    Microsaccadic sampling of moving image information provides Drosophila hyperacute vision

    Mikko Juusola et al.
    New experiments and theory reveal how the ability to see image details depends upon photoreceptor function and eye movements, and how fruit flies (Drosophila) see spatial details beyond the optical limit of their compound eyes.

    Cortex-wide BOLD fMRI activity reflects locally-recorded slow oscillation-associated calcium waves

    Miriam Schwalm et al.
    Locally recorded calcium events related to slow wave activity show a global cortical fMRI BOLD correlate, establishing a direct relation between a basic neurophysiological signal and the macroscopic perspective of pre-clinical fMRI.

    Behavioral-state modulation of inhibition is context-dependent and cell type specific in mouse visual cortex

    Janelle MP Pakan et al.
    The three main types of inhibitory neurons in mouse primary visual cortex respond differently to locomotion in darkness and during visual stimulation, revealing context-dependent responses to changes in behavioral state.

    Combined ALK and MDM2 inhibition increases antitumor activity and overcomes resistance in human ALK mutant neuroblastoma cell lines and xenograft models

    Hui Qin Wang et al.
    The combination of ceritinib with CGM097 demonstrates remarkable antitumor activity in TP53 wild-type neuroblastoma models with ALK aberrations and is able to overcome the resistance acquired during ceritinib treatment.

    A mutant with bilateral whisker to barrel inputs unveils somatosensory mapping rules in the cerebral cortex

    Nicolas Renier et al.
    The somatosensory cortex doesn't integrate mixed bilateral inputs, as partially uncrossing projections from the whiskers duplicates their representation by segregating lateralized inputs from each side of the head.

    Motor control of Drosophila feeding behavior

    Olivia Schwarz et al.
    The neuroanatomical and functional analysis of genetically-identified motoneurons controlling all major steps of Drosophila proboscis extension provides new insights into the architecture of a motor circuitry controlling a reaching-like behavior.
    1. Structural Biology and Molecular Biophysics

    Ribosome•RelA structures reveal the mechanism of stringent response activation

    Anna B Loveland et al.
    Cryo-EM structures of 70S•RelA ribosome complexes reveal how cognate deacyl-tRNA activates RelA.

    Place recognition using batlike sonar

    Dieter Vanderelst et al.
    Echolocating bats may recognize locations in the environment (and navigate to them) by remembering the specific echo signature of those locations.

    T-box3 is a ciliary protein and regulates stability of the Gli3 transcription factor to control digit number

    Uchenna Emechebe et al.
    The transcription and splicing factor T-box3 is present in primary cilia, regulates multiple aspects of limb development, and interacts with members of the protein complex required for the stability and processing of the Gli3 transcription factor.
