Abstract

Neuroimaging and cognitive neuroscience studies have identified neural circuits linked to anxiety, mood, and trauma-related symptoms and focused on their interaction with the medial prefrontal default mode circuitry. Despite these advances, developing new neuromodulatory treatments based on neurocircuitry remains challenging. It remains unclear which nodes within and controlling these circuits are affected and how their impairment is connected to psychiatric symptoms. Concurrent single-pulse (sp) TMS/fMRI offers a promising approach to probing and mapping the integrity of these circuits. In this study, we present concurrent spTMS/fMRI data along with structural MRI scans from 152 participants, across 4 clinical groupings: Non-trauma Exposed Healthy Controls (NTHC; n = 46), Trauma Exposed Healthy Controls (TEHC; n = 29), Non-trauma Induced Symptomatic (NTS; n = 43), Trauma Induced Symptomatic (NIS; n = 34).The spTMS was administered to 11 different cortical sites, providing a dataset that allows researchers to investigate how brain circuits are modulated by spTMS.

Project Timeline and Stimulation Paradigm at different resolutions. (a) Study consists of 2 sessions, the first being MRI acquisition without TMS, and the second including TMS. There were 11 TMS-fMRI runs, each corresponding to an identified cortical region from day 1. (b) The concurrent TMS-fMRI period lasts for ~167 effective TRs where an effective TR is 2400 ms. (c) 1 Effective TR = 2400 ms where 1 Actual TR = 2100 ms. A 300 ms gap is left in which stimulation may or may not occur. Stimulation occurs on a jittered 6-7 TR basis.
