    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.

    The laminar organization of the Drosophila ellipsoid body is semaphorin-dependent and prevents the formation of ectopic synaptic connections

    Xiaojun Xie et al.
    The organization of layered/laminated axon projections in specific regions of the fruitfly central brain is regulated by short-range repulsive guidance and is critical for local inhibitory circuit formation and function.

    A cellular and regulatory map of the cholinergic nervous system of C. elegans

    Laura Pereira et al.
    Analyzing a map of all cholinergic neurons in the nematode C. elegans shows how these neurons are embedded in the C. elegans connectome and reveals the regulatory factors controlling their development.

    Pharmacological dimerization and activation of the exchange factor eIF2B antagonizes the integrated stress response

    Carmela Sidrauski et al.
    A drug-like molecule called ISRIB, which activates the translation initiation factor eIF2B, antagonizes stress responses as diverse as protein misfolding and nutrient deprivation, and restores protein synthesis, enhancing memory.

    Biophysical mechanisms in the mammalian respiratory oscillator re-examined with a new data-driven computational model

    Ryan S Phillips et al.
    Computational modeling motivated by recent experiments clarifies biophysical mechanisms generating the rhythm and amplitude of breathing at the level of neurons and brain circuits in mammals.

    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.

    eIF2α-mediated translational control regulates the persistence of cocaine-induced LTP in midbrain dopamine neurons

    Andon N Placzek et al.
    Building on previous work (Huang et al., 2016), we show that translational control by p-eIF2α is a defense mechanism that prevents persistent cocaine-induced synaptic synaptic potentiation underlying compulsive drug seeking.

    Recruitment of inhibition and excitation across mouse visual cortex depends on the hierarchy of interconnecting areas

    Rinaldo David D'Souza et al.
    The relative recruitment of excitatory and inhibitory neurons by cortico-cortical interareal pathways depends on the hierarchy of areas and the laminar location of the neurons.

    NPTX2 and cognitive dysfunction in Alzheimer’s Disease

    Mei-Fang Xiao et al.
    Dysfunction of pyramidal neuron-PV interneuron circuits contributes to cognitive failure in Alzheimer's disease.

    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.
