    CB1-receptor-mediated inhibitory LTD triggers presynaptic remodeling via protein synthesis and ubiquitination

    Hannah R Monday, Mathieu Bourdenx ... Pablo E Castillo
    CB1-receptor-mediated inhibitory long-term depression (LTD) relies on both protein synthesis and ubiquitination to elicit structural changes that underlie long-term reduction of GABA release.

    Glutamate is required for depression but not potentiation of long-term presynaptic function

    Zahid Padamsey, Rudi Tong, Nigel Emptage
    Electrophysiological and optical analysis of neurotransmitter release at central synapses reveals that glutamate signalling is not required for the long-term potentiation (LTP) of presynaptic function, and instead only promotes presynaptic long-term depression (LTD).

    Translational control by eIF2α phosphorylation regulates vulnerability to the synaptic and behavioral effects of cocaine

    Wei Huang, Andon N Placzek ... Mauro Costa-Mattioli
    Vulnerability to cocaine addiction during adolescence depends on translational control.

    The fate of hippocampal synapses depends on the sequence of plasticity-inducing events

    J Simon Wiegert, Mauro Pulin ... Thomas G Oertner
    Non-invasive optogenetic induction of synaptic plasticity revealed that long-term potentiation and long-term depression alter the chances of a synapse to survive the next seven days.

    Occurrence of long-term depression in the cerebellar flocculus during adaptation of optokinetic response

    Takuma Inoshita, Tomoo Hirano
    Motor training decreased the unit synaptic response and suppressed induction of long-term depression at parallel fiber to Purkinje cell synapses in the cerebellum, supporting involvement of long-term depression in motor learning.

    Synaptic activity regulates AMPA receptor trafficking through different recycling pathways

    Ning Zheng, Okunola Jeyifous ... William N Green
    There are at least two separate pathways for AMPA receptor recycling, which are regulated by synaptic activity.

    LTD at amygdalocortical synapses as a novel mechanism for hedonic learning

    Melissa S Haley, Stephen Bruno ... Arianna Maffei
    Taking advantage of awell-established learning paradigm, conditioned taste aversion (CTA), change of hedonic value of a palatable tastant revealed the neural mechanisms encoding this learning process.

    Endocannabinoid dynamics gate spike-timing dependent depression and potentiation

    Yihui Cui, Ilya Prokin ... Hugues Berry
    The molecular mechanisms beyond the bidirectionality (tTLP and tLTD) of endocanabinoid spike-timing dependent synaptic plasticity have been identified.

    DYT1 dystonia increases risk taking in humans

    David Arkadir, Angela Radulescu ... Yael Niv
    Patients with DYT1 dystonia show aberrant risk-aversion in a simple decision-making task, in accordance with predictions of a reinforcement learning model of corticostriatal trial-and-error learning.
