  text: 'Retina is a paradigmatic system for studying sensory encoding: the transformation
    of light into spiking activity of ganglion cells. The inverse problem, where stimulus
    is reconstructed from spikes, has received less attention, especially for complex
    stimuli that should be reconstructed “pixel-by-pixel”. We recorded around a hundred
    neurons from a dense patch in a rat retina and decoded movies of multiple small
    randomly-moving discs. We constructed nonlinear (kernelized and neural network)
    decoders that improved significantly over linear results. An important contribution
    to this was the ability of nonlinear decoders to reliably separate between neural
    responses driven by locally fluctuating light signals, and responses at locally
    constant light driven by spontaneous-like activity. This improvement crucially
    depended on the precise, non-Poisson temporal structure of individual spike trains,
    which originated in the spike-history dependence of neural responses. We propose
    a general principle by which downstream circuitry could discriminate between spontaneous
    and stimulus-driven activity based solely on higher-order statistical structure
    in the incoming spike trains.'

  text: A central goal in theoretical neuroscience is to predict the response properties
    of sensory neurons from first principles. To this end, “efficient coding” posits
    that sensory neurons encode maximal information about their inputs given internal
    constraints. There exist, however, many variants of efficient coding (e.g., redundancy
    reduction, different formulations of predictive coding, robust coding, sparse
    coding, etc.), differing in their regimes of applicability, in the relevance of
    signals to be encoded, and in the choice of constraints. It is unclear how these
    types of efficient coding relate or what is expected when different coding objectives
    are combined. Here we present a unified framework that encompasses previously
    proposed efficient coding models and extends to unique regimes. We show that optimizing
    neural responses to encode predictive information can lead them to either correlate
    or decorrelate their inputs, depending on the stimulus statistics; in contrast,
    at low noise, efficiently encoding the past always predicts decorrelation. Later,
    we investigate coding of naturalistic movies and show that qualitatively different
    types of visual motion tuning and levels of response sparsity are predicted, depending
    on whether the objective is to recover the past or predict the future. Our approach
    promises a way to explain the observed diversity of sensory neural responses,
    as due to multiple functional goals and constraints fulfilled by different cell
    types and/or circuits.

  text: "This package contains data for the publication \"Nonlinear decoding of a
    complex movie from the mammalian retina\" by Deny S. et al, PLOS Comput Biol (2018).
    \r\n\r\nThe data consists of\r\n(i) 91 spike sorted, isolated rat retinal ganglion
    cells that pass stability and quality criteria, recorded on the multi-electrode
    array, in response to the presentation of the complex movie with many randomly
    moving dark discs. The responses are represented as 648000 x 91 binary matrix,
    where the first index indicates the timebin of duration 12.5 ms, and the second
    index the neural identity. The matrix entry is 0/1 if the neuron didn't/did spike
    in the particular time bin.\r\n(ii) README file and a graphical illustration of
    the structure of the experiment, specifying how the 648000 timebins are split
    into epochs where 1, 2, 4, or 10 discs  were displayed, and which stimulus segments
    are exact repeats or unique ball trajectories.\r\n(iii) a 648000 x 400 matrix
    of luminance traces for each of the 20 x 20 positions (\"sites\") in the movie
    frame, with time that is locked to the recorded raster. The luminance traces are
    produced as described in the manuscript by filtering the raw disc movie with a
    small gaussian spatial kernel. "

  text: In the early visual system, cells of the same type perform the same computation
    in different places of the visual field. How these cells code together a complex
    visual scene is unclear. A common assumption is that cells of a single-type extract
    a single-stimulus feature to form a feature map, but this has rarely been observed
    directly. Using large-scale recordings in the rat retina, we show that a homogeneous
    population of fast OFF ganglion cells simultaneously encodes two radically different
    features of a visual scene. Cells close to a moving object code quasilinearly
    for its position, while distant cells remain largely invariant to the object's
    position and, instead, respond nonlinearly to changes in the object's speed. We
    develop a quantitative model that accounts for this effect and identify a disinhibitory
    circuit that mediates it. Ganglion cells of a single type thus do not code for
    one, but two features simultaneously. This richer, flexible neural map might also
    be present in other sensory systems.

  text: 'Advances in multi-unit recordings pave the way for statistical modeling of
    activity patterns in large neural populations. Recent studies have shown that
    the summed activity of all neurons strongly shapes the population response. A
    separate recent finding has been that neural populations also exhibit criticality,
    an anomalously large dynamic range for the probabilities of different population
    activity patterns. Motivated by these two observations, we introduce a class of
    probabilistic models which takes into account the prior knowledge that the neural
    population could be globally coupled and close to critical. These models consist
    of an energy function which parametrizes interactions between small groups of
    neurons, and an arbitrary positive, strictly increasing, and twice differentiable
    function which maps the energy of a population pattern to its probability. We
    show that: 1) augmenting a pairwise Ising model with a nonlinearity yields an
    accurate description of the activity of retinal ganglion cells which outperforms
    previous models based on the summed activity of neurons; 2) prior knowledge that
    the population is critical translates to prior expectations about the shape of
    the nonlinearity; 3) the nonlinearity admits an interpretation in terms of a continuous
    latent variable globally coupling the system whose distribution we can infer from
    data. Our method is independent of the underlying system’s state space; hence,
    it can be applied to other systems such as natural scenes or amino acid sequences
    of proteins which are also known to exhibit criticality.'

