    PGC-1α regulates mitochondrial biogenesis and adaptive thermogenesis. Cheng and colleagues alter the expression of PGC-1α in primary neuronal cultures and in the adult mouse brain, and find that it regulates dendritic spine formation and maintenance by mediating the synaptogenic actions of BDNF and CREB.

    Multiple sclerosis is characterized by the activation of microglia cells. Davalos et al. investigate the early stages of neuroinflammation in mice and reveal that the plasma protein fibrinogen induces microglial clustering around the brain vasculature, which facilitates lesion formation and focal axonal damage.

    Working memory is vital for individuals to carry out everyday activities. Fougnie and colleagues ask subjects to perform memory tasks and find that the precision of working memory varies independently across trials and items, which is inconsistent with the assumptions of standard models of memory.

    Dopaminergic circuits are implicated in exploratory motor behaviour and are modulated by acetylcholine. Using transgenic mouse models, Patelet al. find that loss of forebrain acetylcholine results in exaggerated dopamine efflux and hyperactivity, whereas loss of brainstem acetylcholine leads to hypoactivity.

    The Bolwig’s organ of Drosophilalarvae consists of 12 photoreceptors and is assumed to have very limited image-resolving properties. Justice and colleagues report that these larvae can recognize the motion of other larvae and that this can be replicated using a computer screen displaying images of larvae.

    Humans, with their opposable thumbs, are not the only species with tool-related morphological adaptations. This study shows that tool use in New Caledonian crows is facilitated by a straight bill, enabling a firm grip on tools, and an extremely wide binocular field, affording excellent visual feedback.

    Adult neurogenesis in the mammalian brain is implicated in the storage and processing of memories. Vivaret al.label afferents to new dentate gyrus granule cells and find that they receive direct input from the perirhinal and lateral entorhinal cortex and that these inputs enable spatial pattern separation.

    In the inner ear, sound waves produce movements in hair cell sterocilia, triggering the opening of ion channels. Hakizimana and colleagues show that the resultant currents change the length of sterocilia, and that these length changes alter the efficiency by which sound is converted into electrical signals.

    Fragile X syndrome is a major genetic cause of autism and is caused by loss of the fragile X mental retardation protein. In a mouse model of fragile X syndrome, Junget al. show that an absence of neuronal endocannabinoid signalling is responsible for the neurophysiological and behavioural defects.

    The pulvinar nucleus is involved in modulating visual information. Fischer and Whitney use brain imaging to study the pulvinar during visual attention, and find that the positions and orientations of attended objects are precisely encoded in the pulvinar, while information about ignored objects is gated out.

    Seizure activity in the brain is characterized by the recruitment of cortical neuronal activity. Schevon and colleagues study seizure activity in human subjects and find that the recruitment of neurons is hypersynchronous and that there is an intrinsic restraint on the propagation of this activity.

    The paratympanic organ in the avian middle ear is similar to the fish spiracular organ, but its developmental origin is unresolved. O'Neillet al. use fate mapping techniques to show that the avian paratympanic organ and its afferent neurons arise from a previously undiscovered neurogenic placode.

    Sex pheromones are used by adult members of a species to attract a mate. This study proposes that the larvae of the cotton leafwormSpodoptera littoralisare attracted to sex pheromones and prefer a food source containing it, suggesting an alternative use of the sex pheromone to trigger food search in caterpillars.

    The kinase PINK1 is mutated in Parkinson's disease and accumulates in defective mitochondria, where it recruits Parkin. Here, PINK1 is shown to be autophosphorylated and this is required for the localization of PINK1 to mitochondria with a reduced membrane potential, and for the recruitment of Parkin.

    Changes in gene expression in the hippocampus and the cortex are pivotal for memory consolidation. Gräff and colleagues use a recognition task in mice to show that epigenetic post-translational modifications are rapidly activated in the hippocampus after learning, but induced with a delay in the cortex.

    Cyclic nucleotide-gated channels are apparently voltage insensitive despite having the S4-type voltage sensor. Marchesiet al.show that the gating of wild-type CNGA1 and native CNG channels is voltage-independent in the presence of Li+, Na+ and K+, but that it is voltage-dependent in the presence of Rb+, Cs+ and organic cations.

    In uteroelectroporation allows the labelling of specific populations of neurons in the developing mouse brain. The authors of this paper present a simple modification of this method that increases labelling efficiency and allows, for the first time, transfection of Purkinje cells in the rat cerebellum.

    Electrical stimulation is used to treat a range of neurological diseases, but there are limitations that reduce its benefits. Bonmassar and colleagues show that magnetic stimulation delivered by small coils, close to the targeted neural tissue, can also be used to activate neurons and with fewer limitations.

    Synaptic GTPase-activating protein, SynGAP, is a postsynaptic signalling protein that can regulate synaptic function. McMahonet al. express different SynGAP isoforms in neurons and find that the effect on synaptic strength depends on alternative promoter usage and alternative splicing of the C-terminus.

    Claudin-5 is a component of tight junctions and has important roles in mediating the permeability of the blood-brain barrier. Campbell and co-workers administer short interfering RNA against claudin-5 in a model of brain injury, finding that it enhances water movement from the brain to the blood and alleviates swelling.

    Signalling inputs to neural progenitors regulate the differentiation of the stem cell pool. By analysing the mechanisms occuring during neurogenesis, Cambrayet al. report that activin is the pivotal factor regulating the differentiation of telencephalic neural precursors towards a cortical interneuron fate.

    The damaging effects of loud noise on auditory function are well established, but the effects of low-level noise are not so well understood. Zhou and Merzenich chronically expose adult rats to structured low-level noise and find that it causes auditory cortex damage and sound discrimination impairment.

    Adars are adenosine deaminases that act on RNAs, including those encoding proteins involved in neuronal transmission and also Adar RNA. Here, Savvaet al. engineered knock-in Drosophila mutants with altered Adar autoediting and found that this changed the spectrum of adenosine deamination and Drosophilabehaviour.

    Some animals find the same odorant attractive at low concentrations and repulsive at high concentrations, but how this discrimination occurs is unclear. UsingCaenorhabditis elegans as a model system, Yoshida et al. show that different sets of sensory neurons respond to low and high concentrations of odours.

    Tyrosyl DNA phosphodiesterase 1 (TDP1) repairs DNA breaks and is mutated in the disease Spinocerebellar Ataxia with Axonal Neuropathy. Here TDP1 is shown to be post-translationally modified by sumoylation of lysine 111, and cells carrying a mutation at this residue are inefficient at single-strand DNA break repair.
