Measure
Active Versus Sham TMS
Active or sham TMS will initially be targeted to asymmetric cortical activation in one hemisphere, as defined by PET-CT imaging according to a randomized schedule. This area will then be targeted either for active treatment with rTMS at 1-Hz frequency, delivering 1800 pulses at 110% MT on each of 5 consecutive treatment days or sham treatment of the same duration.
