  1. What is the dynamical regime of cerebral cortex?

    Publication
    Many studies have shown that the excitation and inhibition received by cortical neurons remain roughly balanced across many conditions. A key question for understanding the dynamical regime of …

  2. What is the dynamical regime of cerebral cortex?

    Many studies have shown that the excitation and inhibition received by cortical neurons remain roughly balanced across many conditions. A key question for understanding the dynamical regime of …

  3. Interrogating theoretical models of neural computation with emergent property inference

    Publication
    A cornerstone of theoretical neuroscience is the circuit model: a system of equations that captures a hypothesized neural mechanism. Such models are valuable when they give rise to …

  4. A Disinhibitory Circuit for Contextual Modulation in Primary Visual Cortex

    Publication
    Context guides perception by influencing stimulus saliency. Accordingly, in visual cortex, responses to a stimulus are modulated by context, the visual scene surrounding the stimulus. Responses are suppressed …

  5. How biological attention mechanisms improve task performance in a large-scale visual system model.

    Publication
    How does attentional modulation of neural activity enhance performance? Here we use a deep convolutional neural network as a large-scale model of the visual system to address …

  6. The Dynamical Regime of Sensory Cortex: Stable Dynamics around a Single Stimulus-Tuned Attractor Account for Patterns of Noise Variability.

    Publication
    Correlated variability in cortical activity is ubiquitously quenched following stimulus onset, in a stimulus-dependent manner. These modulations have been attributed to circuit dynamics involving either multiple stable …

  7. A unifying motif for spatial and directional surround suppression.

    Publication
    … or brain region, we wondered whether similar modulatory influences might be observed for other stimulus dimensions and other regions. We tested for specific patterns of modulatory influences …
