  text: 'To interpret the sensory environment, the brain combines ambiguous sensory
    measurements with knowledge that reflects context-specific prior experience. But
    environmental contexts can change abruptly and unpredictably, resulting in uncertainty
    about the current context. Here we address two questions: how should context-specific
    prior knowledge optimally guide the interpretation of sensory stimuli in changing
    environments, and do human decision-making strategies resemble this optimum? We
    probe these questions with a task in which subjects report the orientation of
    ambiguous visual stimuli that were drawn from three dynamically switching distributions,
    representing different environmental contexts. We derive predictions for an ideal
    Bayesian observer that leverages knowledge about the statistical structure of
    the task to maximize decision accuracy, including knowledge about the dynamics
    of the environment. We show that its decisions are biased by the dynamically changing
    task context. The magnitude of this decision bias depends on the observer’s continually
    evolving belief about the current context. The model therefore not only predicts
    that decision bias will grow as the context is indicated more reliably, but also
    as the stability of the environment increases, and as the number of trials since
    the last context switch grows. Analysis of human choice data validates all three
    predictions, suggesting that the brain leverages knowledge of the statistical
    structure of environmental change when interpreting ambiguous sensory signals.'

  text: Despite the considerable progress of in vivo neural recording techniques,
    inferring the biophysical mechanisms underlying large scale coordination of brain
    activity from neural data remains challenging. One obstacle is the difficulty
    to link high dimensional functional connectivity measures to mechanistic models
    of network activity. We address this issue by investigating spike-field coupling
    (SFC) measurements, which quantify the synchronization between, on the one hand,
    the action potentials produced by neurons, and on the other hand mesoscopic “field”
    signals, reflecting subthreshold activities at possibly multiple recording sites.
    As the number of recording sites gets large, the amount of pairwise SFC measurements
    becomes overwhelmingly challenging to interpret. We develop Generalized Phase
    Locking Analysis (GPLA) as an interpretable dimensionality reduction of this multivariate
    SFC. GPLA describes the dominant coupling between field activity and neural ensembles
    across space and frequencies. We show that GPLA features are biophysically interpretable
    when used in conjunction with appropriate network models, such that we can identify
    the influence of underlying circuit properties on these features. We demonstrate
    the statistical benefits and interpretability of this approach in various computational
    models and Utah array recordings. The results suggest that GPLA, used jointly
    with biophysical modeling, can help uncover the contribution of recurrent microcircuits
    to the spatio-temporal dynamics observed in multi-channel experimental recordings.

  text: Understanding and characterising biochemical processes inside single cells
    requires experimental platforms that allow one to perturb and observe the dynamics
    of such processes as well as computational methods to build and parameterise models
    from the collected data. Recent progress with experimental platforms and optogenetics
    has made it possible to expose each cell in an experiment to an individualised
    input and automatically record cellular responses over days with fine time resolution.
    However, methods to infer parameters of stochastic kinetic models from single-cell
    longitudinal data have generally been developed under the assumption that experimental
    data is sparse and that responses of cells to at most a few different input perturbations
    can be observed. Here, we investigate and compare different approaches for calculating
    parameter likelihoods of single-cell longitudinal data based on approximations
    of the chemical master equation (CME) with a particular focus on coupling the
    linear noise approximation (LNA) or moment closure methods to a Kalman filter.
    We show that, as long as cells are measured sufficiently frequently, coupling
    the LNA to a Kalman filter allows one to accurately approximate likelihoods and
    to infer model parameters from data even in cases where the LNA provides poor
    approximations of the CME. Furthermore, the computational cost of filtering-based
    iterative likelihood evaluation scales advantageously in the number of measurement
    times and different input perturbations and is thus ideally suited for data obtained
    from modern experimental platforms. To demonstrate the practical usefulness of
    these results, we perform an experiment in which single cells, equipped with an
    optogenetic gene expression system, are exposed to various different light-input
    sequences and measured at several hundred time points and use parameter inference
    based on iterative likelihood evaluation to parameterise a stochastic model of
    the system.

  text: Neuronal networks encode information through patterns of activity that define
    the networks’ function. The neurons’ activity relies on specific connectivity
    structures, yet the link between structure and function is not fully understood.
    Here, we tackle this structure-function problem with a new conceptual approach.
    Instead of manipulating the connectivity directly, we focus on upper triangular
    matrices, which represent the network dynamics in a given orthonormal basis obtained
    by the Schur decomposition. This abstraction allows us to independently manipulate
    the eigenspectrum and feedforward structures of a connectivity matrix. Using this
    method, we describe a diverse repertoire of non-normal transient amplification,
    and to complement the analysis of the dynamical regimes, we quantify the geometry
    of output trajectories through the effective rank of both the eigenvector and
    the dynamics matrices. Counter-intuitively, we find that shrinking the eigenspectrum’s
    imaginary distribution leads to highly amplifying regimes in linear and long-lasting
    dynamics in nonlinear networks. We also find a trade-off between amplification
    and dimensionality of neuronal dynamics, i.e., trajectories in neuronal state-space.
    Networks that can amplify a large number of orthogonal initial conditions produce
    neuronal trajectories that lie in the same subspace of the neuronal state-space.
    Finally, we examine networks of excitatory and inhibitory neurons. We find that
    the strength of global inhibition is directly linked with the amplitude of amplification,
    such that weakening inhibitory weights also decreases amplification, and that
    the eigenspectrum’s imaginary distribution grows with an increase in the ratio
    between excitatory-to-inhibitory and excitatory-to-excitatory connectivity strengths.
    Consequently, the strength of global inhibition reveals itself as a strong signature
    for amplification and a potential control mechanism to switch dynamical regimes.
    Our results shed a light on how biological networks, i.e., networks constrained
    by Dale’s law, may be optimised for specific dynamical regimes.

