New neuroimaging technique studies brain stimulation for depression

Despite increased use of repetitive transcranial magnetic stimulation in psychiatry, the rates at which patients respond to the therapy and experience remission of often-disabling symptoms have been modest at best. Now, a team of psychiatrists and biomedical engineers applied an emerging functional neuroimaging technology, known as diffuse optical tomography (DOT), to better understand how rTMS works so they can begin to improve the brain stimulation procedure's effectiveness in treating depression.
