How does rTMS work?

Page 10: R tms for depression by dr ajay nihalani

• Magnetic stimulation leads to either an increase or decrease in brain activity in targeted brain area.

14:25 GMT, 9 May 2012 • Depression affects one in four of us at some point of

our lives, but controversy still reigns over how to best treat the debilitating condition.

• Now scientists have found that a type of 'magnetic therapy' - which involves no brain-altering drugs or invasive procedures - could be a potent new treatment.
