Researchers have shown what happens to the brain when a person receives a depression treatment known as repetitive transcranial magnetic stimulation (rTMS). rTMS is a depression treatment typically used when other approaches — such as medications — haven’t been effective for a patient. By stimulating the dorsolateral pre-frontal cortex, rTMS activates several other regions of the brain involved in multiple functions, from managing emotional responses to memory and motor control.
