A therapeutic brain stimulation system comprises at least two stimulation signal emitters generating stimulation signals from different positions towards a common target region in a patient's brain. While the signal intensity of each stimulation signal is much too low to cause stimulation, the accumulated stimulation signals cause a stimulation and, thus, a therapeutic effect in the neuronal brain cells of the target region. The stimulation signals accumulating in the target region are adjustable so as not to negatively affect the anatomic structure of neuronal brain cells in the target region.
