[18F]FDG PET signal is driven by astroglial glutamate transport
Nature Neuroscience 20, 393 (2017).
doi:10.1038/nn.4492
Authors: Eduardo R Zimmer, Maxime J Parent, Débora G Souza, Antoine Leuzy, Clotilde Lecrux, Hyoung-Ihl Kim, Serge Gauthier, Luc Pellerin, Edith Hamel & Pedro Rosa-Neto
Contributions of glial cells to neuroenergetics have been the focus of extensive debate. Here we provide positron emission tomography evidence that activation of astrocytic glutamate transport via the excitatory amino acid transporter GLT-1 triggers widespread but graded glucose uptake in the rodent brain. Our results highlight the need for a reevaluation of the interpretation of [18F]F...

Hypothalamic CRFR1 is essential for HPA axis regulation following chronic stress
Nature Neuroscience 20, 385 (2017).
doi:10.1038/nn.4491
Authors: Assaf Ramot, Zhiying Jiang, Jin-Bin Tian, Tali Nahum, Yael Kuperman, Nicholas Justice & Alon Chen
The hypothalamic–pituitary–adrenal axis is a pivotal component of an organism's response to stressful challenges, and dysfunction of this neuroendocrine axis is associated with a variety of physiological and psychological pathologies. We found that corticotropin-releasing factor type 1 receptor within the paraventricular nucleus of the hypothalamus is an important central component of hypothalamic–pituitary–adrenal axis regulat...

The maternal 'baby brain' revisited
Nature Neuroscience 20, 134 (2017).
doi:10.1038/nn.4473
Authors: Cindy K Barha & Liisa A M Galea
Pregnancy results in changes to maternal physiology and brain that may extend into older age. New results show that pregnancy-induced reductions in gray matter volume remain 2 years after childbirth in humans. (Source: Nature Neuroscience)

New building blocks for navigation
Nature Neuroscience 20, 131 (2017).
doi:10.1038/nn.4480
Author: Jeffrey S Taube
Many spatial correlates have been identified that form the neural basis for navigation. Two studies have now uncovered a new cell type: bidirectional cells, which fire when the head is pointing in one of two opposing directions. (Source: Nature Neuroscience)

Pass the salt: the central control of sodium intake
Nature Neuroscience 20, 130 (2017).
doi:10.1038/nn.4485
Authors: Amber L Alhadeff & J Nicholas Betley
The biological drive to consume salt ensures that we consume adequate sodium for survival. In this issue of Nature Neuroscience, two articles provide insight into the neurons and circuits that regulate sodium appetite. (Source: Nature Neuroscience)

The maps they are a-changin': plasticity in odor representation in interneurons
Nature Neuroscience 20, 128 (2017).
doi:10.1038/nn.4484
Authors: Tobias Ackels & Andreas T Schaefer
Representations in excitatory neurons generally narrow as they are refined. Odor representations in interneurons, however, broaden with maturation and learning, as connections between interneurons and projection neurons expand. (Source: Nature Neuroscience)

An inhibitory pull –push circuit in frontal cortex
Nature Neuroscience 20, 389 (2017).
doi:10.1038/nn.4483
Authors: Pablo Garcia-Junco-Clemente, Taruna Ikrar, Elaine Tring, Xiangmin Xu, Dario L Ringach & Joshua T Trachtenberg
Push–pull is a canonical computation of excitatory cortical circuits. By contrast, we identify a pull–push inhibitory circuit in frontal cortex that originates in vasoactive intestinal polypeptide (VIP)-expressing interneurons. During arousal, VIP cells rapidly and directly inhibit pyramidal neurons; VIP cells also indirectly excite these pyramidal neurons via parallel disinhibition. Thus, arousal exerts a feedback pull–p...
