This study investigates how the endogenous opioid system modulates brain responses to threat and safety signals in humans using fMRI and PET.

This study shows that pleasurable music activates μ-opioid receptors in the brain, as evidenced by PET and fMRI, and links individual differences in baseline receptor levels to pleasure responses.

This study uses fMRI to show that vicarious feeding activates motor and affective brain regions and that these responses decrease with higher BMI.

This study finds reduced D2R availability in psychopathic offenders compared to controls, suggesting a potential neuromolecular pathway for psychopathy.

The paper investigates the neural basis of laughter and crying using fMRI and MVPA, finding distinct brain networks for each emotion with overlapping suppression.

This study investigates how mu-opioid receptor availability relates to brain responses to laughter and crying sounds in humans using PET-fMRI.

The paper examines neural responses to biological motion in neurotypical individuals, finding distinct associations with autistic and schizotypal traits through fMRI and synchronization analysis.

The paper compares neural responses to emotional stimuli in psychopathy and high-functioning autism, finding distinct patterns of somatomotor alterations.

The paper uses brain activity patterns from visual sexual stimuli to accurately classify sex in subjects.

This study maps neural responses to social features in the human brain using fMRI and identifies spatial patterns of social perception.

This study shows that bariatric surgery restores disrupted opioid-dopamine interaction in the ventral striatum of obese individuals.

This study identifies distinct neural systems for acute and sustained fear using fMRI and ISC analysis in humans watching horror movies.
