About the study
Transcranial magnetic stimulation (TMS) is increasingly being applied to effectively treat mental illness, however efforts to quantify the effects of TMS on the network architecture of the brain have largely been limited in scope and tied to specific neurologic and psychiatric disorders. The objective of the current work is to build and validate a whole-brain, domain-general model of brain connectivity changes following TMS, based on physical models of the current distribution at the cortex. PUBLIC HEALTH RELEVANCE: This work is relevant to public health because it will provide direct evidence that brain connectivity changes following neuromodulatory TMS vary as a function of the current density at the cortex, which can be used to predict psychiatric symptom change following neuromodulatory TMS.
