    Single spikes drive sequential propagation and routing of activity in a cortical network

    Juan Luis Riquelme, Mike Hemberger ... Julijana Gjorgjieva
    Single-neuron spikes in a network model of the turtle cortex trigger reliable, yet flexible sequences of activity through a sparse backbone of strong synaptic connections.

    Changing the responses of cortical neurons from sub- to suprathreshold using single spikes in vivo

    Verena Pawlak, David S Greenberg ... Jason ND Kerr
    Changing the order in which presynaptic and postsynaptic cells are repeatedly activated can change what a mammalian visual cortex neuron communicates to downstream neurons.

    Synaptic representation of locomotion in single cerebellar granule cells

    Kate Powell, Alexandre Mathy ... Michael Häusser
    The first patch-clamp recordings from single cerebellar granule cells during locomotion reveal that the entire step sequence can be predicted from both excitatory synaptic input and output spikes from a single neuron.

    The actin-modulating protein synaptopodin mediates long-term survival of dendritic spines

    Kenrick Yap, Alexander Drakew ... Thomas Deller
    Long-term imaging of dentate granule cells reveals that the presence of synaptopodin within large spines, rather than their size, conveys long-term stability to large spines.

    Thalamocortical synapses in the cat visual system in vivo are weak and unreliable

    Madineh Sedigh-Sarvestani, Larry A Palmer, Diego Contreras
    A characterization of LGN-V1 synaptic transmission properties demonstrates thalamocortical synapses in vivo are weak and unreliable, but biologically constrained models show they efficiently drive cortex.

    Modeling apical and basal tree contribution to orientation selectivity in a mouse primary visual cortex layer 2/3 pyramidal cell

    Konstantinos-Evangelos Petousakis, Jiyoung Park ... Panayiota Poirazi
    Apical and basal dendrites contribute differently to single-neuron orientation selectivity, highlighting the impact of feedforward and feedback signal interactions.

    Nanobody repertoire generated against the spike protein of ancestral SARS-CoV-2 remains efficacious against the rapidly evolving virus

    Natalia E Ketaren, Fred D Mast ... John D Aitchison
    High-affinity nanobodies targeting the SARS-CoV-2 spike protein demonstrate sustained effectiveness against current and emerging variants, offering a promising avenue for treatment.
    1. Neuroscience

    Rapid learning in visual cortical networks

    Ye Wang, Valentin Dragoi
    The rapid learning of sensory information in cortical circuits is accompanied by a tight coordination of spike timing with the local theta-band population activity in visual cortex.
    1. Neuroscience

    Nanoconnectomic upper bound on the variability of synaptic plasticity

    Thomas M Bartol Jr, Cailey Bromer ... Terrence J Sejnowski
    Spine heads on the same dendrite receiving input from the same axon are the same size.

    Relationship between simultaneously recorded spiking activity and fluorescence signal in GCaMP6 transgenic mice

    Lawrence Huang, Peter Ledochowitsch ... Lu Li
    Simultaneous calcium imaging and cell-attached recording in GCaMP6 transgenic mice in vivo reveals spiking-fluorescence relationship that supports more refined inference of neuronal activities from calcium imaging data.
