    Cholinergic modulation of hippocampal calcium activity across the sleep-wake cycle

    Heng Zhou et al.
    Dynamic calcium activity in the hippocampus changes markedly across behavioral and physiological states and depends on muscarinic acetylcholine receptor activation.

    A cholinergic feedback circuit to regulate striatal population uncertainty and optimize reinforcement learning

    Nicholas T Franklin, Michael J Frank
    Computational modeling suggests that feedback between striatal cholinergic neurons and spiny neurons dynamically adjusts learning rates to optimize behavior in a variable world.
    1. Neuroscience

    Synaptic mechanisms underlying modulation of locomotor-related motoneuron output by premotor cholinergic interneurons

    Filipe Nascimento et al.
    The pairing of chemogenetic and electrophysiological approaches reveals mechanisms by which cholinergic synapses modulate the final motor output of the nervous system.
    1. Neuroscience

    Selective attenuation of Ether-a-go-go related K+ currents by endogenous acetylcholine reduces spike-frequency adaptation and network correlation

    Edward D Cui, Ben W Strowbridge
    Acetylcholine, a common modulator in the brain, controls spike-frequency adaptation by specifically attenuating Ether-a-go-go related K+ currents, thereby explaining many cortical network statistical changes often observed in vivo.
    1. Neuroscience

    Sensory perception drives food avoidance through excitatory basal forebrain circuits

    Jay M Patel et al.
    Glutamatergic projection neurons downstream of cholinergic cells in the basal forebrain potently affect feeding behavior by modulating downstream reward and aversion circuits.

    The Natural History of Model Organisms: C. elegans outside the Petri dish

    Lise Frézal, Marie-Anne Félix
    To leverage the tools, resources and knowledge that exist for C. elegans so that we can study ecology, evolution and other aspects of biology, we need to understand the natural history of this important model organism.

    Mechanosensory neurons control the timing of spinal microcircuit selection during locomotion

    Steven Knafo et al.
    Bioluminescence monitoring and selective silencing in zebrafish larva reveal a novel sensorimotor circuit modulating speed in the moving spinal cord.

    SOX2 regulates acinar cell development in the salivary gland

    Elaine Emmerson et al.
    Establishment of the acinar lineage in the salivary gland requires SOX2 and parasympathetic nerves.
    1. Neuroscience

    Formation of retinal direction-selective circuitry initiated by starburst amacrine cell homotypic contact

    Thomas A Ray et al.
    Selective synapse formation in a retinal motion-sensitive circuit is orchestrated by starburst amacrine cells, which use homotypic interactions to initiate formation of a dendritic scaffold that recruits projections from circuit partners.
    1. Neuroscience

    Pauses in cholinergic interneuron firing exert an inhibitory control on striatal output in vivo

    Stefano Zucca et al.
    Optogenetics and in vivo recordings in mice reveal that pauses in cholinergic interneurons offer an alternative mechanism to inhibit subthreshold and suprathreshold events of spiny projection neurons.
