:10.1038/s41593-018-0162-9

Circuit assembly relies on several developmental processes that are often considered independently. Lim and colleagues now reveal that cell migration and axon targeting may be mechanistically linked for Martinotti cells during cortical development.

 

Direct pericyte-to-neuron reprogramming via unfolding of a neural stem cell-like program    pp932 - 940
Marisa Karow, J. Gray Camp, Sven Falk, Tobias Gerber, Abhijeet Pataskar et al.
doi:10.1038/s41593-018-0168-3

Ascl1 and Sox2 convert human brain pericytes into the two major neuronal subclasses of GABA- and glutamatergic neurons. Unexpectedly, despite the lack of cell division, this conversion requires passage through a neural stem cell-like state.

 

A 3D human triculture system modeling neurodegeneration and neuroinflammation in Alzheimer’s disease    pp941 - 951
Joseph Park, Isaac Wetzel, Ian Marriott, Didier Dréau, Carla D’Avanzo et al.
doi:10.1038/s41593-018-0175-4

This study describes a 3D human neuron-astrocyte-microglia triculture model of Alzheimer’s disease using a microfluidic platform and recapitulating plaque and tangle pathology, microglial recruitment, neuroinflammation, and cell death.

 

Dorsal tegmental dopamine neurons gate associative learning of fear    pp952 - 962
Florian Groessl, Thomas Munsch, Susanne Meis, Johannes Griessner, Joanna Kaczanowska et al.
doi:10.1038/s41593-018-0174-5

Unpredicted aversive experiences activate DA neurons in dorsal tegmentum; these neurons are important for fear learning. This prediction-error circuit module linking amygdala and dorsal tegmentum enables a solution to an associative learning problem.

 

The locus coeruleus drives disinhibition in the midline thalamus via a dopaminergic mechanism    pp963 - 973
B. Sofia Beas, Brandon J. Wright, Miguel Skirzewski, Yan Leng, Jung Ho Hyun et al.
doi:10.1038/s41593-018-0167-4

Beas et al. show that stress exposure drives disinhibition of PVT projection neurons. This process involves an LC-mediated rise in extracellular DA in the midline thalamus, requires D2 receptors on PVT neurons, and increases stress sensitivity.

 

Thalamic dual control of sleep and wakefulness    pp974 - 984
Thomas C. Gent, Mojtaba Bandarabadi, Carolina Gutierrez Herrera & Antoine R. Adamantidis
doi:10.1038/s41593-018-0164-7

This study shows that tonic firing of centromedial thalamic neurons triggers rapid arousal, whereas burst firing triggers brain-wide propagating cortical slow waves and promotes sleep recovery, indicative of a midline thalamus sleep–wake hub.

 

A novel pyramidal cell type promotes sharp-wave synchronization in the hippocampus    pp985 - 995
David L. Hunt, Daniele Linaro, Bailu Si, Sandro Romani & Nelson Spruston
doi:10.1038/s41593-018-0172-7

The authors identify a CA3 new pyramidal cell type with unique morphofunctional characteristics and distinct synaptic inputs and describe how these cells contribute to sharp-wave synchronization events, which are vital to hippocampal memory function.

 

Altered hippocampal replay is associated with memory impairment in mice heterozygous for the Scn2a gene    pp996 - 1003
Steven J. Middleton, Emily M. Kneller, Shuo Chen, Ikuo Ogiwara, Mauricio Montal et al.
doi:10.1038/s41593-018-0163-8

Middleton et al. demonstrate that heterozygous deletion of the frequently mutated Scn2a gene leads to reduced performance in spatial memory tasks in mice, resulting from incomplete sequence reactivation during hippocampal sharp wave ripples.

Synaptic N6-methyladenosine (m6A) epitranscriptome reveals functional partitioning of localized transcripts    pp1004 - 1014
Daria Merkurjev, Wan-Ting Hong, Kei Iida, Ikumi Oomoto, Belinda J. Goldie et al.
doi:10.1038/s41593-018-0173-6

A localized set of mRNA at the synapse facilitates synapse formation and plasticity. The authors show an enrichment of N6-methyladenosine (m6A) modifications of these mRNA at the synapse and link m6A recognition by molecular readers to synaptic function.
