sTMS is a safe and promising treatment for major depression. Sham-controlled and open-label data suggest that 20-30 treatments with sTMS alone may be beneficial for patients with depression and uniquely effective for treatment-resistant depression. sTMS offers a potential new form of TMS for treatment of depression.

The present study demonstrated significant increase in local and remote cortical functional connectivity in the opioid dependent patients during short-term withdrawal period, thus suggesting that increased inter-area communication among cortical areas may be one of the neurobiological underpinnings of the biased motivational and cognitive processes such as attention, emotions, and memories during withdrawal (see Drummond, 2001; Franken, 2003) supporting the removal of the aversive state behavior.
