    The interpretation of computational model parameters depends on the context

    Maria Katharina Eckstein, Sarah L Master ... Anne GE Collins
    Context factors such as experimental task and model parameterization can significantly impact modeling results, such that across tasks, the same participants show different fitted parameter values, and parameters capture different cognitive processes across tasks.

    Interacting rhythms enhance sensitivity of target detection in a fronto-parietal computational model of visual attention

    Amélie Aussel, Ian C Fiebelkorn ... Benjamin Rafael Pittman-Polletta
    A biophysical cortical circuit model reveals how thalamic inputs mediate complex dynamics in the frontal eye fields and lateral intraparietal area, enabling rhythmic enhancements in visual sensitivity observed behaviorally.

    Approach-avoidance reinforcement learning as a translational and computational model of anxiety-related avoidance

    Yumeya Yamamori, Oliver J Robinson, Jonathan P Roiser
    A computational and translational approach to measuring anxiety-related behaviour was validated in two large independent samples, presenting opportunities for cross-species anxiety research and potential implications for anxiolytic drug development.

    Computational modeling identifies embolic stroke of undetermined source patients with potential arrhythmic substrate

    Savannah F Bifulco, Griffin D Scott ... Patrick M Boyle
    In models reconstructed from MRI scans of patients with embolic stroke of undetermined source, computational simulations reveal that fibrosis has the intrinsic capacity to sustain arrhythmia drivers when subjected to triggered activity known to exist in patients with atrial fibrillation.

    Computational models of O-LM cells are recruited by low or high theta frequency inputs depending on h-channel distributions

    Vladislav Sekulić, Frances K Skinner
    The contribution of biophysical ion channels to neuron function can be predicted by taking advantage of an ongoing dialogue between model and experiment.

    Personalized computational heart models with T1-mapped fibrotic remodeling predict sudden death risk in patients with hypertrophic cardiomyopathy

    Ryan P O'Hara, Edem Binka ... Natalia A Trayanova
    Personalized virtual-heart technology for arrhythmia risk assessment could transform the management of hypertrophic cardiomyopathy patients, eliminating many unnecessary primary-prevention defibrillator deployments while ensuring patients at high risk for arrhythmia are adequately protected.

    An oscillating computational model can track pseudo-rhythmic speech by using linguistic predictions

    Sanne ten Oever, Andrea E Martin
    An oscillating computational model combined with a predictive internal linguistic model can track naturally timed speech in which pseudo-rhythmicity is related to the predictability of words within their sentence context.

    Feedback inhibition and its control in an insect olfactory circuit

    Subhasis Ray, Zane N Aldworth, Mark A Stopfer
    Electrophysiological recordings and a large-scale biophysical model show that a unique inhibitory neuron plays a central role in structuring olfactory codes in the insect brain.

    Mechanisms of distributed working memory in a large-scale network of macaque neocortex

    Jorge F Mejías, Xiao-Jing Wang
    An anatomically constrained computational model of the macaque cortical network demonstrates the emergence of large-scale distributed patterns of mnemonic activity sustained by long-range cortico-cortical interactions.
