    Synaptic memory requires CaMKII

    Wucheng Tao, Joel Lee ... Roger A Nicoll
    Physiology studies demonstrate that CaMKII is a molecular storage device.

    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.

    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.

    Group III metabotropic glutamate receptors gate long-term potentiation and synaptic tagging/capture in rat hippocampal area CA2

    Ananya Dasgupta, Yu Jia Lim ... Sreedharan Sajikumar
    Group III metabotropic glutamate receptor inhibition facilitates synaptic plasticity in the plasticity-resistant synapses of hippocampal area CA2, a brain region critical for social memory.

    Structural plasticity of dendritic secretory compartments during LTP-induced synaptogenesis

    Yelena D Kulik, Deborah J Watson ... Kristen M Harris
    The secretory and recycling components of neuronal dendrites, smooth endoplasmic reticulum and endosomes, were discovered to support synaptogenesis underlying a cellular mechanism of learning and memory in the developing brain.

    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.
    1. Neuroscience

    Glucocorticoid receptor-mediated amygdalar metaplasticity underlies adaptive modulation of fear memory by stress

    Ran Inoue, Kareem Abdou ... Hisashi Mori
    Behavioral analyses and an optogenetic approach reveal an existence of GR-mediated metaplasticity in the LA and its link with adaptive fear response to auditory cues in a stressful condition.

    cAMP−EPAC−PKCε−RIM1α signaling regulates presynaptic long-term potentiation and motor learning

    Xin-Tai Wang, Lin Zhou ... Ying Shen
    Mouse models with specific presynaptic knockout demonstrate that Rim1α is subjected to threonine phosphorylation by a novel EPAC-PKCε module, which is essential to presynaptic transmitter release, required for the induction of presynaptic LTP, and critical for motor learning.
