    Microsecond sub-domain motions and the folding and misfolding of the mouse prion protein

    Rama Reddy Goluguri et al.
    Native state dynamics of mouse prion protein were measured, and these motions were shown to be having a role in initiation of aggregation.

    The physical dimensions of amyloid aggregates control their infective potential as prion particles

    Ricardo Marchante et al.
    Size threshold and suprastructure formation are key parameters that control the infective potential of amyloid fibrils as prion particles.

    Content-specific activity in frontoparietal and default-mode networks during prior-guided visual perception

    Carlos González-García et al.
    Prior experience alters content-specific neural representations of visual input in frontoparietal and default-mode networks.

    How prior preferences determine decision-making frames and biases in the human brain

    Alizée Lopez-Persem et al.
    Model-based analyses of choice behavior and fMRI activity revealed that prior preferences generate default policies, which frame the decision value signal encoded in the vmPFC, and shift vmPFC pre-choice activity so as to induce a decision bias toward default options.

    Monitoring site-specific conformational changes in real-time reveals a misfolding mechanism of the prion protein

    Ishita Sengupta, Jayant Udgaonkar
    Multi-site FRET measurements of moPrP oligomerization at low pH indicate that major conformational changes take place as monomers reversibly transform into large oligomers, which subsequently disassemble reversibly into small oligomers.

    Structural basis for the prion-like MAVS filaments in antiviral innate immunity

    Hui Xu et al.
    Mitochondrial anti-viral signaling proteins form three-stranded helical filaments in launching innate immune responses against RNA viruses.

    Neural dynamics of visual ambiguity resolution by perceptual prior

    Matthew W Flounders et al.
    Neural dynamics during prior experience-guided visual ambiguity resolution reveal early stimulus-feature processing and late content-specific recognition processing involving large-scale brain networks.

    Development of schemas revealed by prior experience and NMDA receptor knock-out

    George Dragoi, Susumu Tonegawa
    Novel spatial representations by hippocampal cellular assemblies develop on the framework of preconfigured hippocampal networks whose homeostatic synaptic reorganization is accelerated by prior experience and CA3 NMDAR-dependent plasticity.

    Conformation of the nuclear pore in living cells is modulated by transport state

    Joan Pulupa et al.
    Polarized fluorescence microscopy of individual nuclear pores in vivo reveals conformational changes in select domains of proteins of the inner ring.

    Functional limb muscle innervation prior to cholinergic transmitter specification during early metamorphosis in Xenopus

    Francois M Lambert et al.
    Molecular labeling, electrophysiology and calcium imaging have revealed a novel switching of neurotransmitter at the frog neuromuscular junction where motoneurons transiently release glutamate before acetylcholine at synapses on developing hindlimb muscles at the onset of metamorphosis.
