    Decoding the brain state-dependent relationship between pupil dynamics and resting state fMRI signal fluctuation

    Filip Sobczak, Patricia Pais-Roldán ... Xin Yu
    The variability of the pupil–fMRI relationship was characterized through a combination of clustering and prediction methods, which revealed brain state-specific subcortical and neuromodulatory activation patterns reflected in pupil dynamics.
