Alpha oscillation neurofeedback modulates amygdala complex connectivity and arousal in posttraumatic stress disorder

•Alpha desynchronizing neurofeedback was associated with a shift in amygdala complex connectivity.•Connectivity shifted from areas implicated in defensive fear processing/memory retrieval, to prefrontal emotion regulation areas.•Shift in amygdala complex connectivity was associated with reduced arou...
