This study uses fMRI to examine empathy processing in bvFTD patients and controls, finding reduced BOLD signal in key regions and altered connectivity patterns.

This paper introduces a QDA framework for resting-state fMRI analysis to study age-related changes in functional connectivity, finding age-related declines in specific brain regions and enhanced sensitivity through separate assessment of positive and negative connectivity.

The paper shows that viewing pictures rapidly increases gray matter volume and cortical thickness in the visual cortex within 263 seconds.

This study investigates how sleep restriction affects emotional regulation using fMRI, finding increased prefrontal cortex activity in young participants but no brain activation changes in either age group.

This study examines how partial sleep deprivation affects intrinsic brain connectivity in young and older adults using fMRI and finds increased global signal variability but no significant changes in resting state networks.
