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 uses fMRI to show that sensory cortices reflect physical similarity more than idiosyncratic perceptual similarity, while the left angular gyrus reflects idiosyncratic similarity across modalities.

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

This study identifies distinct neural patterns in PTSD patients for traumatic versus sad memories, showing divergent hippocampal representations and symptom severity effects in the posterior cingulate cortex.

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

This study shows that targeted memory reactivation during sleep improves memory for specific words associated with local brain activity, modulating slow wave activity in the cued hemisphere.
