rTMS Pilot for Anxiety

Aims 1 and 2 of this project will be tested using a within-subjects design where anxiety patients will receive a 5-day course of accelerated 1 Hz rTMS (8x session x 600 pulses/session) to the right IPS. In Aim 1, we will test the effects of this stimulation on arousal during the NPU threat task (NPU section). In Aim 2 below, we will test the effects of this stimulation on arousal-related attention control deficits using the VSTM task (VSTM section). Subjects will undergo 7 study visits spaced over a roughly 3-week period depending upon availability. First, subjects will have a pre-stimulation test visit. On this visit they will undergo the following procedures: 1) motor threshold testing, 2) noise habituation, 3) shock workup 4) NPU task, 5) VSTM task. Then they will have 5 rTMS visits. On these visits, subjects will receive 8 trains of 1 Hz rTMS (600 pulses per train, each separated by \~50 min). Finally, they will have a post-stimulation test visit, which will included the noise habituation, shock workup, NPU task, and VSTM task.
