Neuroimaging of depression with diffuse optical tomography during repetitive transcranial magnetic stimulation

Abstract Repetitive transcranial magnetic stimulation (rTMS) is an effective and safe treatment for depression; however, its potential has likely been hindered due to non-optimized targeting, unclear ideal stimulation parameters, and lack of information regarding how the brain is physiologically res...
