A new hardware-software coil positioning system for interleaved TMS/fMRI: A motor cortex stimulation study
نویسندگان
چکیده
Interleaved TMS/fMRI is a promising technique to study connectivity between brain areas. Functional connectivity can be assessed by targeting a cortical area-of-interest using TMS (Transcranial Magnetic Stimulation) and directly monitoring the effects on local and remote BOLD activity by means of fMRI. An important practical challenge is the accurate positioning of the coil inside the MRI scanner. Here, we describe a novel positioning method and report pilot results on its usage studying the motor system.

Unilateral left prefrontal transcranial magnetic stimulation (TMS) produces intensity-dependent bilateral effects as measured by interleaved BOLD fMRI.
Transcranial magnetic stimulation (TMS) administered over the prefrontal cortex has been shown to subtly influence neuropsychological tasks, and has antidepressant effects when applied daily for several weeks. Prefrontal TMS does not, however, produce an immediate easily observable effect, making it hard to determine if one has stimulated the cortex. Most prefrontal TMS studies have stimulated ...

متن کاملA novel coil array for combined TMS/fMRI experiments at 3 T.
PURPOSE To overcome current limitations in combined transcranial magnetic stimulation (TMS) and functional magnetic resonance imaging (fMRI) studies by employing a dedicated coil array design for 3 Tesla. METHODS The state-of-the-art setup for concurrent TMS/fMRI is to use a large birdcage head coil, with the TMS between the subject's head and the MR coil. This setup has drawbacks in sensitiv...
