Integrating new findings and examining clinical applications of pattern separation pp163 - 173 Stephanie L. Leal & Michael A. Yassa doi:10.1038/s41593-017-0065-1 The authors review the latest evidence on hippocampal pattern separation, survey recent data from cognitive tasks testing pattern separation and their application to clinical studies, and evaluate the assumptions that guide studies in the area. |

Studying and modifying brain function with non-invasive brain stimulation pp174 - 187 Rafael Polanía, Michael A. Nitsche & Christian C. Ruff doi:10.1038/s41593-017-0054-4 Polanía, Nitsche and Ruff summarize the state of non-invasive brain stimulation research in humans, discuss some current debates about properties and limitations of these methods, and give recommendations for how these challenges may be addressed. |

Hexadirectional coding of visual space in human entorhinal cortex pp188 - 190 Matthias Nau, Tobias Navarro Schröder, Jacob L. S. Bellmund & Christian F. Doeller doi:10.1038/s41593-017-0050-8 fMRI activity in human entorhinal cortex is modulated by eye-movement direction with 60° periodicity, implicating a grid cell-like code in mapping visual space. This suggests a role for entorhinal grid coding in cognition beyond spatial navigation. |

Human entorhinal cortex represents visual space using a boundary-anchored grid pp191 - 194 Joshua B. Julian, Alexandra T. Keinath, Giulia Frazzetta & Russell A. Epstein doi:10.1038/s41593-017-0049-1 The authors show that human entorhinal cortex supports a grid cell-like representation of visual space. This visual grid pattern is stably anchored to the external visual world in a fashion analogous to rodent grid representations of navigable space. |

N6-methyladenosine RNA modification regulates embryonic neural stem cell self-renewal through histone modifications pp195 - 206 Yang Wang, Yue Li, Minghui Yue, Jun Wang, Sandeep Kumar et al. doi:10.1038/s41593-017-0057-1 Using a genetic approach, Wang et al. demonstrate an essential function for m6A mRNA modification in promoting neural stem cell proliferation and reveal interactions between m6A and histone modification as a novel gene regulatory mechanism. |

Mutations in Vps15 perturb neuronal migration in mice and are associated with neurodevelopmental disease in humans pp207 - 217 Thomas Gstrein, Andrew Edwards, Anna Pristoupilová, Ines Leca, Martin Breuss et al. doi:10.1038/s41593-017-0053-5 The brain is a complex biological machine that results from the birth, migration and differentiation of neurons. This paper reports that Vps15 enables the migration and survival of neurons, and implicates the gene in neurodevelopmental disease. |

Inhibitory circuit gating of auditory critical-period plasticity pp218 - 227 Anne E. Takesian, Luke J. Bogart, Jeff W. Lichtman & Takao K. Hensch doi:10.1038/s41593-017-0064-2 The authors show that inhibitory interneurons in cortical layer 1 integrate topographically organized thalamic and neuromodulatory inputs to sculpt sound frequency maps in primary auditory cortex during a developmental critical period. |

TDP-43 pathology disrupts nuclear pore complexes and nucleocytoplasmic transport in ALS/FTD pp228 - 239 Ching-Chieh Chou, Yi Zhang, Mfon E. Umoh, Spencer W. Vaughan, Ileana Lorenzini et al. doi:10.1038/s41593-017-0047-3 Pathological TDP-43 protein aggregates are a hallmark of amyotrophic lateral sclerosis and frontotemporal dementia. TDP-43 pathology alters the morphology of nuclear pore complexes and cause deficits in nucleocytoplasmic transport. |

Dietary salt promotes neurovascular and cognitive dysfunction through a gut-initiated TH17 response pp240 - 249 Giuseppe Faraco, David Brea, Lidia Garcia-Bonilla, Gang Wang, Gianfranco Racchumi et al. doi:10.1038/s41593-017-0059-z A salt-rich diet promotes cerebrovascular diseases and dementia. This study shows that high dietary salt in mice induces a TH17 response in the gut leading to cerebral endothelial dysfunction and cognitive impairment via circulating IL-17. |

Simple integration of fast excitation and offset, delayed inhibition computes directional selectivity in Drosophila pp250 - 257 Eyal Gruntman, Sandro Romani & Michael B. Reiser doi:10.1038/s41593-017-0046-4 In the Drosophila visual system, T4 is the first cell type in the ON pathway to exhibit directionally selective signals. This directional selectivity originates from simple integration of spatially offset fast excitatory and slow inhibitory inputs. |

Dentate network activity is necessary for spatial working memory by supporting CA3 sharp-wave ripple generation and prospective firing of CA3 neurons pp258 - 269 Takuya Sasaki, Verónica C. Piatti, Ernie Hwaun, Siavash Ahmadi, John E. Lisman et al. doi:10.1038/s41593-017-0061-5 Sasaki et al. reveal that the dentate gyrus not only performs pattern separation but also has a direct role in organizing memory-guided behavior by coordinating the planning of future actions. |

Grid scale drives the scale and long-term stability of place maps pp270 - 282 Caitlin S. Mallory, Kiah Hardcastle, Jason S. Bant & Lisa M. Giocomo doi:10.1038/s41593-017-0055-3 How entorhinal grid cells control hippocampal coding and behavior remains elusive. The authors report that increasing the spatial scale of grid cells expands the scale and reduces the stability of place fields, impairing spatial memory in mice. |

Generalizable representations of pain, cognitive control, and negative emotion in medial frontal cortex pp283 - 289 Philip A. Kragel, Michiko Kano, Lukas Van Oudenhove, Huynh Giao Ly, Patrick Dupont et al. doi:10.1038/s41593-017-0051-7 Assessing person-level human brain maps across 18 fMRI studies, the authors identify separable representations of pain, cognitive control, and negative emotion in the medial frontal cortex that generalize across different studies and tasks. |

Conserved properties of dentate gyrus neurogenesis across postnatal development revealed by single-cell RNA sequencing pp290 - 299 Hannah Hochgerner, Amit Zeisel, Peter Lönnerberg & Sten Linnarsson doi:10.1038/s41593-017-0056-2 Using single-cell RNA-seq, the authors show that early developmental neurogenesis in the dentate gyrus of the hippocampus is largely conserved in the adult, but with a perinatal transformation of stem cells to an adult type. |
