This study revealed associations between sleep and depression but no correlation between sleep and spinal cord stimulation (Source: Florida Atlantic University) Article Addresses How fMRI Technology May Help Inform Brain Stimulation Jan. 27, 2023 - Ultrafast fMRI can now capture brain activity at sub-second levels which allows for real-time brain monitoring under simulation conditions. Associate Professor Kai-Hsiang Chuang’s laboratory at the Queensland Brain Institute (QBI) found that brain activity is dependent on one’s state, and that blood signal detected by fMRI may reflect network organization and cell type distribution.
