The paper records single neuron activity in the substantia nigra during social learning tasks and finds dopaminergic neurons encode norm prediction error valence more strongly during human vs computer interactions.

The paper shows that nicotine-related beliefs in smokers induce dose-like thalamic responses and functional coupling with prefrontal cortex, similar to pharmacological effects.

The paper shows humans use forward thinking to guide social choices, with neural activity reflecting control beliefs in specific brain regions.
