The paper shows that zero prediction errors in reinforcement learning lead to unique psychological and neural responses, challenging the assumption that only unexpected outcomes drive belief updates.

The paper investigates subcortical nuclei activity during reward anticipation and memory encoding, finding increased activity during reward anticipation but no predictive effect on memory.

This study shows that pupil size during rest correlates with activity in subcortical arousal system nuclei, indicating a noninvasive index of their activation.

This study replicates a previous finding that transcutaneous auricular vagus nerve stimulation (taVNS) increases reward-seeking behavior, but fails to confirm the effect, suggesting it may not reliably boost motivation to work for rewards.

This study replicates findings from Sharon et al. (2021) on taVNS effects, confirming pupil dilation but not EEG alpha power changes.
