    Presynaptic NMDA receptors facilitate short-term plasticity and BDNF release at hippocampal mossy fiber synapses

    Pablo J Lituma, Hyung-Bae Kwon ... Pablo E Castillo
    By facilitating glutamate and BDNF release, presynaptic NMDA receptors may control information transfer from the dentate gyrus to the CA3 area of the hippocampus.

    Analogue signaling of somatodendritic synaptic activity to axon enhances GABA release in young cerebellar molecular layer interneurons

    Federico Trigo, Shin-ya Kawaguchi
    In cerebellar interneurons, somatodendritic subthreshold synaptic activity travels down the axon and augments AP-dependent GABA release by a modulation of the intermediate states of voltage-dependent Ca++ channels in the presynaptic boutons.

    Neurotransmission: The secret life of memory receptors

    Hovy Ho-Wai Wong, Olivier Camiré, P Jesper Sjöström
    The canonical hippocampal NMDA memory receptor also controls the release of the transmitter glutamate and the growth factor BDNF.

    Dopaminergic challenge dissociates learning from primary versus secondary sources of information

    Alicia J Rybicki, Sophie L Sowden ... Jennifer L Cook
    Haloperidol comparably affects learning from social and non-social sources when they are the primary source of information but does not affect learning from (social or non-social) secondary sources, providing evidence in support of domain-general neurochemical mechanisms underpinning social learning.

    Release-dependent feedback inhibition by a presynaptically localized ligand-gated anion channel

    Seika Takayanagi-Kiya, Keming Zhou, Yishi Jin
    An anion-selective ligand gated channel acts as a presynaptic auto-receptor to modulate vesicle release and neuronal excitation.

    Initial elevations in glutamate and dopamine neurotransmission decline with age, as does exploratory behavior, in LRRK2 G2019S knock-in mice

    Mattia Volta, Dayne A Beccano-Kelly ... Austen J Milnerwood
    LRRK2 G2019S knock-in mice are a genetically faithful model that recapitulates the slow disease progression of familial PD, with initial alterations to behaviour and neurotransmission providing early pathophysiological targets for neuroprotective interventions.

    Presynaptic GABAB receptors functionally uncouple somatostatin interneurons from the active hippocampal network

    Sam A Booker, Harumi Harada ... Imre Vida
    Presynaptic GABAB receptors are highly expressed and strongly suppress synaptic transmission at the input and output of hippocampal somatostatin interneurons.
    1. Neuroscience

    Dopamine differentially modulates the size of projection neuron ensembles in the intact and dopamine-depleted striatum

    Marta Maltese, Jeffrey R March ... Nicolas X Tritsch
    In addition to modulating firing rates, the neurotransmitter dopamine exerts a strong influence on the overall number of neurons in striatum that are recruited during behavior.
    1. Neuroscience

    RIM is essential for stimulated but not spontaneous somatodendritic dopamine release in the midbrain

    Brooks G Robinson, Xintong Cai ... Pascal S Kaeser
    Midbrain dopamine neurons use sophisticated secretory machinery to establish specialized sites for action potential-evoked release of dopamine from their cell bodies and dendrites.
