    The step-wise pathway of septin hetero-octamer assembly in budding yeast

    Andrew Weems, Michael McMurray
    In budding yeast cells, slow monomeric septin GTPase activity and the cytosolic GTP:GDP ratio dictate the relative incorporation of alternative subunits during septin hetero-oligomer assembly, which proceeds by discrete, ordered steps dependent on allostery between interaction interfaces.

    Ring-like oligomers of Synaptotagmins and related C2 domain proteins

    Maria N Zanetti et al.
    A model for synchronous neurotransmitter release suggests that when not in the presence of calcium ions, Synaptotagmin proteins form ring-like structures between the vesicle and plasma membrane that prevent spontaneous fusion.

    Attenuation of dopamine-modulated prefrontal value signals underlies probabilistic reward learning deficits in old age

    Lieke de Boer et al.
    Attenuated anticipatory activity in ventromedial prefrontal cortex is modulated by dopamine D1 receptor density in nucleus accumbens, and accounts for impaired probabilistic reward learning in older adults.

    The Na+/Ca2+, K+ exchanger NCKX4 is required for efficient cone-mediated vision

    Frans Vinberg et al.
    Molecular, genetic, and functional analysis is used to show that the olfactory Na+/Ca2+, K+ exchanger NCKX4 is expressed in cone photoreceptors and is critical for the wide operating range and high temporal resolution of cone-mediated vision.

    Embryonic transcription factor expression in mice predicts medial amygdala neuronal identity and sex-specific responses to innate behavioral cues

    Julieta E Lischinsky et al.
    Studying the development of the medial amygdala in the mouse reveals how the brain may potentially process sex differences in innate behaviors such as mating.

    A subset of ipRGCs regulates both maturation of the circadian clock and segregation of retinogeniculate projections in mice

    Kylie S Chew et al.
    A single subpopulation of photoreceptors constitutes a shared node in the neural networks that regulate light-dependent maturation of the circadian clock and light-independent refinement of retinal ganglion cell projections to the brain.

    Inhibitory control of correlated intrinsic variability in cortical networks

    Carsen Stringer et al.
    A new cortical network model fit directly to multi-neuron recordings reveals that local inhibitory feedback can control neural dynamics, modulate brain state and enhance sensory processing.

    Physical limits to magnetogenetics

    Markus Meister
    Recent reports on the ability of biological molecules to sense magnetic fields are found to be inconsistent with basic physical principles.

    Transformation of spatiotemporal dynamics in the macaque vestibular system from otolith afferents to cortex

    Jean Laurens et al.
    The spatial and dynamic properties of self-motion signals are acquired at the first stage of otolith signal transformation, which is in the brainstem and cerebellum, and conserved across brainstem, cerebellar and cortical areas.

    AMPK acts as a molecular trigger to coordinate glutamatergic signals and adaptive behaviours during acute starvation

    Moloud Ahmadi, Richard Roy
    AMP-activated protein kinase directly coordinates glutamatergic signalling during starvation in C. elegans.
