Transcranial Magnetic Stimulation (TMS) to treat mind

Receptor activation and even neurogenesis (stem cells) for perhaps more than depression, like Alzheimer's; more targetable than exercise and drugs.

Article for depression in particular: These people believe it affects blood flow for areas they're targeting. A lot of treatments for six weeks to get a good result and I think I remember seeing a documentary mentioning that occasional followups were necessary. Some possible side effects and very minimized seizure risk. Good compliance, though.