  text: Across the nervous system, certain population spiking patterns are observed
    far more frequently than others. A hypothesis about this structure is that these
    collective activity patterns function as population codewords–collective modes–carrying
    information distinct from that of any single cell. We investigate this phenomenon
    in recordings of ∼150 retinal ganglion cells, the retina’s output. We develop
    a novel statistical model that decomposes the population response into modes;
    it predicts the distribution of spiking activity in the ganglion cell population
    with high accuracy. We found that the modes represent localized features of the
    visual stimulus that are distinct from the features represented by single neurons.
    Modes form clusters of activity states that are readily discriminated from one
    another. When we repeated the same visual stimulus, we found that the same mode
    was robustly elicited. These results suggest that retinal ganglion cells’ collective
    signaling is endowed with a form of error-correcting code–a principle that may
    hold in brain areas beyond retina.

  text: Life depends as much on the flow of information as on the flow of energy.
    Here we review the many efforts to make this intuition precise. Starting with
    the building blocks of information theory, we explore examples where it has been
    possible to measure, directly, the flow of information in biological networks,
    or more generally where information-theoretic ideas have been used to guide the
    analysis of experiments. Systems of interest range from single molecules (the
    sequence diversity in families of proteins) to groups of organisms (the distribution
    of velocities in flocks of birds), and all scales in between. Many of these analyses
    are motivated by the idea that biological systems may have evolved to optimize
    the gathering and representation of information, and we review the experimental
    evidence for this optimization, again across a wide range of scales.

  text: Motion tracking is a challenge the visual system has to solve by reading out
    the retinal population. It is still unclear how the information from different
    neurons can be combined together to estimate the position of an object. Here we
    recorded a large population of ganglion cells in a dense patch of salamander and
    guinea pig retinas while displaying a bar moving diffusively. We show that the
    bar’s position can be reconstructed from retinal activity with a precision in
    the hyperacuity regime using a linear decoder acting on 100+ cells. We then took
    advantage of this unprecedented precision to explore the spatial structure of
    the retina’s population code. The classical view would have suggested that the
    firing rates of the cells form a moving hill of activity tracking the bar’s position.
    Instead, we found that most ganglion cells in the salamander fired sparsely and
    idiosyncratically, so that their neural image did not track the bar. Furthermore,
    ganglion cell activity spanned an area much larger than predicted by their receptive
    fields, with cells coding for motion far in their surround. As a result, population
    redundancy was high, and we could find multiple, disjoint subsets of neurons that
    encoded the trajectory with high precision. This organization allows for diverse
    collections of ganglion cells to represent high-accuracy motion information in
    a form easily read out by downstream neural circuits.

  text: 'The activity of a neural network is defined by patterns of spiking and silence
    from the individual neurons. Because spikes are (relatively) sparse, patterns
    of activity with increasing numbers of spikes are less probable, but, with more
    spikes, the number of possible patterns increases. This tradeoff between probability
    and numerosity is mathematically equivalent to the relationship between entropy
    and energy in statistical physics. We construct this relationship for populations
    of up to N = 160 neurons in a small patch of the vertebrate retina, using a combination
    of direct and model-based analyses of experiments on the response of this network
    to naturalistic movies. We see signs of a thermodynamic limit, where the entropy
    per neuron approaches a smooth function of the energy per neuron as N increases.
    The form of this function corresponds to the distribution of activity being poised
    near an unusual kind of critical point. We suggest further tests of criticality,
    and give a brief discussion of its functional significance. '

  text: 'Information processing in the sensory periphery is shaped by natural stimulus
    statistics. In the periphery, a transmission bottleneck constrains performance;
    thus efficient coding implies that natural signal components with a predictably
    wider range should be compressed. In a different regime—when sampling limitations
    constrain performance—efficient coding implies that more resources should be allocated
    to informative features that are more variable. We propose that this regime is
    relevant for sensory cortex when it extracts complex features from limited numbers
    of sensory samples. To test this prediction, we use central visual processing
    as a model: we show that visual sensitivity for local multi-point spatial correlations,
    described by dozens of independently-measured parameters, can be quantitatively
    predicted from the structure of natural images. This suggests that efficient coding
    applies centrally, where it extends to higher-order sensory features and operates
    in a regime in which sensitivity increases with feature variability.'
