    Signed and unsigned reward prediction errors dynamically enhance learning and memory

    Nina Rouhani, Yael Niv
    Throughout learning, both unexpected outcomes and the predictive value of cues modulate learning rate and episodic memory, thereby supporting two seemingly opposing theories of associative learning.

    Reward prediction error does not explain movement selectivity in DMS-projecting dopamine neurons

    Rachel S Lee et al.
    Despite the fundamental relationship between movement and value, they are represented in a separable manner in dopamine neurons.

    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.

    Sensory prediction errors in the human midbrain signal identity violations independent of perceptual distance

    Javier A Suarez et al.
    Activity in the midbrain responds to unexpected changes in outcome identity (i.e. sensory prediction error) but does not scale with perceptual distance between expected and receipt reward.
    1. Neuroscience

    Momentary subjective well-being depends on learning and not reward

    Bastien Blain, Robb B Rutledge
    Analyses show that happiness is not associated with the reward prediction errors resulting from decisions but instead with belief updating and learning the structure of the world.

    Offline replay supports planning in human reinforcement learning

    Ida Momennejad et al.
    fMRI evidence for off-task replay predicts subsequent replanning behavior in humans, suggesting that learning from simulated experience during replay helps update past policies in reinforcement learning.

    Midbrain dopamine neurons compute inferred and cached value prediction errors in a common framework

    Brian F Sadacca et al.
    Midbrain dopamine neurons in rats signal discrepancies between predicted and actual rewards, regardless of whether the rewards are predicted on the basis of experience or inference.

    Opposite initialization to novel cues in dopamine signaling in ventral and posterior striatum in mice

    William Menegas et al.
    Dopamine novelty signals are localized in the posterior tail of the striatum along with general salience signals, while dopamine in the ventral striatum reliably encodes reward prediction error.
    1. Neuroscience

    Midbrain dopamine neurons signal aversion in a reward-context-dependent manner

    Hideyuki Matsumoto et al.
    Dopamine neurons signal value prediction errors (VPEs) integrating information about both reward and aversion, in low reward contexts, whereas VPEs in some dopamine neurons are distorted in high reward contexts.
    1. Neuroscience

    Attenuation of dopamine-modulated prefrontal value signals underlies probabilistic reward learning deficits in old age

    Lieke de Boer et al.
    Attenuated anticipatory activity in ventromedial prefrontal cortex is modulated by dopamine D1 receptor density in nucleus accumbens, and accounts for impaired probabilistic reward learning in older adults.
