Professorship in Experimental Neuroregeneration within SCI-TReCS The Spinal Cord Injury & Tissue Regeneration Center Salzburg is a newly founded research consortium at the Paracelsus Medical University (PMU) with the goal to develop cell-based regenerative strategies for curative therapies for spinal cord injury patients. A core group will be the Research Group of Experimental Neuroregeneration focusing on spinal cord injury research. www.pmu.ac.at/spinalcord www.pmu.ac.at/service/karriere-stellenangebote-und-ausschreibungen |

 | RESEARCH HIGHLIGHTS | Top | Spatial processing: Connecting up the grid p153 | doi:10.1038/nrn3457 The distinctive firing patterns of grid cells in the medial entorhinal cortex are dependent on excitatory inputs from the hippocampus and local connections between these cells and fast-spiking interneurons. PDF
Learning and memory: Knockout blow for 'memory molecule' p154 | doi:10.1038/nrn3441 Protein kinase Mζ (PKMζ) is thought to be essential for the maintenance of long-term potentiation (LTP) and memory, but two new studies show that mice lacking PKMζ have normal memories and can undergo normal LTP, casting doubt on the importance of PKMζ for these processes. PDF
Pain: Microglia take control in chronic pain p154 | doi:10.1038/nrn3442 Microglia activation, BDNF release and the subsequent effect on Cl- homeostasis in spinal lamina I neurons have been shown to play key parts in the hyperalgesia side effect of chronic morphine. PDF
Auditory system: Turn it up a notch p155 | doi:10.1038/nrn3447 Pharmacological inhibition of Notch signalling partially reverses hearing loss in mice by enabling the generation of new auditory hair cells in the inner ear. PDF
Development: A light touch for eye development p156 | doi:10.1038/nrn3454 A new study shows that the proper development of the vasculature of the mouse eye depends on the detection of light in the womb by fetal melanopsin. PDF
Cell biology of the neuron: Fuelling transport p156 | doi:10.1038/nrn3463 The ATP required for the fast axonal transport of vesicles may be generated by vesicle-tethered glycolytic machinery. PDF
Glia: An astrocytic generation gap p157 | doi:10.1038/nrn3446 Astrocytic Ca2+ signalling in response to neural activity only occurs in astrocytes from developing brains. PDF
Sensory processing: A gate for sensory responses p158 | doi:10.1038/nrn3455 Spontaneous, irregular cortical activity in sensory cortex may reflect top-down control of the representation of sensory stimuli. PDF
Neural circuits: Stop 'n' go p158 | doi:10.1038/nrn3456 Spiny projection neurons in the direct and indirect pathways act simultaneously to initiate movement. PDF
Learning and memory: Austerity measures for memory p159 | doi:10.1038/nrn3462 Under conditions of reduced food availability, the Drosophila melanogaster brain responds by switching from a more energy-demanding memory consolidation process involving protein synthesis to a less costly process that does not.

Axonal transport deficits and neurodegenerative diseases Stéphanie Millecamps & Jean-Pierre Julien p161 | doi:10.1038/nrn3380 Defects in axonal transport are a feature of various neurodegenerative disorders. In this article, Millecamps and Julien provide an overview of the components of the microtubule-based axonal transport system, before examining how defects in this system might cause or influence neurodegeneration in various diseases.

Long-distance retrograde neurotrophic factor signalling in neurons Anthony W. Harrington & David D. Ginty p177 | doi:10.1038/nrn3253 The distal axon and soma of a neuron may be a considerable distance apart, but they are still required to efficiently communicate with each other. In this Review, Harrington and Ginty examine how long-distance retrograde growth factor signalling is achieved between these compartments and its functions. Abstract | Full Text | PDF

Attentional enhancement of spatial resolution: linking behavioural and neurophysiological evidence Katharina Anton-Erxleben & Marisa Carrasco p188 | doi:10.1038/nrn3443 Attention can enhance performance in tasks that involve the visual system's spatial resolution. In this Review, Anton-Erxleben and Carrasco propose a framework that seeks to explain this effect and that also has implications for the representation of spatial information.

New insights into the classification and nomenclature of cortical GABAergic interneurons Javier DeFelipe, Pedro L.

Shepherd, Chet C. Sherwood, Jochen F. Staiger, Gábor Tamás, Alex Thomson, Yun Wang, Rafael Yuste & Giorgio A. Ascoli p202 | doi:10.1038/nrn3444 The classification of cortical neurons, including interneurons, remains a thorny issue in neuroscience. This Analysis article presents and tests a possible taxonomical solution for classifying cortical GABAergic interneurons based on a web-based interactive system that allows experts to classify neurons with pre-determined morphological criteria.

OPINION The inner sense of time: how the brain creates a representation of duration Marc Wittmann p217 | doi:10.1038/nrn3452 The neural mechanisms underlying the perception of duration have proved difficult to unravel and remain unclear. Here, Wittmann explores why this has been the case and presents recent theoretical developments and empirical findings indicating that 'climbing' neural activity has a central role in time perception.
