    Biophysical models reveal the relative importance of transporter proteins and impermeant anions in chloride homeostasis

    Kira M Düsterwald, Christopher B Currin ... Joseph V Raimondo
    Mathematical models with experimental validation show that chloride transporters in the cell membrane, and not negatively charged impermeant molecules, generate the driving force used by GABA receptors to silence neurons.

    A simple biophysical model emulates budding yeast chromosome condensation

    Tammy MK Cheng, Sebastian Heeger ... Frank Uhlmann
    A computational model of a yeast chromosome, based on first principles, recapitulates in vivo chromosome behavior, and thus provides unprecedented insight into what the inside of a chromosome is likely to look like.

    Basolateral amygdala oscillations enable fear learning in a biophysical model

    Anna Cattani, Don B Arnold ... Nancy Kopell
    Computational modeling suggests that the BLA is capable of producing the recorded LFP rhythms via interactions of interneuron subtypes, and that those rhythms may be necessary for associative learning.

    Inhibitory control of frontal metastability sets the temporal signature of cognition

    Vincent Fontanier, Matthieu Sarazin ... Emmanuel Procyk
    Single unit recordings in monkeys and biophysical modelling demonstrate that local inhibitory-controlled metastable neural states specify the temporal organization of cognitive functions in frontal areas.

    Cell-scale biophysical determinants of cell competition in epithelia

    Daniel Gradeci, Anna Bove ... Guillaume Charras
    Mechanical competition is controlled by biophysical parameters that regulate cellular homeostatic density, while biochemical competition is regulated by parameters that influence the organisation of cells in a tissue.

    Diverse and complex muscle spindle afferent firing properties emerge from multiscale muscle mechanics

    Kyle P Blum, Kenneth S Campbell ... Lena H Ting
    Diverse muscle spindle firing, critical for a range of sensorimotor behaviors, is compactly explained by first principles of force development in specialized muscle fibers within the sensors.

    Inferring synaptic inputs from spikes with a conductance-based neural encoding model

    Kenneth W Latimer, Fred Rieke, Jonathan W Pillow
    The conductance-based encoding model creates a new bridge between statistical models and biophysical models of neurons, and infers visually-evoked excitatory and inhibitory synaptic conductances from spike trains in macaque retina.
