While rTMS does not produce mood changes until after weeks of treatment, unconscious changes in emotional processing have been found even after one session of stimulation. It is unknown whether one session of rTMS produces changes in neural activity to emotional stimuli in depressed adolescents. If acute rTMS can reliably produce changes in neural activity associated with emotional processing it could be a biomarker to aid future dose-finding studies. A one-session protocol allows experimenters to truthfully reduce expectancy of mood change and reduce placebo effects. This study will examine the feasibility of recruitment and using a one-session protocol to find a biomarker for acute rTMS effects. A single-blinded sham-controlled design will be used. Depressed adolescents will undergo: 1) sham stimulation (n=15) or 2) active stimulation with intermittent theta burst stimulation (iTBS) (n=15) for one session prior to assessment of brain activity in response to emotional stimuli in a fMRI and other emotional processing tasks. This one day randomized controlled phase can then lead into an open-label treatment phase active rTMS for 4 weeks. The primary outcome will be recruitment rates with a secondary outcome of estimating the magnitude of difference detectable in cortico-limbic activity between groups. This study assesses the feasibility of a novel paradigm to help improve clinical trials for neuromodulation in depressed adolescents.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD', 'ADULT'], 'maximumAge': '21 Years', 'minimumAge': '14 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n1.
