    Competition between parallel sensorimotor learning systems

    Scott T Albert, Jihoon Jang ... Reza Shadmehr
    When a common error drives parallel implicit and explicit learning systems, increases in the explicit response will suppress implicit adaptation.

    Control of entropy in neural models of environmental state

    Timothy H Muller, Rogier B Mars ... Jill X O'Reilly
    Evidence for neuromodulatory control of flexibility in human neural models.

    Unimodal statistical learning produces multimodal object-like representations

    Gábor Lengyel, Goda Žalalytė ... Daniel M Wolpert
    Mere exposure to scenes with statistical contingencies in the visual or haptic modality alone allows participants to decompose scenes into object-like multimodal representations.

    Atypical cognitive training-induced learning and brain plasticity and their relation to insistence on sameness in children with autism

    Jin Liu, Hyesang Chang ... Vinod Menon
    Learning in children with autism spectrum disorder (ASD) was achieved by fundamentally different cognitive and neural mechanisms from typically developing children, and insistence on sameness, a core symptom of ASD, contributed to such atypical mechanisms of learning in affected children.

    Rules and mechanisms for efficient two-stage learning in neural circuits

    Tiberiu Teşileanu, Bence Ölveczky, Vijay Balasubramanian
    Teaching signals from "tutor" brain areas should be adapted to the plasticity mechanisms in "student" areas to achieve efficient learning in two-stage systems such as the vocal control circuit of the songbird.

    Computational modeling of threat learning reveals links with anxiety and neuroanatomy in humans

    Rany Abend, Diana Burk ... Bruno B Averbeck
    Applying computational modeling to quantify threat learning processes uncovers how variations in these conserved learning processes relate to anxiety severity and the neuroanatomical substrates moderating these associations.

    Inhibitory muscarinic acetylcholine receptors enhance aversive olfactory learning in adult Drosophila

    Noa Bielopolski, Hoger Amin ... Moshe Parnas
    Muscarinic acetylcholine receptor type A in adult Drosophila inhibits Kenyon cells, and is required for aversive olfactory learning and learning-associated synaptic depression between Kenyon cells and their output neurons.

    Catecholaminergic modulation of meta-learning

    Jennifer L Cook, Jennifer C Swart ... Roshan Cools
    A human psychopharmacology study reveals that a drug that affects the dopamine and noradrenaline systems enhances people's ability to adapt their learning rate to suit the volatility of the environment.

    Computational mechanisms of curiosity and goal-directed exploration

    Philipp Schwartenbeck, Johannes Passecker ... Karl J Friston
    Distinct computational levels of uncertainty compel agents to gain information about hidden states in the world (‘active inference’) or optimise their ‘world model’ as such (‘active learning’).
    1. Neuroscience

    Homeostatic reinforcement learning for integrating reward collection and physiological stability

    Mehdi Keramati, Boris Gutkin
    A mathematical model built around the assumption that the desire to maintain internal homeostasis drives the behavior of animals, by affecting their learning processes, can explain many real-world behaviors, including some that might otherwise appear irrational.
