Effect of Amygdala Neurofeedback on Depressive Symptoms and Processing Biases

The purpose of this study is to determine whether upregulating the left amygdala during positive autobiographical memory recall via real time functional magnetic resonance imaging neurofeedback will lead to an improvement in clinician administered ratings of depressive symptoms. The investigators predict that patients with major depressive disorder receiving left amygdala neurofeedback will increase their amygdala response during positive autobiographical memory recall compared to those receiving control feedback from a region not involved in emotional processing and that this ability will be associated with clinically significant improvement.
