RECOVERS - Realigning Emotion and COgnition Via prEcision Regulation networkS - Phase I Study: Multimodal Computational Modeling of Cognitive Flexibility and Emotion Regulation Networks
Medical University of South Carolina
Summary
In this research study, the investigators are examining how brain activity (electrical and blood flow) changes during tests of emotional processing, attention and memory in the magnetic resonance imaging (MRI) scanner and outside the MRI using functional near-infrared spectroscopy (fNIRS). Investigators are also using non-invasive brain stimulation to probe different parts of the brain and measuring brain activity (electrical and blood flow). Study 1 This study includes healthy participants and researchers hope this will help us develop improved brain-based treatments for emotional difficulties like depression. Study 2 This study includes participants with depression and researchers hope this will help us develop improved brain-based treatments for emotional difficulties like depression.
Description
Investigators hypothesize that targeted neuroplastic changes induced by individually-tailored rTMS will substantially reduce clinical symptoms underlying depression, anxiety and suicidality, and in general, revolutionize non-invasive treatments of mental health disorders. Investigators hypothesize that functional coupling in cognitive flexibility (CF) and emotion regulation (ER) networks is indexed by the phase of the brain's alpha oscillations. Using a novel integrated instrument that enables simultaneous functional magnetic resonance imaging (fMRI), electroencephalography (EEG) and transcran…

Interventions
- DevicefMRI-EEG-TMS
Participants will undergo a magnetic resonance imaging (MRI) scan with combined electroencephalography (EEG), and single-pulse transcranial magnetic stimulation (TMS) while completing cognitive flexibility (CF) and emotion recognition (CR) tasks.
- DevicefNIRS-EEG-TMS
Participants brain activity will be measured using functional near-infrared spectroscopy (fNIRS) with combined electroencephalography (EEG), and single-pulse transcranial magnetic stimulation (TMS) while completing cognitive flexibility (CF) and emotion recognition (CR) tasks.
- DevicefNIRS-EEG-rTMS Interleaved with CBT
Participants brain activity will be measured using functional near-infrared spectroscopy (fNIRS) with combined electroencephalography (EEG), and repetitive transcranial magnetic stimulation (rTMS). rTMS will be delivered via a MagVenture MagPro100 and Cool-B65 coil. The investigators will use a standard resting motor threshold (rMT) determination to determine the TMS dose. Treatment will be delivered at 120% of the motor threshold. The accelerated paradigm will consist 6 session a day for 5-6 days. Each rTMS session will be separated by 30 minutes of Cognitive Behavioral Therapy (CBT). rTMS treatment will be delivered at an individualized left DLPFC target based on each participant's individualized scans from prior neuroimaging sessions.
