    A novel region in the CaV2.1 α1 subunit C-terminus regulates fast synaptic vesicle fusion and vesicle docking at the mammalian presynaptic active zone

    Matthias Lübbert, R Oliver Goral ... Samuel M Young Jr
    A novel region in the CaV2.1 α1 subunit regulates coupling of synaptic vesicles to CaV2.1 calcium channels, synaptic vesicle release and docking, and the size of the fast and total releasable pools of synaptic vesicles.

    Sequential neuromodulation of Hebbian plasticity offers mechanism for effective reward-based navigation

    Zuzanna Brzosko, Sara Zannone ... Ole Paulsen
    Sequential neuromodulation by acetylcholine and dopamine enables correlational synaptic learning which, when incorporated into a computational model, yields effective navigation toward changing reward locations as in natural foraging behavior.

    Selective and regulated trapping of nicotinic receptor weak base ligands and relevance to smoking cessation

    Anitha P Govind, Yolanda F Vallejo ... William N Green
    The smoking cessation drug varenicline (Chantix) and other weak base ligands reduce a4b2-type nicotinic receptor (a4b2R) upregulation through slow intracellular release due to selective trapping in acidic vesicles that contain a4b2Rs.

    A spiral attractor network drives rhythmic locomotion

    Angela M Bruno, William N Frost, Mark D Humphries
    The neural population of the Aplysia's pedal ganglion are a low-dimensional spiral attractor, and the parameters of the attractor directly define the properties of the Aplysia's escape locomotion behaviour.

    Task-dependent recurrent dynamics in visual cortex

    Satohiro Tajima, Kowa Koida ... Hidehiko Komatsu
    A decoding-based, state-space reconstruction reveals that neurons in macaque IT cortex change the structure of their collective attractor dynamics depending on task contexts.

    Physiological and pathophysiological control of synaptic GluN2B-NMDA receptors by the C-terminal domain of amyloid precursor protein

    Paula A Pousinha, Xavier Mouska ... Hélène Marie
    The APP intracellular domain (AICD) physiologically regulates synaptic GluN2B-containing NMDA receptor current, a process that could contribute to pathological Alzheimer's disease-related synaptic failure upon increase of AICD levels in adult neurons.
    1. Neuroscience

    Pro-death NMDA receptor signaling is promoted by the GluN2B C-terminus independently of Dapk1

    Jamie McQueen, Tomás J Ryan ... Giles E Hardingham
    Excitotoxicity driven by NMDA receptor hyper-activation does not involve DAPK1-dependent events in vitro or in vivo, and previously described DAPK1-NMDAR disrupting peptides act by blocking the NMDA receptor.

    Pharmacological evidence for a metabotropic glutamate receptor heterodimer in neuronal cells

    David Moreno Delgado, Thor C Møller ... Jean-Philippe Pin
    Innovative approaches were used to identify the specific pharmacological properties of heterodimeric metabotropic glutamate receptors composed of mGlu2 and mGlu4 subunits, and reveal their existence in a neuronal cell line and in perforant path terminals.

    Plasticity of calcium-permeable AMPA glutamate receptors in Pro-opiomelanocortin neurons

    Shigetomo Suyama, Alexandra Ralevski ... Tamas L Horvath
    Neurons in the hypothalamus that promote satiety manifest plasticity of their response to the excitatory transmitter, glutamate, by re-organizing the composition of a specific glutamare receptor.

    Energy imbalance alters Ca2+ handling and excitability of POMC neurons

    Lars Paeger, Andreas Pippow ... Peter Kloppenburg
    The development of diet-dependent obesity results in the deterioration of calcium homeostasis in pro-opiomelanocortin-expressing neurons and impaired function of the same neurons.
