This study uses ultrasound neuromodulation to show that the dorsal anterior cingulate cortex and anterior insula have distinct roles in Pavlovian biases: aIns reduces reward credit-taking and punishment ignoring, while dACC increases cue valence as reinforcer signal.

This study uses low-intensity focused ultrasound to modulate human amygdala activity and finds it alters emotional processing and reaction times to ambiguous stimuli.

This study investigates how stake magnitude affects Pavlovian biases and response speed in humans, finding that high stakes slow responses without altering bias magnitude.

This study investigates how pupil dilation reflects effortful action invigoration in overcoming aversive Pavlovian biases during a task involving subliminal emotional cues.

The paper shows that instrumental action plans shape selective attention to reward/punishment information, which biases Pavlovian responses and improves performance.

This study investigates how cortical dopamine affects motivational biases in automated behavior using a pharmacological intervention in healthy individuals.

The paper examines how striatal BOLD and midfrontal theta power relate to motivation for action during a Go/NoGo task, finding distinct roles for early and late theta components in reflecting motivational biases and behavioral responses.

The paper shows that cortical regions encode biased prediction errors before subcortical regions during action-outcome learning.

The paper examines pupil diameter changes during task switches between cognitive labor and leisure, finding similar patterns in both directions and suggesting a role for norepinephrine in task reorientation.
