    Ephrin-B3 controls excitatory synapse density through cell-cell competition for EphBs

    Nathan T Henderson et al.
    Competition between neurons for postsynaptic ephrin-B3 controls distribution of a limited pool of synapses and defines a novel trans-synaptic mechanism enabling neurons to set the number of synapses they receive.

    Cerebellar involvement in an evidence-accumulation decision-making task

    Ben Deverett et al.
    In a new evidence-accumulation decision-making task, activity of the lateral posterior cerebellum is necessary for accurate performance, and somatic and dendritic activity in Purkinje cells contains choice/evidence and error-related information.

    Computational models of O-LM cells are recruited by low or high theta frequency inputs depending on h-channel distributions

    Vladislav Sekulić, Frances K Skinner
    The contribution of biophysical ion channels to neuron function can be predicted by taking advantage of an ongoing dialogue between model and experiment.

    Thalamus and claustrum control parallel layer 1 circuits in retrosplenial cortex

    Ellen KW Brennan et al.
    Parallel input streams to layer 1 identify a computationally distinct principal neuronal subtype ideally positioned to support spatial orientation computations in the granular retrosplenial cortex.

    Competition for synaptic building blocks shapes synaptic plasticity

    Jochen Triesch et al.
    Computational model reveals how the fast exchange of neurotransmitter receptors between synapses induces a competition leading to a transient form of heterosynaptic plasticity and shaping the induction of homosynaptic plasticity.

    The comprehensive connectome of a neural substrate for ‘ON’ motion detection in Drosophila

    Shin-ya Takemura et al.
    Connectomic analysis identifies the complex circuits of a visual motion-sensing neuron that qualify them to generate direction-selective motion sensing signals using both Hassenstein-Reichardt and Barlow-Levick models.

    Wiring variations that enable and constrain neural computation in a sensory microcircuit

    William F Tobin et al.
    Systematic and coordinated variations in morphology and connectivity can structurally tune a microcircuit's computation but non-systematic variably also exists, imparting "connection noise" that potentially limits processing performance.

    General features of the retinal connectome determine the computation of motion anticipation

    Jamie Johnston, Leon Lagnado
    Feedforward inhibition generates motion anticipation by selectively decreasing sensitivity to a stimulus as it moves across the latter part of a retinal ganglion cell's receptive field.

    Waves of actin and microtubule polymerization drive microtubule-based transport and neurite growth before single axon formation

    Amy M Winans et al.
    Waves of polymerizing actin work in concert with microtubule polymerization to lay down more microtubules tracks and transiently increase microtubule-based transport into the growing neurite.

    Dendritic sodium spikes are required for long-term potentiation at distal synapses on hippocampal pyramidal neurons

    Yujin Kim et al.
    At distal synapses onto hippocampal CA1 pyramidal neurons, synaptic plasticity is dependent on dendritically initiated sodium spikes, thus establishing a new role for voltage-gated sodium channels in the dendrites that may have important implications for how learning rules are implemented.
