    Reward-based training of recurrent neural networks for cognitive and value-based tasks

    H Francis Song et al.
    A two-part neural network models reward-based training and provides a unified framework in which to study diverse computations that can be compared to electrophysiological recordings from behaving animals.

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

    Tiberiu Teşileanu et al.
    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.

    Complementary contributions of basolateral amygdala and orbitofrontal cortex to value learning under uncertainty

    Alexandra Stolyarova, Alicia Izquierdo
    Rat orbitofrontal cortex is required to accurately represent outcome distributions, whereas basolateral amygdala is necessary for the facilitation of learning in response to surprising events.

    The modulation of savouring by prediction error and its effects on choice

    Kiyohito Iigaya et al.
    The anticipation of rewards turns out to have its own hedonic value, on top of that of the reward itself; a wide range of behavioral and neurophysiological data suggest that this anticipation is boosted by prediction errors.

    Neural activity in cortico-basal ganglia circuits of juvenile songbirds encodes performance during goal-directed learning

    Jennifer M Achiro et al.
    Activity in cortico-basal ganglia circuits of juvenile songbirds reflects evaluative signals necessary for comparing self-generated behavior to a goal representation during skill learning.

    Neural and computational processes underlying dynamic changes in self-esteem

    Geert-Jan Will et al.
    Self-esteem, the value that people ascribe to the self, is represented in the ventromedial prefrontal cortex and dynamically updated when people learn how others value them.

    Two-photon imaging in mice shows striosomes and matrix have overlapping but differential reinforcement-related responses

    Bernard Bloem et al.
    Simultaneous 2-photon imaging of striosomes and matrix in mice shows that striosomes preferentially encode reward-predicting cues whereas both striatal compartments demonstrate reward-related activity.

    The control of tonic pain by active relief learning

    Suyi Zhang et al.
    The brain has a central cortico-striatal learning circuit that suppresses ongoing pain after injury when actively learning about things that could remove the cause of the pain.

    A causal role for right frontopolar cortex in directed, but not random, exploration

    Wojciech K Zajkowski et al.
    Disruption of right frontopolar cortex with transcranial magnetic stimulation causes selective deficits in exploratory behavior suggesting that different strategies of exploration are implemented by different neural circuits.

    Motor thalamus supports striatum-driven reinforcement

    Arnaud L Lalive et al.
    While the basal ganglia have long been thought to mediate learning through dopamine-dependent striatal plasticity, their regulation of motor thalamus plays an unexpected and critical role in reinforcement.
