CEREBRAL GLUCOSE UTILISATION DURING MUSICAL EMOTIONS: A MULTIMODAL FUNCTIONAL PET/MRI STUDY.

This study uses PET/MRI to examine glucose metabolism and hemodynamic responses during pleasurable music listening, revealing complementary neural activity patterns in brain regions associated with reward and emotion.

Endogenous opioid system modulates proximal and distal threat signals in the human brain

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

Exposure to bullying engages social distress circuits in the adolescent and adult brain

This study uses fMRI to examine neural responses to simulated bullying in adolescents and adults, finding activation of socio-emotional and threat response systems linked to victimization experiences.

Physical exercise and brain network dynamics: reduction of frontoparietal-striatal connectivity following 1 hour of aerobic cycling

This study examines changes in brain network dynamics after 60 minutes of aerobic cycling, finding reduced striato-frontoparietal connectivity.

Pleasurable music activates cerebral μ-opioid receptors: A combined PET-fMRI study

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.

Endogenous opioid receptor system mediates costly altruism in the human brain

The paper investigates how the endogenous opioid receptor system influences altruistic costly helping by linking MOR availability to brain activity during vicarious pain and helping behavior.

Reward responses to vicarious feeding depend on BMI

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

Dopamine D2R and opioid MOR availability in autism spectrum disorder

This study investigates dopamine D2R and opioid MOR receptor availabilities in ASD using PET imaging and finds reduced D2R availability in striatum and nucleus accumbens, and MOR changes in hippocampi and precuneus.

Aberrant type 2 dopamine receptor availability in criminal psychopathy

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

Decoding brain basis of laughter and crying in natural scenes.

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

Endogenous opioid release following orgasm in man: A combined PET-fMRI study

This study uses PET and fMRI to show endogenous opioid release in the hippocampus and increased hemodynamic activity in brain regions associated with sexual arousal following orgasm.

Mu-opioid receptor system modulates responses to vocal bonding and distress signals in humans

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

Neural responses to biological motion distinguish autistic and schizotypal traits in the general population

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

Aberrant motor contagion of emotions in psychopathy and high-functioning autism

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

Accurate sex classification from neural responses to sexual stimuli

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

Functional organization of social perception in the human brain

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

Cerebral μ-opioid and CB1-receptor systems have distinct roles in human feeding behavior

This study investigates the role of cerebral μ-opioid and CB1-receptor systems in human feeding behavior using PET scans and the Dutch Eating Behavior Questionnaire.

Seasonal variation in brain mu-opioid receptor availability

This study finds seasonal variation in brain mu-opioid receptor availability in humans, showing an inverted U-shaped relationship with daylength.

Decoding music-evoked emotions in the auditory and motor cortex

The paper investigates the neural basis of music-evoked emotions using fMRI, finding distinct brain activity patterns for different emotions in auditory and motor regions.

Interindividual variability and lateralization of μ-opioid receptors in the human brain

This study quantifies interindividual variability and hemispheric lateralization of μ-opioid receptors in the human brain using PET and Bayesian modeling.

Magia: Robust automated image processing and kinetic modeling toolbox for PET neuroinformatics

Magia automates PET brain data processing, producing outcome measures consistent with manual methods despite anatomical differences in reference regions.

Dissociable neural systems for unconditioned acute and sustained fear

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