    β-cell intrinsic dynamics rather than gap junction structure dictates subpopulations in the islet functional network

    Jennifer K Briggs, Anne Gresch ... Richard KP Benninger
    The functional network of β-cells in the pancreatic islet, which has been used to identify important subpopulations of β-cells implicated in diabetes progression, is indicative of intrinsic dynamics rather than structural communication, implying islet robustness.

    Topographic gradients of intrinsic dynamics across neocortex

    Golia Shafiei, Ross D Markello ... Bratislav Misic
    Intrinsic dynamics are shaped by the intersection of molecular, microstructural, connectomic, and activation gradients.

    Extrinsic and intrinsic dynamics in movement intermittency

    Damar Susilaradeya, Wei Xu ... Andrew Jackson
    The rhythmicity in upper-limb tracking movements and associated population dynamics in primary motor cortex is explained by a feedback controller incorporating optimal state estimation.

    Regulation of branching dynamics by axon-intrinsic asymmetries in Tyrosine Kinase Receptor signaling

    Marlen Zschätzsch, Carlos Oliva ... Bassem A Hassan
    Asymmetric localization of the receptor EGFR within branches of axons is required to establish the precise wiring of neuronal networks within the Drosophila brain.

    Pathway dynamics can delineate the sources of transcriptional noise in gene expression

    Lucy Ham, Marcel Jackson, Michael PH Stumpf
    There are fundamental limits to what can be learned about the origins of transcriptional noise from gene expression data alone, which can be overcome by simultaneously quantifying the abundances of linked molecular species.

    Intrinsic dynamics of randomly clustered networks generate place fields and preplay of novel environments

    Jordan Breffle, Hannah Germaine ... Paul Miller
    Computational simulations and data analysis show that random clustering in the connections of neurons receiving minimal external cues can generate place fields and their spontaneous activation in trajectory-like sequences.

    Target cell-specific synaptic dynamics of excitatory to inhibitory neuron connections in supragranular layers of human neocortex

    Mean-Hwan Kim, Cristina Radaelli ... Ed Lein
    Electrophysiological study in human brain slices reveals that short-term synaptic plasticity from presynaptic pyramidal neuron to postsynaptic interneuron connections are target-cell specific based on their subclass interneuron identity.

    Integrative dynamic structural biology unveils conformers essential for the oligomerization of a large GTPase

    Thomas-O Peulen, Carola S Hengstenberg ... Christian Herrmann
    Multimodal spectroscopy (smFRET, EPR, SAXS, and SANS) and integrative structural modeling reveal large-scale domain rearrangements in human guanylate binding protein 1 (hGBP1) that are driving forces for the formation of oligomers that enable its biological function in innate immune defense.

    Decoupling of the onset of anharmonicity between a protein and its surface water around 200 K

    Lirong Zheng, Bingxin Zhou ... Liang Hong
    The dynamical transition between a protein and its surface water is decoupled.
    1. Neuroscience

    Intrinsic timescales as an organizational principle of neural processing across the whole rhesus macaque brain

    Ana MG Manea, Anna Zilverstand ... Jan Zimmermann
    Neuroimaging proves to be a powerful tool for capturing spatial and temporal dynamics across the whole nonhuman primate brain, bridging the gap between human and animal models.
