Neurofeedback With Real-Time fMRI for Treatment of PTSD

"Recovery from PTSD symptoms has been modeled experimentally as fear extinction that depends on three interconnected brain regions that involve the amygdala where extinction memories are stored, the subcallosal/subgenual cortex within the medial PFC involved in consolidation of the extinction memory, and the hippocampus which mediates the context specificity of context specificity of extinction.~The two MRI systems are used for human research by many faculty and research groups at Duke and UNC, Chapel Hill. The center has two research dedicated General Electric MR 750 scanners with a field strength of 3 Tesla. These systems use a combination of General Electric production pulse sequences and custom research pulse sequences that have been developed by Brain Imaging and Analysis Center faculty and other MR physicists. The scanners are used for imaging and spectroscopy."
