    Earliest infections predict the age distribution of seasonal influenza A cases

    Philip Arevalo, Huong Q McLean ... Sarah Cobey
    First influenza infections determine susceptibility to future seasonal influenza infection throughout life, and may impact vaccine effectiveness.

    Modeling the dynamics of Plasmodium falciparum gametocytes in humans during malaria infection

    Pengxing Cao, Katharine A Collins ... James M McCaw
    A mathematical model of blood-stage infection with Plasmodium falciparum malaria capturing the sexual stage of the parasite life-cycle is validated against human data, providing new insight into human-to-mosquito transmission.

    Trading mental effort for confidence in the metacognitive control of value-based decision-making

    Douglas G Lee, Jean Daunizeau
    Intra-individual variability in choice, response time, subjective effort, confidence, and choice-induced preference change and certainty gain is explained by a cost–benefit model of cognitive resource allocation.

    Flexible control of representational dynamics in a disinhibition-based model of decision-making

    Bo Shen, Kenway Louie, Paul Glimcher
    Local disinhibition provides a biologically plausible mechanism for flexible top-down control of network states that integrates normalized value coding, winner-take-all choice, and persistent activity in a single circuit of decision-making.

    A flexible framework for simulating and fitting generalized drift-diffusion models

    Maxwell Shinn, Norman H Lam, John D Murray
    Sophisticated decision-making mechanisms and complex experimental paradigms can be modeled, simulated, and fit to empirical response time data, using a flexible and efficient computational modeling framework.

    TMS-evoked responses are driven by recurrent large-scale network dynamics

    Davide Momi, Zheng Wang, John D Griffiths
    Whole-brain computational modelling, incorporating novel ML-based parameter estimation techniques, reveals how transcranial magnetic stimulation-evoked brain responses are driven at earlier timepoints by local echoes of the external stimulus, and at later timepoints by large-scale network reverberation across the connectome.

    Differential impact of self and environmental antigens on the ontogeny and maintenance of CD4+ T cell memory

    Thea Hogan, Maria Nowicka ... Benedict Seddon
    Comparing mice in clean and dirty environments reveals that environment drives initial establishment and size of T cell memory compartments, but not their maintenance in adults.

    A small, computationally flexible network produces the phenotypic diversity of song recognition in crickets

    Jan Clemens, Stefan Schöneich ... Berthold Hedwig
    A computational model of the neuronal network that recognizes mating signals reveals network properties that support and constrain behavioral diversity in a species group.

    Rigid firing sequences undermine spatial memory codes in a neurodegenerative mouse model

    Jingheng Cheng, Daoyun Ji
    In a mouse model of neurodegeneration, hippocampal firing sequences that normally encode spatial memories become disengaged from external space.

    Reinforcement regulates timing variability in thalamus

    Jing Wang, Eghbal Hosseini ... Mehrdad Jazayeri
    When behavioral outcomes are unfavorable, the brain searches for better outcomes by deliberately increasing its internal variability.
