What this trial is about
This is a study that will recruit patients from the neurosurgery clinic and the regular TMS clinic. It's a smaller study designed to collect brain imaging pre-treatment and then use image guided TMS to treat patient with a one week "accelerated" rTMS protocol using the research TMS machine that is housed in Dr. Sean Nestor's lab. The idea is to examine whether severe treatment resistant depression has a different brain signature than less severe/TRD and whether the investigators can get a therapeutic response from patients that would otherwise undergo neurosurgery or will ultimately undergo neurosurgery.
