There is quite a lot of published information about how the left hemisphere is under- active in depression. Traditional TMS is given at high frequencies to the left hemisphere, with about a 50% improvement ( of 50% or more on standard tests). This is thought to be due to increasing the activity of the left hemisphere
Recently, there has been increasing interest in giving low frequency TMS to the right hemisphere. Low frequencies have the opposite effect; they damp down the activity of the hemisphere. There are recent reports of low- intensity treatment of the right hemisphere being even more effective than high- intensity left hemisphere stimulation in improving depressive symptoms.
It would be important to know how differing emotional organization of the brain in left-handed people would influence which hemisphere, and at what intensity, electrical stimulation would be most effective. I haven't found anything about that yet.
