Individualized (fMRI-guided) TMS Treatment for Depression
Recruiting
The purpose of this study is to investigate the responses of the brain region known as the subgenual anterior cingulate cortex (sgACC) during transcranial magnetic stimulation (TMS) in individuals with depression. Specifically, investigators aim to determine whether the sgACC is engaged when TMS is delivered to specific targets and if the engagement of sgACC changes throughout a full TMS treatment intervention. To achieve this goal, the investigators will employ a combination of TMS and Magnetic... Read More

Gamma Oscillations as a Prognostic Marker for Ketamine Therapy in Treatment Resistant Depression
Recruiting
The core objective of this study is to enhance the translational potential of this electroencephalogram (EEG) biomarker by using ketamine(KET)-induced gamma potentiation as a prognostic marker of 4-week treatment outcome. Previous research focused exclusively on KET-induced gamma band potentiation (GBP) in the context of a single infusion. Our study design captures the clinical variation associated with real-world treatment resistant depression (TRD) patients and allows us to analyze the relativ... Read More
