The Impact of Memory and Stress on Choice Consistency

This study investigates how memory and stress affect choice consistency using computational modeling, neuroimaging, and behavioral assessments, finding that stress impairs memory retrieval and choice consistency.

Age-dependent changes in the dynamic functional organization of the brain at rest - a cross - cultural replication approach

This study investigates age-related changes in dynamic functional connectivity across two cultures, finding consistent patterns of reduced segregated connectivity and increased network transitions in older adults.

Secondary rewards acquire enhanced incentive motivation via increasing anticipatory activity of the lateral orbitofrontal cortex

This study shows that secondary rewards like money gain increased incentive motivation through heightened anticipatory activity in the lateral orbitofrontal cortex, unlike primary rewards which decrease in value with satiation.

Intrinsic connectivity of the prefrontal cortex and striato-limbic system respectively differentiate Major Depressive from Generalized Anxiety Disorder

This study identifies distinct intrinsic connectivity patterns in MDD and GAD using resting-state fMRI, highlighting disorder-specific neural markers.

Oxytocin differentially modulates amygdala responses during top-down and bottom-up aversive anticipation

This study investigates how oxytocin modulates amygdala responses during top-down and bottom-up aversive anticipation in individuals with varying trait anxiety levels.

Altered Sensorimotor-to-Transmodal Hierarchical Organization in Schizophrenia

This study shows that schizophrenia is associated with a compressed cortical hierarchy organization, reducing the separation between sensory and cognitive systems.

Cue-reactivity in the ventral striatum characterizes heavy cannabis use, whereas reactivity in the dorsal striatum mediates dependent use

This study examines cue-reactivity in striatal regions of heavy cannabis users to differentiate between addiction-related and exposure-related adaptations.

Oxytocin modulates the intrinsic dynamics between attention-related large scale networks

This study investigates how oxytocin modulates intrinsic functional dynamics between attention-related large-scale brain networks in humans.

Shifted balance of dorsal versus ventral striatal communication with frontal reward and regulatory regions in cannabis dependence

This study uses resting state fMRI to examine a shift in striatal connectivity patterns in cannabis-dependent individuals compared to controls, finding increased ventral striatum connectivity with reward regions and reduced connectivity with regulatory regions.
