    1. Neuroscience

    Unsupervised changes in core object recognition behavior are predicted by neural plasticity in inferior temporal cortex

    Xiaoxuan Jia, Ha Hong, James J DiCarlo
    Temporal continuity-induced plasticity in individual neurons of inferior temporal cortex builds neural representations that underlie robust core object recognition behavior.

    The generation of cortical novelty responses through inhibitory plasticity

    Auguste Schulz, Christoph Miehl ... Julijana Gjorgjieva
    Inhibitory synaptic plasticity provides a flexible and biologically plausible circuit mechanism to detect the novelty of bottom-up stimuli and to generate stimulus-specific adaptation.

    Evolving interpretable plasticity for spiking networks

    Jakob Jordan, Maximilian Schmidt ... Mihai A Petrovici
    Artificial evolution discovers biophysically plausible plasticity rules for spiking networks that perform competitively with and even outperform labor-intensive human-designed models in various learning scenarios, while providing new views on experimental data.

    GABA, not BOLD, reveals dissociable learning-dependent plasticity mechanisms in the human brain

    Polytimi Frangou, Marta Correia, Zoe Kourtzi
    Combining GABA with fMRI measurements in the human brain uncovers distinct suppression mechanisms that optimize perceptual decisions through learning and experience-dependent plasticity in the visual cortex.

    Bidirectional synaptic plasticity rapidly modifies hippocampal representations

    Aaron D Milstein, Yiding Li ... Sandro Romani
    Dendritic calcium spikes translocate hippocampal place fields by inducing a non-Hebbian form of bidirectional synaptic plasticity that operates over a seconds-long timescale called behavioral timescale synaptic plasticity.

    Interactions between circuit architecture and plasticity in a closed-loop cerebellar system

    Hannah L Payne, Jennifer L Raymond, Mark S Goldman
    A comprehensive modeling approach reconciles experimental observations with classic plasticity mechanisms in the cerebellar cortex, demonstrating how learning-related changes in neural activity can appear to contradict the sign of the underlying plasticity when feedback is present.
    1. Neuroscience

    Presynaptic stochasticity improves energy efficiency and helps alleviate the stability-plasticity dilemma

    Simon Schug, Frederik Benzing, Angelika Steger
    Presynaptic plasticity in simulated neural networks with a simple biologically plausible learning rule improves metabolic efficiency and lifelong learning capabilities.
    1. Neuroscience

    The locus coeruleus broadcasts prediction errors across the cortex to promote sensorimotor plasticity

    Rebecca Jordan, Georg B Keller
    A brain-wide neuromodulatory system enables rapid cortical plasticity to occur by signaling sensorimotor prediction errors across wide regions of the cerebral cortex.
