PiR HEG neurofeedback training has many benefits. Initially developed by Jeffrey Carmen PhD for the treatment of migraines, he discovered that not only did it have a great effect on reducing the severity and frequency of migraines but also that training the prefrontal cortex with neurofeedback increased the executive functions of the trainees. He continued researching and discovered that people who had reported having chronic or temporary undesirable mood states tended to have reduced prefrontal cortex activation when a thermal image was taken of their foreheads. Down below are before and after infrared pictures of people who had various conditions.
Before: Dark spot indicates abnormal prefrontal metabolism; client says she feels depressed
After one session: Dark spot is gone; prefrontal metabolism has increased and this client reports that she is feeling much better
Before: This client has cognitive deficits and this is verified by the reduced temperature indicating low prefrontal metabolism
After: Prefrontal metabolism has increased; client indicated that his thoughts are "flowing more smoothly"
