To try to control their symptoms, they were asked to play a video game while in an MRI scanner, using their own mental strategies to move a computerised rocket - and in doing so they were able to turn down the volume on the external voices they heard as well.
She said all the patients in the study, who each had four turns in the MRI scanner, found that their voices became less external and more internal, making them less stressful. They were also better able to cope with them.
I guess I fully don’t understand changing the voices from external to internal. My voices have always been internal.
