    Uniting functional network topology and oscillations in the fronto-parietal single unit network of behaving primates

    Benjamin Dann, Jonathan A Michaels ... Hansjörg Scherberger
    Oscillatory synchronized hub neurons coordinate neural network activity across multiple brain areas.

    Geometric models for robust encoding of dynamical information into embryonic patterns

    Laurent Jutras-Dubé, Ezzat El-Sherif, Paul François
    Propagation, speed and shapes of genetic waves of expression during development can be modeled by a simple interplay between two transcriptional modules (dynamic/static), which explains robustness and precision of patterning.

    A spiral attractor network drives rhythmic locomotion

    Angela M Bruno, William N Frost, Mark D Humphries
    The neural population of the Aplysia's pedal ganglion are a low-dimensional spiral attractor, and the parameters of the attractor directly define the properties of the Aplysia's escape locomotion behaviour.

    Protein gradients on the nucleoid position the carbon-fixing organelles of cyanobacteria

    Joshua S MacCready, Pusparanee Hakim ... Daniel C Ducat
    Carboxysomes, the carbon-fixation machinery of cyanobacteria, are equidistantly-positioned by dynamic gradients of the protein McdA on the nucleoid that emerge through interaction with a previously unidentified carboxysome factor, McdB.

    Risk of punishment influences discrete and coordinated encoding of reward-guided actions by prefrontal cortex and VTA neurons

    Junchol Park, Bita Moghaddam
    Risk of punishment during reward seeking behavior is associated with a functional "disconnection" of the PFC-VTA circuit due to a transient loss of VTA-driven theta oscillation.

    Impact of energy limitations on function and resilience in long-wavelength Photosystem II

    Stefania Viola, William Roseby ... A William Rutherford
    Comparisons of enzyme efficiency and electron transfer show that, to oxidize water using lower energy light, the two types of far-red photosystem II have adopted opposite trade-offs between efficiency of light use and resilience to light damage.

    Dopamine-dependent scaling of subthalamic gamma bursts with movement velocity in patients with Parkinson’s disease

    Roxanne Lofredi, Wolf-Julian Neumann ... Andrea A Kühn
    Bradykinesia in Parkinson's disease may be associated to a dopamine-dependent recruitment failure of subthalamic activity in short bursts of gamma synchrony.

    Ripples reflect a spectrum of synchronous spiking activity in human anterior temporal lobe

    Ai Phuong S Tong, Alex P Vaz ... Kareem A Zaghloul
    A continuum of ripple oscillations in human anterior temporal lobe reflects the dynamic synchrony of populations of neurons during memory retrieval.

    A balance of positive and negative regulators determines the pace of the segmentation clock

    Guy Wiedermann, Robert Alexander Bone ... J Kim Dale
    Computational modelling together with experimental manipulation indicate that the stability and turnover of activated Notch is inextricably linked to the regulation of the pace of segmentation clock gene expression in the presomitic mesoderm.

    Calmodulin-controlled spatial decoding of oscillatory Ca2+ signals by calcineurin

    Sohum Mehta, Nwe-Nwe Aye-Han ... Jin Zhang
    The ability of calcium waves to exert different effects on calcineurin activity depending on subcellular location is mediated by the distribution of calmodulin.
