Researchers modified current transcranial magnetic stimulation technology to improve its effectiveness for treating depression. The new system, Stanford Accelerated Intelligent Neuromodulation Therapy (SAINT), targeted the subregion between the dorsolateral prefrontal cortex and subgenual cingulate in patients suffering from depression. The treatment delivered rapid relief from depression symptoms for 90% of the test subjects. For 60% of recipients, the effects lasted for more than one-month post-treatment.