  text: 'In repeated interactions, players can use strategies that respond to the
    outcome of previous rounds. Much of the existing literature on direct reciprocity
    assumes that all competing individuals use the same strategy space. Here, we study
    both learning and evolutionary dynamics of players that differ in the strategy
    space they explore. We focus on the infinitely repeated donation game and compare
    three natural strategy spaces: memory-1 strategies, which consider the last moves
    of both players, reactive strategies, which respond to the last move of the co-player,
    and unconditional strategies. These three strategy spaces differ in the memory
    capacity that is needed. We compute the long term average payoff that is achieved
    in a pairwise learning process. We find that smaller strategy spaces can dominate
    larger ones. For weak selection, unconditional players dominate both reactive
    and memory-1 players. For intermediate selection, reactive players dominate memory-1
    players. Only for strong selection and low cost-to-benefit ratio, memory-1 players
    dominate the others. We observe that the supergame between strategy spaces can
    be a social dilemma: maximum payoff is achieved if both players explore a larger
    strategy space, but smaller strategy spaces dominate.'

  text: Realistic models of biological processes typically involve interacting components
    on multiple scales, driven by changing environment and inherent stochasticity.
    Such models are often analytically and numerically intractable. We revisit a dynamic
    maximum entropy method that combines a static maximum entropy with a quasi-stationary
    approximation. This allows us to reduce stochastic non-equilibrium dynamics expressed
    by the Fokker-Planck equation to a simpler low-dimensional deterministic dynamics,
    without the need to track microscopic details. Although the method has been previously
    applied to a few (rather complicated) applications in population genetics, our
    main goal here is to explain and to better understand how the method works. We
    demonstrate the usefulness of the method for two widely studied stochastic problems,
    highlighting its accuracy in capturing important macroscopic quantities even in
    rapidly changing non-stationary conditions. For the Ornstein-Uhlenbeck process,
    the method recovers the exact dynamics whilst for a stochastic island model with
    migration from other habitats, the approximation retains high macroscopic accuracy
    under a wide range of scenarios in a dynamic environment.

  text: Resources are rarely distributed uniformly within a population. Heterogeneity
    in the concentration of a drug, the quality of breeding sites, or wealth can all
    affect evolutionary dynamics. In this study, we represent a collection of properties
    affecting the fitness at a given location using a color. A green node is rich
    in resources while a red node is poorer. More colors can represent a broader spectrum
    of resource qualities. For a population evolving according to the birth-death
    Moran model, the first question we address is which structures, identified by
    graph connectivity and graph coloring, are evolutionarily equivalent. We prove
    that all properly two-colored, undirected, regular graphs are evolutionarily equivalent
    (where “properly colored” means that no two neighbors have the same color). We
    then compare the effects of background heterogeneity on properly two-colored graphs
    to those with alternative schemes in which the colors are permuted. Finally, we
    discuss dynamic coloring as a model for spatiotemporal resource fluctuations,
    and we illustrate that random dynamic colorings often diminish the effects of
    background heterogeneity relative to a proper two-coloring.

  text: Mathematical models have been used successfully at diverse scales of biological
    organization, ranging from ecology and population dynamics to stochastic reaction
    events occurring between individual molecules in single cells. Generally, many
    biological processes unfold across multiple scales, with mutations being the best
    studied example of how stochasticity at the molecular scale can influence outcomes
    at the population scale. In many other contexts, however, an analogous link between
    micro- and macro-scale remains elusive, primarily due to the challenges involved
    in setting up and analyzing multi-scale models. Here, we employ such a model to
    investigate how stochasticity propagates from individual biochemical reaction
    events in the bacterial innate immune system to the ecology of bacteria and bacterial
    viruses. We show analytically how the dynamics of bacterial populations are shaped
    by the activities of immunity-conferring enzymes in single cells and how the ecological
    consequences imply optimal bacterial defense strategies against viruses. Our results
    suggest that bacterial populations in the presence of viruses can either optimize
    their initial growth rate or their population size, with the first strategy favoring
    simple immunity featuring a single restriction modification system and the second
    strategy favoring complex bacterial innate immunity featuring several simultaneously
    active restriction modification systems.
