Testing a Neurocognitive Model of Distancing Using Transcranial Magnetic Stimulation.
In Brief
A clinical study evaluating Transcranial magnetic stimulation task and Sham transcranial magnetic stimulation task for Emotion Regulation and Real Versus Sham Transcranial Magnetic Stimulation (TMS). Completed, enrolled 40 participants across 1 site.
Detailed Summary
Distancing oneself from a current distressing situation is a mental skill that can help people to manage their emotions. However, little is known about how distancing works in the brain. Recently developed tools in neuroscience that can modify brain activity might be able to make distancing more or less effective. In doing so, the results could lead to a better understanding of the cognitive processes and neural circuits that support distancing as a form of emotion regulation. If successful, this research may lead to the development of new treatments to help those who suffer from stress-related disorders, such as anxiety and depression.

Timeline
Interventions
Experimenters will employ a continuous theta-burst stimulation (cTBS) sequence using a figure-8 coil positioned tangentially to the scalp over the target coordinates. Experimenters have defined the target coordinates for stimulation (Montreal Neuroscience Institute coordinates -53, -53, 23) based on peak objective distancing activation in the left temporal parietal junction (TPJ) in previous fMRI studies using the same task.
A sham version of the TMS intervention where subjects will receive a small electrical stimulation on the scalp via two small electrodes in conjunction with a TMS coil activation. The TMS coil will be reoriented to stimulate into the air away from the scalp, simulating traditional TMS, without inducing any current to the subject.
