Meditation Accelerated Brain Stimulation for Depression
Purpose
Repetitive Transcranial magnetic stimulation (rTMS) is an FDA-approved treatment for depression that involves brief magnetic stimulation pulses on the dorsolateral prefrontal cortex (DLPFC) brain region. The ultimate goal of this treatment is to increase excitability and long-term plasticity in DLPFC, a brain region shown to be hypo-active in depression. Unfortunately, rTMS only has low to moderate efficacy; remission rates for patients range from ~15-30% in large randomized controlled trials. The focus of this research is to develop a next-generation rTMS protocol that is guided by the basic principles underlying brain plasticity, in order to improve the efficacy of rTMS for the treatment of depression. Specifically, in this study the investigators will test rTMS paired with a depression-relevant cognitive state of internal attention.

Detailed Description
Repetitive Transcranial magnetic stimulation (rTMS) is an FDA-approved treatment for depression that involves brief magnetic stimulation pulses on the dorsolateral prefrontal cortex (DLPFC) brain region. The ultimate goal of this treatment is to increase excitability and long-term plasticity in DLPFC, a brain region shown to be hypo-active in depression. Unfortunately, rTMS only has low to moderate efficacy; remission rates for patients range from ~15-30% in large randomized controlled trials. The focus of this research is to develop a next-generation rTMS protocol that is guided by the basic principles underlying brain plasticity, in order to improve the efficacy of rTMS for the treatment of depression. Specifically, in this study the investigators will test rTMS paired with a depression-relevant cognitive state of internal attention. Meditative internal focus has been shown to benefit depression. Our own research shows that the neural correlates of attention-to-breath are associated with greater mindfulness. Hence, in this study we will pair breath training with rTMS neuro-stimulation.
