        abstract = {The brain's sensitivity to unexpected outcomes plays a fundamental role in an
organism's ability to adapt and learn new behaviors. Emerging research suggests that
midbrain dopaminergic neurons encode these unexpected outcomes. We used
microelectrode recordings during deep brain stimulation surgery to study neuronal activity in
the human substantia nigra (SN) while patients with Parkinson's disease engaged in a
probabilistic learning task motivated by virtual financial rewards. Based on a model of the ...}
