2014
AF Leuchter, et al.
Subjects who received sTMS per-protocol (N = 59) had significantly greater mean decrease in HamD17 scores after six weeks than those receiving sham treatment (N = 61) (-9.00 versus -6.56, p=0.033).
Tuning out the Blues - Thalamo-Cortical Rhythms as a Successful Target for Treating Depression
2015
Frolich
In the case of psychiatric disorders, specific changes in the rhythmic activity structure of (thalamo-) cortical networks have been identified that correlate with behavioral and cognitive symptoms [3]. These pathological network dynamics represent a promising target for brain stimulation.

2019
Griffiths, et al.
The results show that rTMS significantly improved all measures of depression and anxietyResponse and remission rates for depression were 34.6% and 20.6% for the HAM-D; 10% and 28.6% for the PHQ-9; 31% and 31.8% for the CGI; and for anxiety they were and 24.6% and 28.8% (GAD-7)
Low-Field Synchronized Transcranial Magnetic Stimulation (sTMS) for Treatment of Depression: Results from an Open-label Extension Study
2017
Mahendra T. Bhati, M.D., Michael E. Thase, M.D., Jonathan L. Bissett, B.S., Joseph M. Massaro, Ph.D., Andrew F. Leuchter, M.D.
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.

Opioid withdrawal results in an increased local and remote functional connectivity at EEG alpha and beta frequency bands
2007

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.
